[Dovecot] Quotas not recalculating
by Kyle Brantley 07 Sep '11

07 Sep '11

Hello all -- I have an interesting issue, where the quotas are refusing the recalculate for anyone on my server. # doveadm quota get -u kyle(a)averageurl.com Quota name Type Value Limit % storage=540672 STORAGE 0 - 0 storage=540672 MESSAGE 0 - 0 # doveadm quota recalc -u kyle(a)averageurl.com # doveadm quota get -u kyle(a)averageurl.com Quota name Type Value Limit % storage=540672 STORAGE 0 - 0 storage=540672 MESSAGE 0 - 0 # du -sh /var/mail/vhosts/averageurl.com/kyle 512M /var/mail/vhosts/averageurl.com/kyle The IMAP client (Thunderbird) state that the user has no quotas in place at all. Now, if I copy the maildirsize file from another user to this user account, the quotas display in the IMAP client. At this point, however, trying to recalc the quota does nothing.

[Dovecot] error in logs, but system appears to work
by Chris Hoogendyk 06 Sep '11

06 Sep '11

I'm bringing up a system with dovecot that has been running for years with uw-imap. In making the switch, I put a tail on the log file, made the switch, and sent a test mail and received it. I was able to receive mail with no apparent difficulties, but the log file was disconcerting. A number of users connected during the few minutes I had it running, and for each of them there was an error, e.g., "chown ~user/mail/.imap/INBOX failed: Operation not permitted" and "mkdir ~user/mail/.imap/INBOX failed: not owner". But those directories and files appeared to have been made. The first of those errors finishes with "group based on /var/mail/user". That makes no sense. I'm hoping someone can give me an idea what might cause this. Here are the log entries in debug mode and the directories for one such user: Sep 2 17:31:33 eclogite dovecot: [ID 583609 local2.info] auth(default): new auth connection: pid=7248 Sep 2 17:31:43 eclogite dovecot: [ID 583609 local2.info] auth(default): client in: AUTH 1 PLAIN service=pop3 secured lip=128.119.45.20 rip=128.119.45.9 lport=995 rport=53865 resp=AGVicmFkbGV5AFJvd2luZzEzKg== Sep 2 17:31:43 eclogite dovecot: [ID 583609 local2.info] auth(default): shadow(ebradley,128.119.45.9): lookup Sep 2 17:31:43 eclogite dovecot: [ID 583609 local2.info] auth(default): client out: OK 1 user=ebradley Sep 2 17:31:43 eclogite dovecot: [ID 583609 local2.info] auth(default): master in: REQUEST 37 7248 1 Sep 2 17:31:43 eclogite dovecot: [ID 583609 local2.info] auth(default): passwd(ebradley,128.119.45.9): lookup Sep 2 17:31:43 eclogite dovecot: [ID 583609 local2.info] auth(default): master out: USER 37 ebradley system_groups_user=ebradley uid=6633 gid=100 home=/u1/home/grad/ebradley Sep 2 17:31:43 eclogite dovecot: [ID 583609 local2.info] POP3(ebradley): Effective uid=6633, gid=100, home=/u1/home/grad/ebradley Sep 2 17:31:43 eclogite dovecot: [ID 583609 local2.info] POP3(ebradley): mbox: data=~/mail:INBOX=/var/mail/ebradley Sep 2 17:31:43 eclogite dovecot: [ID 583609 local2.info] POP3(ebradley): fs: root=/u1/home/grad/ebradley/mail, index=, control=, inbox=/var/mail/ebradley Sep 2 17:31:43 eclogite dovecot: [ID 583609 local2.info] POP3(ebradley): Namespace : Using permissions from /u1/home/grad/ebradley/mail: mode=0700 gid=-1 Sep 2 17:31:43 eclogite dovecot: [ID 583609 local2.error] POP3(ebradley): chown(/u1/home/grad/ebradley/mail/.imap/INBOX, -1, 6(mail)) failed: Operation not permitted (egid=100(geolgrad), group based on /var/mail/ebradley) Sep 2 17:31:43 eclogite dovecot: [ID 583609 local2.error] POP3(ebradley): mkdir(/u1/home/grad/ebradley/mail/.imap/INBOX) failed: Not owner Sep 2 17:31:43 eclogite dovecot: [ID 583609 local2.info] pop3-login: Login: user=<ebradley>, method=PLAIN, rip=128.119.45.9, lip=128.119.45.20, TLS When I looked at their home directory, I found: drwx------ 4 ebradley geolgrad 512 Jul 28 2009 /u1/home/grad/ebradley drwx------ 4 ebradley geolgrad 512 Sep 2 17:31 /u1/home/grad/ebradley/mail drwx------ 3 ebradley geolgrad 512 Sep 2 17:31 /u1/home/grad/ebradley/mail/.imap drwxrwx--- 2 ebradley geolgrad 512 Sep 2 17:31 /u1/home/grad/ebradley/mail/.imap/INBOX -rw-rw---- 1 ebradley mail 9484323 Sep 6 15:16 /var/mail/ebradley My dovecot configuration is at the end.

[Dovecot] Extdata plugin, MySQL
by Steve Fatula 06 Sep '11

06 Sep '11

Does someone have an example of configuring the Pigeonhole Sieve Extdata plugin with MySQL dict? Particularly, the map and what key might be used in this? The doc in the wiki isn;t clear at all to me when one wants to use MySQL store. The file in the doc folder of the mercurial repository is basically what I want to do, in that RFC, it's bascially looking for a discard_spam setting, I presume by user whose Sieve script is running. So, what would the sql mapping file look like? What lookup key is used? I can't really find any map documentation for the syntax, can a special key be used, perhaps, I need to append a value to the user if that is the key? Can this data be accessed via the dictionary proxy to make access more efficient? While I don't want to discard spam based on the setting in the database, I DO want to not move to the spam folder based on a setting stored in an existing MySQL database. So, very similar idea. I want to use an existing database, but, the key is username + a certain constant value for another field. Am hoping this can be mapped as well. Steve

[Dovecot] Mail files?
by Knute Johnson 05 Sep '11

05 Sep '11

I have a Ubuntu server running dovecot 1.2.9 with mail in mbox. There are mail files in /var/mail/user and there are mail files in /home/user/mail that correspond to the IMAP folders. In the config file details below it shows mail_location: mbox:~/mail:INBOX=/var/mail/%u, does that put the INBOX in /var/mail? Is INBOX in /var/mail/user to allow local delivery or something? If I was using POP3 instead would all the mail be in the INBOX? Can I backup these files by just copying and if a file is destroyed, copy them back? # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-33-generic i686 Ubuntu 10.04.3 LTS log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps ssl_cert_file: /etc/ssl/certs/ssl-cert-snakeoil.pem ssl_key_file: /etc/ssl/private/ssl-cert-snakeoil.key login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_max_userip_connections: 16 mail_privileged_group: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u mbox_write_locks: fcntl dotlock imap_capability: IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS auth default: passdb: driver: pam userdb: driver: passwd Thanks, -- Knute Johnson knute2011(a)knutejohnson.com

[Dovecot] v2.1.alpha1 released
by Timo Sirainen 05 Sep '11

05 Sep '11

http://dovecot.org/releases/2.1/alpha/dovecot-2.1.alpha1.tar.gz http://dovecot.org/releases/2.1/alpha/dovecot-2.1.alpha1.tar.gz.sig So it's time for the first alpha version of Dovecot v2.1. There are no huge intrusive changes, so I expect v2.1.0 to be released this year (maybe even in a few months?) The biggest changes are related to full text search handling. I'll probably still make some changes to it and its configuration. Also it wouldn't be difficult to add more backends, does anyone want to add Xapian support for Dovecot? :) Mailbox list indexes are intended to improve performance of IMAP STATUS command lookups, since they could be simply looked up from the index without even opening the mailbox. TODO related to this: 1) optimize virtual mailbox handling so that it doesn't need to actually open all of the mailboxes' index files, it can simply look at the mailbox list index for changes. 2) Implement IMAP NOTIFY extension using this. Statistics tracking can be used to look at what's happening currently in your system and also its history. You can look at what's happening in command/session/user/domain/ip level. "doveadm stats top" gives a list of currently running sessions and sorts them by whichever is using the most disk io/cpu/whatever. "doveadm stats dump" followed by one of the levels shows you a raw dump of everything stored in that level. It would be nice if someone wrote a pretty Ajaxy HTML stats browser where you could zoom in/out of levels. I'd also like to hear if anyone has suggestions on how to improve what stats are gathered or how they could be exported. (I've thought about SNMP, but I'm not entirely sure how to export the data nicely using it.) Finally here's the NEWS file: * Plugins now use UTF-8 mailbox names rather than mUTF-7: acl, autocreate, expire, trash, virtual * auth_username_format default changed to %Lu. If you really want case sensitive usernames, set it back to empty. * Solr full text search backend changed to use mailbox GUIDs instead of mailbox names, requiring reindexing everything. solr_old backend can be used with old indexes to avoid reindexing, but it doesn't support some newer features. + imapc (= IMAP client) storage allows using a remote IMAP server to be used as storage. This allows using Dovecot as a smart (caching) proxy or using dsync to do migration from remote IMAP server. + Mailbox indexing via queuing indexer service (required for Lucene) + Lucene full text search (FTS) backend rewritten with support for different languages + FTS finally supports "OR" search operation + FTS supports indexing attachments via external programs + IMAP FUZZY extension, supported by Lucene and Solr FTS backends + Mailbox list indexes + Statistics tracking via stats service. Exported via doveadm stats. + Autocreate plugin creates/subscribes mailboxes physically only when the mailbox is opened for the first time. Mailbox listing shows the autocreated mailboxes even if they don't physically exist. + Password and user databases now support default_fields and override_fields settings to specify template defaults/overrides. - listescape plugin works perfectly now

[Dovecot] User tries to move folder, then looses it
by Spyros Tsiolis 05 Sep '11

05 Sep '11

Hello, Well, this is kind of difficult to explain. I have this user that keeps making mistakes on his pc and sometimes I don't know if I should believe her or not. Anywhoo, this time round, she managed to loose a whole folder on Thunderbird. She claims she tried to move the folder from a tree directory structure (see : sub-sub-folder) she created for herself to another place underneath "root". Additionaly, she managed to mangle things up since she used on TB characters like "/" "\" and "&" . So thunderbird refuses to access those sub-folders on the folder tree and I cannot rename them (in order to have later access).

[Dovecot] Thunderbird caching problem
by Chris Cappuccio 03 Sep '11

03 Sep '11

Using a fairly simple dovecot config (which obviously needs some max limit tweaking) we have problems with IMAP synchronization between thunderbird clients. Two TB clients in the same IMAP mailbox will, from time to time, show different views of the same INBOX folders, when TB caching is enabled. The only fix is to right-click on the folder, go to "Properties" and use the "Repair Folder" option which repairs the local TB .msf cache file. Is there any server-side fix/workaround that would keep TB from regularly going out-of-sync ? This happens with TB3 and newer versions, in concert with either dovecot 1 or 2. The obvious fix is to disable TB local caching, which unfortunately also disables certain search features and can be a pain for large mailboxes. # dovecot -n # 2.0.13: /etc/dovecot/dovecot.conf doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (7168) doveconf: Warning: service anvil { client_limit=2048 } is lower than required under max. load (3075) # OS: OpenBSD 5.0 amd64 ffs auth_default_realm = dovecot.org auth_mechanisms = plain digest-md5 cram-md5 apop auth_username_translation = :@ default_client_limit = 2048 default_internal_user = _dovecot default_login_user = _dovenull default_process_limit = 1024 disable_plaintext_auth = no first_valid_gid = 125 first_valid_uid = 125 mail_location = maildir:/mail/%d/%n/ managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date mbox_write_locks = fcntl mmap_disable = yes passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_global_path = /etc/dovecot/default.sieve } protocols = imap pop3 lmtp sieve service auth { unix_listener auth-userdb { user = mail } } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } ssl_cert = </etc/balls/balls-cert.pem ssl_key = </etc/balls/balls-key.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = sieve } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep tb-lsub-flags mail_max_userip_connections = 50 } protocol pop3 { mail_max_userip_connections = 50 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_save_uidl = yes pop3_uidl_format = %v-%u }

[Dovecot] Control of \Seen flags dovecot 1.2.9
by Kristen J. Webb 03 Sep '11

03 Sep '11

Hi All, I have public mailboxes working with ACL's now, and I'm testing the ACL behavior. I've added lrws to two users so they can check off the messages they have read. I'm using CONTROL and INDEX in the location parameter for the namespace. It appears that if one user marks a message as read, all users see that message read. Is there any way to configure dovecot, so that each user maintains their own view of read messages? Relevant config (i think): namespace private { separator = / prefix = location = maildir:/home/vmail/%d/%n/Maildir:LAYOUT=fs inbox = yes } namespace public { separator = / prefix = Public/ location = maildir:/home/vmail/Public:LAYOUT=fs:CONTROL=/home/vmail/%d/%n/Maildir/Public:INDEX=/home/vmail/%d/%n/Maildir/Public subscriptions = no } -- Mr. Kristen J.

[Dovecot] Kerberos GSSAPI - proper item name in keytab
by Stanislav Klinkov 02 Sep '11

02 Sep '11

Hello, ALL. I am trying to organize a transparent single sign-on concept for my Active Directory users into Dovecot via IMAP. On the user's desktop I use Thunderbird 6.0 as a mail client (MUA), Windows XP as an operating system. Domain is controlled by Windows 2008 Server SP2 with Active Directory. I have installed on my Mail server Debian GNU/Linux 6.0.2 (Squeeze) and Dovecot 2.0.13 from official "wheezy" repositories of it with all dependencies. I ran into in a problem with generating proper "/etc/krb5.keytab" file for successful kerberos authentication against AD controller. I has performed all the steps described in official dovecot wiki here: http://wiki2.dovecot.org/Authentication/Kerberos I have generated a service ticket with name "imap/efim.test.local(a)MYORG.LAN" exactly as described in wiki. ("MYORG.LAN" is my kerberos realm.) But this does not work. I see in debug logs something like this: ******** main service logs ******** Aug 29 16:05:14 auth: Info: gssapi(?,192.168.4.12): While processing incoming data: Unspecified GSS failure. Minor code may provide more information Aug 29 16:05:14 auth: Info: gssapi(?,192.168.4.12): While processing incoming data: Wrong principal in request ************************************* ******** auth debug logs ********* Aug 29 16:05:14 auth: Debug: gssapi(?,192.168.4.12): Obtaining credentials for imap(a)efim.test.local Aug 29 16:05:14 auth: Debug: client out: CONT 1 Aug 29 16:05:14 auth: Debug: client in: CONT<hidden> Aug 29 16:05:16 auth: Debug: client out: FAIL 1 ************************************* But (!). If I define << auth_gssapi_hostname = "$ALL" >> instead of << auth_gssapi_hostname = efim.test.local >> then everything works fine. I decided to find out where is the problem, so I dig into source code of gssapi module, "mech-gssapi.c". For versions 2.0.13 and 2.0.14 of dovecot I see there the following: ********* mech-gssapi.c ********* static OM_uint32 obtain_service_credentials(struct auth_request *request, gss_cred_id_t *ret_r) /* blah-blah-blah */ principal_name = t_str_new(128); str_append(principal_name, service_name); str_append_c(principal_name, '@'); str_append(principal_name, request->set->gssapi_hostname); auth_request_log_debug(request, "gssapi", "Obtaining credentials for %s", str_c(principal_name)); inbuf.length = str_len(principal_name); inbuf.value = str_c_modifiable(principal_name); major_status = gss_import_name(&minor_status, &inbuf, GSS_C_NT_HOSTBASED_SERVICE, &gss_principal); ********************************* So, according to source code, Dovecot tries to find in krb5.keytab a principal named "imap@hostname". However wiki says to create the principal named "imap/hostname@REALM". Please, clarify where is the error: in source code, in wiki, or I have misunderstood something. Respectfully, Stanislav Klinkov.

[Dovecot] OT - small hd recommendation
by Daniel L. Miller 02 Sep '11

02 Sep '11

A little OT - but I've seen a few opinions voiced here by various admins and I'd like to benefit. Currently running a single combined server for multiple operations - fileserver, mailserver, webserver, virtual server, and whatever else pops up. Current incarnation of the machine, after the last rebuild, is an AMD Opteron 4180 with a Supermicro MB using ATI SB700 chipset - which means it supports SATA 3.0. Current storage is one o/s drive, and a 4-drive RAID10 array. The RAID10 is using the Linux softraid via mdadm. The drives are Seagates - ST3160811AS. So it's 320GB of storage, and SATA 1.5. I'm seeing some warnings & errors in my logs & dmesg - and Google tells me this can the result of several factors, including the hard drives. I haven't seen any SMART warnings as yet - but I am getting a little nervous and thinking about upgrading the storage. At this time, I'm just interested in recommendations for hard drives & partitioning strategy. At the time I created the RAID10 array - I was still in the early stages of learning these technologies (not that I know that much more now!) so I probably didn't take advantage of any of the advanced settings such as stripe size, cluster size, etc. I am using XFS. As part of the potential upgrade, I'm considering changing to RAID6 - seems a bit more efficient use of space. I see no reason for SSD - I think a set of reasonable 7200rpm drives should be just fine. What I don't know is, compared to my current 4 drive RAID10 with SATA 1.5, would even a single SATA 3 drive be comparable in terms of seek performance? Should I stick with the RAID-10? -- Daniel

[Dovecot] thunderbird and subscriptions with sieve
by Kristen J. Webb 02 Sep '11

02 Sep '11

Hi All, I'm a newbie trying to move mail out of my ISP onto a ubuntu (lucid) dovecot 1.2.9 server. Is there any way to automatically add folders created by sieve (GNU Mailutils 2.1) to the subscriptions file for a user? I'm currently testing spam, and if sieve created the folder with the first message, the thunderbird user does not see the new folder. Even more interesting, if the user then tries to create the Spam directory it thunderbird seems to quietly ignore the request and the user still cannot see the folder, but I digress... I can manually subscribe with thunderbird, but this won't scale for more complex sieve later by making the user responsible for finding everything. I can turn off subscription view in advanced settings on thunderbird, but we are trying to wean ourselves of of individual mail clients and I don't want to have to test this everywhere. Many thanks in advance! Kris -- Mr. Kristen J. Webb Teradactyl LLC. PHONE: 1-505-242-1091 EMAIL: kwebb(a)teradactyl.com VISIT: http://www.teradactyl.com Home of the True incremental Backup System

[Dovecot] Proprietary mail storage.
by Alex Cherniak 01 Sep '11

01 Sep '11

I have a large existing read-only collection of mails packaged in individual zip files as <rfc822 file>+<some additional info>. Is it possible (and how difficult) to create a proprietary plugin (like gzip) which will open a zip file, extract mail and pass it back to Dovecot? Where do I start? If plugin is not the right approach, what is? Another question is how will this affect Dovecot performance and how to avoid any significant degradation. Any help is appreciated.Thanks.

All mail sent to an alias-domain is delivered to the other domain. Quite easy if you've got postfixadmin already setup. Otherwise I think you could configure virtual_alias_maps in postfix to something like hash:virtual_domains virtual_domains: @example.net @example.com N.

[Dovecot] sorting order changed during migration from courier
by Micah Anderson 31 Aug '11

31 Aug '11

Hello, I've been working to migrate to dovecot (debian stable: 1:1.2.15-7) from courier (debian old-stable: 4.4.0-2). I've setup everything and migrated a test user over to the new system, and ran the courier-dovecot-migrate.pl script. The user is using alpine (the free version of pine) and their sort order changed on move to dovecot. Originally it was the default in alpine, which is to sort based on arrival. If he changes the sort order in alpine to sort based on date, then things are back to how he expects it. I noticed that there are no known issues with pine (http://wiki.dovecot.org/Clients#Pine) Ideally, I would prefer if all the users who are migrated aren't presented with a different sort order than they were used to, as the support burden will be quite high. What is it about this migration that could have caused that, and more importantly, how can I fix it? I moved the mail from the original system to this system via rsync -a. The old system was an i686 machine and ext3, this new one is amd64 and ext4. thanks for any ideas! micah # dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.2 protocols: imap imaps pop3 pop3s disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting: howdy, ready. login_processes_count: 10 login_max_processes_count: 256 first_valid_uid: 8 last_valid_uid: 8 first_valid_gid: 8 last_valid_gid: 8 mail_uid: 8 mail_gid: 8 mail_location: maildir:~/ maildir_copy_preserve_filename: yes maildir_very_dirty_syncs: yes mbox_write_locks: fcntl dotlock mail_executable(default): /maildir/postlogin_imap mail_executable(imap): /maildir/postlogin_imap mail_executable(pop3): /maildir/postlogin_pop mail_process_size: 512 mail_plugins(default): expire quota imap_quota mail_plugins(imap): expire quota imap_quota mail_plugins(pop3): expire quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): tb-extra-mailbox-sep delay-newmail imap_client_workarounds(imap): tb-extra-mailbox-sep delay-newmail imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)riseup.net auth default: default_realm: riseup.net verbose: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch dict: expire: mysql:/etc/dovecot/dovecot-dict-expire.conf --

[Dovecot] Multiple domains to one inbox and temporary redirects...
by Simon Brereton 31 Aug '11

31 Aug '11

Hi Can anyone point me to a howto to arrange for multiple domains to deliver to one inbox with Dovecot? For example, user1(a)example.com and user1(a)example.net should both be delivered to /var/spool/mail/virtual/example.net/user1 Currently, I have the dovecot LDA set as: dovecot unix - n n - - pipe flags=DRhu user=mailsystem argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} and in dovecot.conf: mail_location: maildir:/var/spool/mail/virtual/%d/%n For some domains only, I need to override that mail_location. Related to that, when user1 leave and user2 would like to receive user1's email, how can I get it so that email to user1(a)example.com is delivered to user2(a)example.com? Previously when I was using Postfix to deliver the mails, I could change the maildirloc in the DB - but I’m not sure how to accomplish this with dovecot LDA. Again, any pointers would be welcome. Thanks. Simon

Indexing mail attachments with Dovecot + Solr. This patch has been tested with these versions: * dovecot 2.0.9 * apache-solr 1.4.1 This is a patch for the fts-solr plugin (that indexes mail messages for Dovecot with Solr). In main stream, the plugin does not index attachments; With this patch, you can index mails and their attachments (pdf, docs, openoffice docs...) . You can get others goodies with this patch and the Solr Config provided, like Synonyms and Stemming (Spanish by default). Attachment indexing is provided by Solr Cell and Tika (ExtractingRequestHandler) * http://wiki.apache.org/solr/ExtractingRequestHandler Synonyms and Stemming are provided by SnowballPorterFilterFactory from Solr Language Analysis: * http://wiki.apache.org/solr/LanguageAnalysis We have tested Solr with Tomcat and Jetty. Tomcat is better to handle UTF-8 and bigger POSTS. Attachments file format supported * http://tika.apache.org/0.9/formats.html At present, attachments in attachments (like, for example, attachments in fordwarded "eml" attachments) are not indexed. Also, keep in mind that there are many types of files, and many variants of the same file type. Per Example, some pdf files are "not readable" by solr pdf reader. Config: There are two new options added to fts_solr property: * index-attachments Enable attachments indexing. * manual-update Avoid index on user search. You can trigger indexing using doveadm search or doveadm index commands. There is a new property for the section plugin to filter the mimetypes that you want to index. * fts_solr_mimetype files with this mimetype will be sent to solr. After integrating solr directory in your solr config, and building Dovecot with fts-solr support and with fts-solr-attachments-r885.patch applied, you can update your dovecot config by adding to your dovecot.conf: ... mail_pluings = $mail_plugins fts fts_solr plugin { fts = solr fts_solr = url=http://solrhost:8983/solr/ break-imap-search index-attachments fts_solr_mimetype = application/x-pdf application/vnd.openxmlformats-officedocument.wordprocessingml.document } ... -- Antonio Pérez-Aranda Alcaide aperezaranda(a)yaco.es Yaco Sistemas S.L. http://www.yaco.es/ C/ Rioja 5, 41001 Sevilla Teléfono +34 954 50 00 57 Fax +34 954 50 09 29

[Dovecot] auth: Error: LDAP: Connection lost to LDAP server, reconnecting
by Angel L. Mateo 31 Aug '11

31 Aug '11

Hello, I continue debugging my problems with my update to dovecot 2.x :-( I have dovecot 2.0.13 running in ubuntu 10.04 (lucid) x64. My users are in a ldap directory. The problem is that I have a lot of errors like: Aug 24 23:07:32 myotis28 dovecot: auth-worker(default): LDAP: Connection lost to LDAP server, reconnecting I have seen in the mail list a patch for 1.2 (http://hg.dovecot.org/dovecot-1.2/rev/355d5a40f7a7) to ignore these logs when the disconnection is because of idle timeouts. As far as I could see in this patch and 2.0.13 source code, this patch is already applied in 2.0. So I guess that the disconnection is for other problem, isn't it? -- Angel L.

[Dovecot] Sub-folder outside of the mail store
by Simon Brereton 30 Aug '11

30 Aug '11

Hi How do I create an IMAP folder that links to a folder outside of the mail store? For example, I have all domains under /var/spool/mail/virtual/domains.net/ and users under /var/spool/mail/virtual/domains.net/user Amavis delivers quarantine mail to /var/spool/mail/quarantine I would like one user (postmaster) to have a folder /var/spool/mail/virtual/domains.net/postmaster/.Quarantine and link it to that folder - is that possible? Is it safe? The client the postmaster uses can then reinject and deliver the mail if need be (i.e. it's safe or the attachment has been stripped). Thanks. Simon

[Dovecot] ldap authentication
by Daminto Lie 30 Aug '11

30 Aug '11

Hi, I have got Postfix, Dovecot IMAP and squirrelmail up and running on my ubuntu server 10.04 for a testing purpose. My question is in order to be able to login, do I need to create user accounts for each users on the server? I have about 20 users at the moment, and it's going to take time. I was thinking of using LDAP and have the dovecot authentication through LDAP. This way, I do not have to create accounts for 20 users on the server. The dovecot can just authenticate users by looking them up against the LDAP. I wonder if anyone would be able to share some guides as to how to set it up to work with Postfix and Dovecot. Thank you

[Dovecot] dovecot w/ libwrap on fbsd
by Gelu Lupas 30 Aug '11

30 Aug '11

Dovecot with libwrap doesn't work on FreeBSD for some reason or another. I have these lines in my /etc/hosts.allow: ALL: LOCAL 127.0.0.1: allow pop3: ALL: allow ALL: ALL: deny Yet when you try to telnet to localhost, port 110 this is what happens: Aug 29 22:48:38 dodo dovecot: pop3-login: Error: connect(tcpwrap) failed: Permission denied I also tried auth_debug=yes to see what's wrong but it only shows the processes which handled the connection, no extra info with the reason why it failed.

[Dovecot] : error while loading shared libraries: libdovecot.so.0 (arm cross compile)
by Stephen Feyrer 29 Aug '11

29 Aug '11

Hi. I've made a new attempt at build Dovecot. The build and then install processes appeared to work find. Then when I try to run Dovecot it reports the error: /share/MD0_DATA/optware/opt/sbin/dovecot: error while loading shared libraries: libdovecot.so.0: cannot open shared object file: No such file or directory To get a better idea of what's going on, I added --enable-devel-checks at ./configure and then ran gdb: # gdb --args dovecot -F GNU gdb 6.8 [snip] This GDB was configured as "arm-none-linux-gnueabi"... (no debugging symbols found) (gdb) run Starting program: /share/MD0_DATA/optware/opt/sbin/dovecot -F (no debugging symbols found) /share/MD0_DATA/optware/opt/sbin/dovecot: error while loading shared libraries: libdovecot.so.0: cannot open shared object file: No such file or directory Program exited with code 0177. (gdb) bt full No stack. (gdb) quit By the way on a separate but related note, adding --enable-maintiner-mode introduced a new problem also relating to libdovecot.so.0.0.0 I'll refer to that in the post script. # ls -alh

If I manually change the permission (to 0660) then I can see the mail in the MUA. If /var/spool/mail/virtual/domain.net/simon has 0770 permissions, the new mails should be delivered with 0660 permissions. (I don't remember if having g+s makes any difference in the directory like you have in the domain dir.) In any case, it would be better if mails were delivered as mailsystem:mailsystem 0600 since that's what you're reading them as. Unless you have some other good reason for requiring mailsystem group to be able to read them.

My guess is your delivering email with postfix to the inbox, instead of using dovecot-lda. And something odd is going on with that postfix to get odd permissions like that. You probably needed to edit the postfix virtual deliever transport, or maybe you just forget to active the dovecot-lda (deliever) transport.

[Dovecot] limiting number of incorrect logins per connection
by Alex 29 Aug '11

29 Aug '11

Hi Guys, Running Dovecot 2 on my server. It is regularly getting dictionary auth attacked. What I have noticed is that once connected to a pop3/imap login session, you can send endless incorrect usernames+passwords attempts. This is a problem for me... I use fail2ban to try and stop these script kiddies. The problem is that fail2ban detects the bad auths, firewalls the IP, however, since it's an "established" session, the attacker can keep authing away... It's only on a subsequent (new) connection that the firewalling will take effect. Why is there no configuration option such as "max auth attempts per connection"? This would be useful, so once the limit is reached, the connection is dropped. is there a patch/workaround?

Thanks to all who've made suggestions. It seems removing dotlocks as a locking method is the way to go. There is another dotlock locking variant mentioned in 10-mail.conf that seems to address this situation for those that can't get away from dotlocks: # dotlock_try: Same as dotlock, but if it fails because of permissions or # because there isn't enough disk space, just skip it. mbox_write_locks = dotlock_try fcntl Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] v2.0.14 released
by Timo Sirainen 29 Aug '11

29 Aug '11

http://dovecot.org/releases/2.0/dovecot-2.0.14.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.14.tar.gz.sig It's been a while since the previous release.. I've been a bit busy with my newly created Dovecot support company, but it was also summer and I wasted some time doing nothing useful. :) Most of my recent time has gone to adding new features to v2.1 branch. I'm planning on releasing v2.1.alpha1 somewhat soon and the final v2.1.0 sometimes later this year. This v2.0.14 release also contains one larger new feature: Ability to list and kick imap/pop3 proxy connections. This is done via a new "ipc" process where all proxying login processes connect to, which allows doveadm to communicate with them. If you're not using these features, this change (and its potential bugs) should be pretty much invisible. BTW. I know there are still mails I haven't read & replied to. I'll try to get to them eventually, but you may as well re-send anything you want me to read sooner rather than 6 months from now. Some of the largest changes since v2.0.13: + doveadm: Added support for running mail commands by proxying to another doveadm server. + Added "doveadm proxy list" and "doveadm proxy kick" commands to list/kick proxy connections (via a new "ipc" service). + Added "doveadm director move" to assign user from one server to another, killing any existing connections. + Added "doveadm director ring status" command. + userdb extra fields can now return name+=value to append to an existing name, e.g. "mail_plugins+= quota". - script-login attempted an unnecessary config lookup, which usually failed with "Permission denied". - lmtp: Fixed parsing quoted strings with spaces as local-part for MAIL FROM and RCPT TO. - imap: FETCH BODY[HEADER.FIELDS (..)] may have crashed or not returned all data sometimes. - ldap: Fixed random assert-crashing with with sasl_bind=yes. - Fixes to handling mail chroots - Fixed renaming mailboxes under different parent with FS layout when using separate ALT, INDEX or CONTROL paths. - zlib: Fixed reading concatenated .gz files.

[Dovecot] unlink_directory failed with 'Device or resource busy' on NFS
by 김기태 29 Aug '11

Hi, I'm getting some errors while I'm trying to move mailboxes from IMAP server to Outlook client. The error message is "IMAP command is failed" and I think it is useless. Here are the error messages written to server's syslog. imap(name(a)domain.com<mailto:name@domain.com>): Error: unlink_directory(/data/domain.com/name/INBOX/direct/.nfs00000000000033fd000… failed: Device or resource busy imap(name(a)domain.com<mailto:name@domain.com>): Error: unlink_directory(/data/domain.com/name/INBOX/IDC/.nfs000000000000709d000000… failed: Device or resource busy imap(name(a)domain.com<mailto:name@domain.com>): Error: unlink_directory(/data/domain.com/name/INBOX/OSSEC/.nfs000000000000709f0000… failed: Device or resource busy How can I solve this problem?

[Dovecot] Pop3 hanging up after login.
by Fabio Catunda 29 Aug '11

29 Aug '11

Hi, I'm trying to implement a second dovecot server on a second machine to try to load balance IMAP/POP3 services. The first machine is already running and is working pretty well with dovecot-pop3d 1:1.0.15-2.3+lenny1. The new machine is running dovecot-pop3d 1:1.2.15-7 and accessing the existing maildirs over a NFS share on /mnt/mail. When I try to telnet localhost 110 on the new machine it just freezes after the "pass MySecret", like this: # telnet localhost 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Bem Vindo. user my.user(a)mydomain.com.br +OK pass MySecret ... (Nothing else happens) If I try to stop Dovecot with /etc/init.d/dovecot stop it stops, but the pop3 process keep running and the only way to stop it is with kill -9. On my log I only can see this: Aug 27 15:03:40 radamante dovecot: auth(default): client in: AUTH#0112#011PLAIN#011service=pop3#011secured#011lip=127.0.0.1#011rip=127.0.0.1#011lport=110#011rport=60421#011resp=<hidden> Aug 27 15:03:40 radamante dovecot: auth-worker(default): pam(my.user(a)mydomain.com.br,127.0.0.1): lookup service=dovecot Aug 27 15:03:40 radamante dovecot: auth-worker(default): pam(my.user(a)mydomain.com.br,127.0.0.1): #1/1 style=1 msg=Password: Aug 27 15:03:42 radamante dovecot: auth-worker(default): pam(my.user(a)mydomain.com.br,127.0.0.1): pam_authenticate() failed: Authentication failure (password mismatch?)

[Dovecot] occasional dovecot crash, core captured but no symbol table info?

Re: [Dovecot] limiting number of incorrect logins per connection

Thanks for that. I will change it and recompile. Sorry for the grumpyness yesterday in my posts. Was having a bad day. Is there any chance of there being an option on future versions that allow a number of failed auth attempts to be specified before dropping the connection? The other thread you mentioned, I see someone devised a small patch in c to add this functionality. It didnt look like a lot of code to do it. What are your thoughts? ----- Reply message ----- From: "Timo Sirainen" <tss(a)iki.fi> Date: Sat, Aug 27, 2011 02:30 Subject: [Dovecot] limiting number of incorrect logins per connection To: "Alex" <alex(a)ahhyes.net> Cc: <dovecot(a)dovecot.org> login-common/client-common.h : #define CLIENT_LOGIN_TIMEOUT_MSECS (MASTER_LOGIN_TIMEOUT_SECS*1000) So set it to (45*60*1000) But I don't think there's much of a practical difference between these.

Re: [Dovecot] On IMAP vhost login, only Username being used
by hobie＠rumormillnews.com 26 Aug '11

26 Aug '11

Found it. :) Not a dovecot problem but a field in Icedove (Thunderbird variant) that had been automatically filled in by the software "to serve you better". It's on the Server Settings page as "User Name". "Never mind..." :) --hobie > Recapping: I'm working to set up Dovecot 2.0.13 along with some additional software (qmail, vpopmail, squirrelmail). It's working fine with squirrelmail now, but trying to connect over SSL with a Thunderbird variant and using IMAP, authentication fails because Dovecot is trying to match only the front part of the name (the user part), ignoring the domain name part of what it's being sent. So, instead of seeking to match virtual user: > > joe_blow(a)some_domain.com > > ...it's trying to match: > > joe_blow > > ...and failing, since joe_blow is not a system user but is a virtual host user. With Squirrelmail, connecting from localhost via non-SSL IMAP, the match is handled correctly, no problem. I've run the runtbird.sh script but no light was shed on this by the resulting output, all it said was that authentication was failing. > > Has anyone else encountered this problem? Any suggestions on how to fix it or where to look for additional info? Thanks kindly. > > --hobie > >> I tried the runtbird.sh script, hoping for more info - all it did was > show that auth is failing. I don't understand why Dovecot is separating the username from the domain name, and trying to match only on the username. Seems like there must be a config setting that affects this and that I'm overlooking. Thanks ahead for any help with this. >> >> --hobie >> >> hobie wrote earlier: >> >> ===== >> >> Attempting IMAP SSL login on new installation, using Icedove (Debain > Thunderbird variant), login fails.

[Dovecot] performance with 100k messages per folder
by Florin Andrei 26 Aug '11

26 Aug '11

dovecot-2.0-0.10.beta6.20100630.el6.x86_64 on CentOS 6. Virtual machine with 1 GB of RAM on VMWare. The configuration is more or less stock. Postfix receives then delivers to Dovecot. IMAP with mbox. Only one user account, but shared by several people via webmail (Roundcube webmail in Apache on the same machine). No other MUAs. 100k new messages per month, inbox is rotated monthly into a YYYYMM folder by a cron job. Only one monthly folder so far. Messages are never deleted (but I may start deleting old folders a year or two from now). This is mostly for reading, with occasional messages being forwarded. The email was pretty sluggish when logging in to the webmail interface. I asked the admin to increase the RAM from 0.5 to 1 GB. I changed mbox_very_dirty_syncs to yes. These measures seemed to accelerate it a lot. There's still a 1 sec pause when logging in, during which time the dovecot/imap process is using a lot of CPU. It looks like, as long as I give it enough RAM to keep the folders in memory, the whole thing should be fast enough, which is great. Any other tips-n-tricks to keep the email server speedy and the users happy? Should I worry about mbox_very_dirty_syncs as long as there are no other MUAs? -- Florin Andrei http://florin.myip.org/

[Dovecot] File Permissions and delivery
by Simon Brereton 26 Aug '11

26 Aug '11

Hi I'm very new to Dovecot (been using Courier for 5 years), but I've been persuaded of the merits of Dovecot and since the server needs upgrading that seems like the perfect time/excuse. On a test server, I set up postfix and installed Dovecot (running 32-bit Debian Squeeze, installed from apt-get). I mirrored the mail store (Maildirs, for historical reasons located under /var/spool/mail/virtual/domain.com/user). Then I ran the courier migration perl script and everything was fine and dandy. However, when I can to do the production migration, things weren't as smooth. The new server is 64-bit (not that I think it makes a difference, but if you're going to help me you should have all the information :) Again, I installed Postfix and Dovecot Took down the old server Mirrored the Maildirs Ran the migration script Restarted everything At this point everything looked like it was ok. Mail was being received and delivered to the Maildirs and the IMAP login was fine. However, I noticed errors in the logs when retreiving mail with the MUA along the lines of: Aug 26 16:59:48 mail dovecot: IMAP(simon(a)lydiard.net): open(/var/spool/mail/virtual/domain.net/simon/cur/1314328966.V801I166601bM7… failed: Permission denied (euid=999(mailsystem) egid=115(mailsystem) missing +r perm: /var/spool/mail/virtual/domain.net/simon/cur/1314328966.V801I166601bM756462.mail.net,S=2461:2,) After messing around with the chown and chmod (even though these were exactly the same as the test server) I finally discovered the issue. mail:~# ls /var/spool/mail/virtual/domain.net/simon/new/ -rwxrwx--- 1 postfix mailsystem 2.5K Aug 26 03:33 1314326000.V801I1666018M803015.mail.net,S=2461:2, -rwxrwx--- 1 postfix mailsystem 2.5K Aug 26 03:36 1314326209.V801I1666019M447273.mail.net,S=2460:2, -rw-rw---- 1 postfix mailsystem 2.5K Aug 26 04:00 1314327630.V801I166601aM308173.mail.net,S=2477:2, -rw------- 1 postfix mailsystem 2.5K Aug 26 04:22 1314328966.V801I166601bM756462.mail.net,S=2461:2, -rw------- 1 postfix mailsystem 1.1K Aug 26 16:28 1314372534.V801I166601cM615258.mail.net,S=1097:2, -rw------- 1 postfix mailsystem 1.1K Aug 26 16:31 1314372685.V801I166601dM264242.mail.net,S=1097:2, Mails are being delivered with 0600 permissions and not 0660 (the mails from courier seem to have all been 0770 as you can see). If I manually change the permission (to 0660) then I can see the mail in the MUA. After thinking for a while it occurred to me that this is covered in the LDA section. But making changes to the config file (either permissions or UID/GID) doesn't seem to make a difference. (Yes, I did restart postfix and dovecot after the changes). Anyway, here is my dovecot -n: mail:~# dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.2 ext3 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_ca_file: /etc/ssl/keys/ca.crt ssl_cert_file: /etc/ssl/keys/mail.net.crt ssl_key_file: /etc/ssl/private/mail.net.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mailsystem mail_location: maildir:/var/spool/mail/virtual/%d/%n maildir_very_dirty_syncs: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh lda: postmaster_address: postmaster@net mail_plugins: quota log_path: info_log_path: deliver_log_format: msgid=%m: %f: %$ auth default: mechanisms: plain login user: mailsystem verbose: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch userdb: driver: static args: uid=999 gid=115 home=/var/spool/mail/virtual/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: mailsystem master: path: /var/run/dovecot/auth-master mode: 432 user: mailsystem group: mailsystem plugin: quota: maildir As you can see, I tried to go 0660 in both client and master.

Hi, I saw that thread already, however it does not offer any solution that can be applied to dovecot directly. That thread has also been asleep for well over a year.

Re: [Dovecot] On IMAP vhost login, only Username being used
by hobie＠rumormillnews.com 26 Aug '11

26 Aug '11

Recapping: I'm working to set up Dovecot 2.0.13 along with some additional software (qmail, vpopmail, squirrelmail). It's working fine with squirrelmail now, but trying to connect over SSL with a Thunderbird variant and using IMAP, authentication fails because Dovecot is trying to match only the front part of the name (the user part), ignoring the domain name part of what it's being sent. So, instead of seeking to match virtual user: joe_blow(a)some_domain.com ...it's trying to match: joe_blow ...and failing, since joe_blow is not a system user but is a virtual host user. With Squirrelmail, connecting from localhost via non-SSL IMAP, the match is handled correctly, no problem. I've run the runtbird.sh script but no light was shed on this by the resulting output, all it said was that authentication was failing. Has anyone else encountered this problem? Any suggestions on how to fix it or where to look for additional info? Thanks kindly. --hobie > I tried the runtbird.sh script, hoping for more info - all it did was show that auth is failing. I don't understand why Dovecot is separating the username from the domain name, and trying to match only on the username. Seems like there must be a config setting that affects this and that I'm overlooking.

[Dovecot] Dovecot 2.0.13 How to use POP3 order
by Nick Celebic 26 Aug '11

26 Aug '11

I saw a few commits for 2.0.13 that added MAIL_FETCH_POP3_ORDER, but I haven't been able to find any information on how to use it. I'm migrating from a Merak mail server into dovecot and all the email can be copied directly into a Maildir/cur directory. The filenames are just the timestamps. When I check with dovecot pop3, they seem to be randomly ordered. I'm hoping this provides a solution where it will look at the file list or stat order. If this isn't possible, can someone tell me how I can change the order in which dovecot lists mails in a UIDL in POP3? Thanks, Nick Celebic

[Dovecot] Catch22: user needs space to fix out of space condition
by Joseph Tam 25 Aug '11

25 Aug '11

A mail user reported that he filled up his INBOX (despite reminders he was approaching his filesystem quota), and furthermore, he could not fix the situation because he couldn't expunge message he marked for deletion. The dovecot logs revealed the cause dovecot: imap(user): Error: open(/var/mail/user.lock) failed: Disc quota exceeded This created an impasse where a user cannot free space because he needs to create a lock file that cannot be created because he needs free space. Is there any way out of this without administrator intervention? Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] dovecot and maillists problem
by Костырев Александр Алексеевич 25 Aug '11

25 Aug '11

Hello there! I have a little trouble with using dovecot as lmtp and maillists. I use dovecot 2.0.13 with exim 4.72 on Debian 6.0. (All stuff at one host). info of maillists is store in mysql table, for example: +---------+-------------------------------------------------------------------------------------------------+ | name | recipients | +---------+-------------------------------------------------------------------------------------------------+ | Hab_Tax | 2504000067-253601001.253809737993@25.example.org,2721097514-272101001.271300057673@.example.org | +---------+-------------------------------------------------------------------------------------------------+ The problem is: When I send a letter to short maillist (as above) it get the same ID and stored only once in the maildir of one user who is the member of that maillist - that's ok, but When I send a letter to maillist with a large number of recipients it occurred that it's saved more than one, because of the headers added by dovecot lmtp (I've changed host name): diff letter_in_one_user/1314238006.M841940P6916.pink\,S\=12778136\,W\=12953189 letler_in_second_user/new/1314237993.M460165P6916.pink\,S\=12778136\,W\=12953189 3,4c3,4 < by pink.atlas-2.ru (Dovecot) with LMTP id 6UiGJBWuVU4EGwAA1nFjLA < ; Thu, 25 Aug 2011 13:06:46 +1100 --- > by pink.atlas-2.ru (Dovecot) with LMTP id VUeGJBWuVU4EGwAA1nFjLA > ; Thu, 25 Aug 2011 13:06:29 +1100 It's the same letter accept the date and id.

[Dovecot] Post-login scripting with virtual users
by Mark Willcox 25 Aug '11

25 Aug '11

I am running Dovecot 2.0.13 on Fedora 15. I have migrated from a bincimap installation using checklocalpwd. All email is in folders owned by a unprivileged user, popuser. The email users are entirely virtual and have no relationship to actual linux users. My userdb calls return the UID and GID of popuser and all goes well retrieving the mail via POP3 and IMAP. I am trying to implement a Post-login script to register the IP address that the authentication came from. Dovecot seems to be trying to execute the script as the email non-user, which does not work. I have specified that the script should be run as popuser, but it still runs as devnull(a)dhzone.com for instance. Everything up top that point seems to be happening happily under popuser. I added a "user = popuser" directive and it had no effect that I could see. I know that dovecot read the directive because I changed it to "user = 555" and dovecot would not run because "555" is not a user. I tried adding a "User = popuser" within the unix_listener but that also had no effect. Any ideas? Thank you! ------------------------------ Here is my dovecot -n: # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.40.3-0.fc15.x86_64 x86_64 Fedora release 15 (Lovelock) auth_debug = yes disable_plaintext_auth = no mail_debug = yes mbox_write_locks = fcntl passdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } protocols = imap pop3 service imap-postpop { executable = script-login /usr/local/bin/set_postpop unix_listener imap-postpop { } user = popuser } service imap { executable = imap imap-postpop } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } ----------------------------------------------------- The dovecot-sql.conf.ext looks like this: driver = mysql connect = host=localhost dbname=webmail user=xxxx password=xxxx password_query = SELECT id AS user, IF( clear IS NULL, CONCAT('{CRYPT}',crypto), CONCAT('{PLAIN}',clear)) AS password \ FROM users WHERE id = '%u' user_query = SELECT home, uid, gid \ FROM users WHERE id = '%u' ------------------------------- >From the maillog: Aug 24 13:01:57 callisto dovecot: auth: Debug: client out: OK#0111#011user=devnull(a)dhzone.com Aug 24 13:01:57 callisto dovecot: auth: Debug: master in: REQUEST...

[Dovecot] Dovecot rejecting Vpopmail User 89
by hobie＠rumormillnews.com 24 Aug '11

24 Aug '11

I'm working to get Dovecot 2.0.13 working along with qmail, Vpopmail and Squirrelmail on a Debian 6.0.2 system, Dovecot compiled, not from a package. Vpopmail has a widely known assigned user/group ID of 89 and is the owner of all the mail folders. Regardless of value of first_valid_uid (1, 89, other), Dovecot denies Squirrelmail connection, saying it can't allow access to UID 89. "Couldn't drop privileges", it says. I'd be grateful for fixes, suggestions, or a pointer to an existing answer to this problem. Thanks ahead. :) Presently dovecot -n shows: # 2.0.13: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.2 ext3 auth_debug = yes disable_plaintext_auth = no mail_debug = yes mail_location = maildir:/home/vpopmail/domains/%d/%n/Maildir maildir_very_dirty_syncs = yes passdb { driver = vpopmail } protocols = imap pop3 ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } userdb { args = quota_template=quota_rule=*:backend=%q driver = vpopmail } --hobie

Enable auth_verbose and check the logs. But I'm pretty sure that means Dovecot can't change to the Maildir folder. I assume the user's folder is owned by vpopmail:vchkpw?

[Dovecot] BUG - lmtp multiple recipients fail - setuid issue?
by Boris Lordis 24 Aug '11

24 Aug '11

Hello, I am not having much luck on this particular issue so I wanted to make sure that this is registered as a potential bug. The essence of the problem is that for a given message addressed to multiple users, lmtp writes the message correctly to the first addressed user only, then subsequent user writes fail as the lmtp process doesn't run with the proper permissions and tries to link files from different users as part of its message writing. Below you can see that lmtp (running with steve's id, who was the first listed recipient) is trying to link a file in jerry's inbox meeting with failure: Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Error: link(/spool/mail/j/jerry/mail/INBOX/u.20423, /spool/mail/s/steve/mail/INBOX/.temp.1311791081.P12412Q2M989550.testmailserver.) failed: Permission denied Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): +1IXBeVXME58MAAARoVNxQ: msgid <201107271824.p6RIOPa5020900 at backup.>: save failed to INBOX: Internal error occurred.

If I send an attchment between two accounts on my test system, the attment gets saved ion the configured mail_attachment_dir. But... if I delete it from the senders Send folder and the receivers Inbox (and of course empty Trash afterwards in both cases), the hashes and the attachment are not deleted in mail_attachment_dir (as I would expect). Is this a bug, or have I misunderstood the concept of storing attachments?

[Dovecot] Cannot delete subfolder in public folder
by Karsten Becker 24 Aug '11

24 Aug '11

Hi there, I have the problem that I'm unable to delete a subfolder (again) I created within a public folder. I've already read about configuring Thunderbird to delete immediately - which I did. But it still doesn't work. I delete -> the folder is gone -> I get a TB error message saying "The folder doesn't exist" -> after restarting TB the folders appear again. Maybe someone has a hint. My tip is that I may have a wrong understanding of the ACL mechanism... :-( Regards from Berlin/Germany Karsten ------------------------ Log: > Aug 24 00:01:37 mail01 dovecot: imap(karsten.becker(a)company.eu): Debug: acl vfile: file /etc/dovecot/global-acls//.DEFAULT not found > Aug 24 00:01:37 mail01 dovecot: imap(karsten.becker(a)company.eu): Debug: acl vfile: file /srv/vmail/user-mailboxes/company.eu/karsten.becker/mailboxes/dovecot-acl not found > Aug 24 00:01:37 mail01 dovecot: imap(karsten.becker(a)company.eu): Debug: acl vfile: file /etc/dovecot/global-acls/Folders/test01/aaa not found > Aug 24 00:01:37 mail01 dovecot: imap(karsten.becker(a)company.eu): Debug: acl vfile: reading file /srv/vmail/public_folders/test01/aaa/dovecot-acl Here's the filesystem structure in /srv/vmail: > root@mail01.compdmz.local:/srv/vmail# ls -l public_folders/test01/ > total 20 > drwxr-xr-x 5 vmail vmail 4096 2011-08-23 23:50 aaa > drwxr-xr-x 2 vmail vmail 4096 2011-08-23 21:45 cur > -rw-r--r-- 1 vmail vmail 25 2011-08-23 22:19 dovecot-acl > drwxr-xr-x 2 vmail vmail 4096 2011-08-23 21:45 new > drwxr-xr-x 2 vmail vmail 4096 2011-08-23 21:45 tmp > root@mail01.compdmz.local:/srv/vmail# Here's the content of dovecot-acl (there are another ones in subfolder aaa with the same content, inherited during creation): > authenticated lrwstipekx Here's my configuration of Dovecot: > # 2.0.13: /usr/local/dovecot-2.0.13/etc/dovecot/dovecot.conf > # OS: Linux 2.6.32-33-server x86_64 Ubuntu 10.04.3 LTS ext4 > doveconf: Warning: Dovecot was last started using /etc/dovecot/dovecot.conf, but this config is /usr/local/dovecot-2.0.13/etc/dovecot/dovecot.conf > auth_cache_negative_ttl = 0 > auth_cache_size = 10 M > auth_mechanisms = plain login > base_dir = /usr/local/dovecot/var/run/dovecot > dict { > acl = mysql:/etc/dovecot/dovecot-dict-shared-mailboxes-mysql.conf > expire = mysql:/etc/dovecot/dovecot-dict-expire-mysql.conf > quota = mysql:/etc/dovecot/dovecot-dict-quota-mysql.conf > } > log_timestamp = "%Y-%m-%d %H:%M:%S " > login_greeting = Company Institute > mail_attachment_dir = /srv/vmail/attachments > mail_attachment_hash = %{sha256} > mail_cache_min_mail_count = 2 > mail_debug = yes > mail_location = mdbox:/srv/vmail/user-mailboxes/%d/%n > mail_plugins = acl expire quota > mailbox_idle_check_interval = 1 mins > namespace { > inbox = yes > location = > prefix = > separator = / > subscriptions = yes > type = private > } > namespace { > list = children > location = mdbox:/srv/vmail/user-mailboxes/%%d/%%n > prefix = Users/%%d/%%n/ > separator = / > subscriptions = no > type = shared > } > namespace { > list = children > location = maildir:/srv/vmail/public_folders:INDEX=/srv/vmail/user-mailboxes/%d/%n/public_folders-seen:LAYOUT=fs > prefix = Folders/ > separator = / > subscriptions = no > type = public > } > passdb { > args = /etc/dovecot/dovecot-mysql.conf > driver = sql > } > plugin { > acl = vfile:/etc/dovecot/global-acls:cache_secs=300 > acl_shared_dict = proxy::acl > expire = Trash > expire2 = Trash/* > expire3 = Junk > expire4 = Junk/* > expire_dict = proxy::expire > quota = dict:User quota::proxy::quota > quota_rule = *:storage=10485760 > quota_rule2 = Trash:storage=+1048576 > quota_warning = storage=95%% quota-warning 95 %u > quota_warning2 = storage=80%% quota-warning 80 %u > } > postmaster_address = postmaster(a)company.eu > protocols = imap pop3 > service auth { > unix_listener /var/spool/postfix/private/auth_dovecot { > group = postfix > mode = 0660 > user = postfix > } > unix_listener auth-master { > mode = 0600 > user = vmail > } > user = root > } > service dict { > unix_listener dict { > mode = 0600 > user = vmail > } > } > service imap-login { > inet_listener imaps { > port = 993 > ssl = yes > } > process_min_avail = 2 > } > service imap { > vsz_limit = 512 M > } > service pop3-login { > inet_listener pop3s { > port = 995 > ssl = yes > } > } > service quota-warning { > executable = script /usr/local/bin/quota-warning.sh > user = vmail > } > ssl = required > ssl_cert = </etc/postfix/ssl/mail01.compdmz.local.crt > ssl_key = </etc/postfix/ssl/mail01.compdmz.local.key > userdb { > args = /etc/dovecot/dovecot-mysql.conf > driver = sql > } > verbose_proctitle = yes > protocol lda { > auth_socket_path = auth-master > postmaster_address = postmaster(a)company.eu > } > protocol imap { > imap_client_workarounds = delay-newmail > imap_max_line_length = 128 k > mail_plugins = acl expire quota imap_acl imap_quota > } > protocol pop3 { > pop3_client_workarounds = outlook-no-nuls oe-ns-eoh > }

[Dovecot] acl with hierarchy separators mismatched config
by YAEGASHI Takeshi 24 Aug '11

24 Aug '11

Hi there, I'm testing dovecot 2.0.13 on Debian squeeze (deb from http://xi.rename-it.nl/debian) with the following doveconf -n. -------- # 2.0.13 (1449a2e2c1f5): /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-openvz-amd64 i686 Debian 6.0.2 first_valid_uid = 8 mail_debug = yes mail_location = maildir:~/Maildir mail_plugins = listescape mail_log notify acl namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = children location = maildir:/var/mail/public:INDEX=~/Maildir/public prefix = Public/ separator = / subscriptions = no type = public } passdb { driver = pam } plugin { acl = vfile } protocols = " imap" ssl = no userdb { args = uid=mail gid=mail home=/var/mail/private/%u driver = static } protocol imap { mail_plugins = listescape mail_log notify acl imap_acl } -------- My primary interest is acl and listescape enabled folders in the public namespace. I've chosen "/" as the hierarchy separator to support folder names with dots ("."). /var/mail/public is a maildir with the maildir++ layout where the separator is a dot ("."). So I set up intial acls and folders as follows: -------- # mkdir /var/mail/public # echo 'anyone lra' >/var/mail/public/dovecot-acl # maildirmake.dovecot /var/mail/public/.aaa # echo 'anyone lrwstipekxa' >/var/mail/public/.aaa/dovecot-acl # chown -R mail.mail /var/mail/public -------- But my attempt to create a mailbox under Public/aaa fails with "Permission denied". -------- # imtest -a yaegashi localhost S: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready.

NO Invalid mailbox name: Public/aaa/cur -------- Is this behavior expected? Misconfiguration or dovecot bug? I prefer the maildir++ layout with listescape as it's reserved-folder-name free (eg. cur new tmp). Regards, -- YAEGASHI Takeshi <yaegashi(a)debian.org>

[Dovecot] LDA and auth-userdb socket permissions
by a.smith＠ukgrid.net 24 Aug '11

24 Aug '11

Hi, just wanted to check this as the wiki seems to have contradictory information. With respect to running the LDA as multiple UIDs the wiki says: [QUOTE]If you're using more than one UID for users, you're going to have problems running dovecot-lda, as most MTAs won't let you run dovecot-lda as root[/QUOTE] But in the example for the config file the text reads: [QUOTE] service auth { unix_listener auth-userdb { mode = 0600 user = vmail # User running dovecot-lda #group = vmail # Or alternatively mode 0660 + dovecot-lda user in this group } } [/QUOTE] So it says you can stick the LDA user just in the (vmail or whatever) group and that is enough. So you aren't restricted to a single UID for access anymore... I tested this and the later did not work, that is if I put my LDA user in the group for the auth-userdb socket with permissions 0660 I got an error back from dovecot saying that the owner was incorrect. So, as it stands I guess the bit about setting group should be removed from the wiki? Secondly, why doesn't this currently work? Why is the owner all important? thanks Andy.

[Dovecot] dovecot and tcpwrappers
by Kees Lemmens 23 Aug '11

23 Aug '11

Hi, I used dovecot 1.x for quite a while and it worked fine. However, I used it through inetd and used hosts.allow/deny to restrict access to only certain groups of systems. Since yesterday I have dovecot 2.0.13. But in version 2.0.13 it seems that starting using inetd doesn't work anymore : I only get a strange error message if I try to connect using telnet : telnet localhost imap doveconf: Fatal: execvp(imap-login) failed: No such file or directory I tried a lot of things but couldn't get it going over inetd so I decided to start it directly using an init script, also because you say in the wiki this is (now) the preferred method. That indeed works fine, but I realised today that dovecot is now completely ignoring all my hosts.allow/deny settings and so is worldwide accessible ! Is dovecot indeed ignoring hosts.allow/deny ? And if so, how can I have the same amount of protection as I previously had with dovecot 1.x over inetd ? BTW: I tried to post on the mailinglist but it seems I can't access them it the moment, altough I did subscribe and login. Is there anything wrong ? Thanks for your reply ! -- With best regards, Kees Lemmens. ----------------------------------------------------------------------- Delft Institute of Applied Mathematics (DIAM), Faculty Electrical Engineering, Mathematics and Computer Science, Delft University of Technology, Delft, The Netherlands,

[Dovecot] zlib plugin doesn't read concatenated .gz mailbox
by Dmitry Nezhevenko 23 Aug '11

23 Aug '11

Hi, I've observed that dovecot doesn't displays all mails from compressed via gzip mailbox (mbox). At the same time "mutt -f mailbox.gz" displays it correctly with all messages. I'm using archivemail to archive old mails. Internally it creates new "gzip" archive with "expired" messages and then concatenates it with archive. The easiest way to reproduce it without archivemail is to create two mailboxes, gzip them independently and then concatenate to one gzip archive. mutt, gunzip and other tools understands such archives. Also I've shared such mbox: http://dion.org.ua/uploads/2011/07/dovecot_test_gzip.gz It should contains ~20 messages. dovecot will "see" only two first. PS. % sudo dovecot --version 2.0.13 -- WBR, Dmitry

[Dovecot] dovecot's documentation dearth
by Postmaster 23 Aug '11

23 Aug '11

Hello. The first thing for me to say is thanks! I've been using dovecot since test 61 and it has basically performed flawlessly for me from day number 1. Dovecot makes me look like a genius sysadmin, especially compared to my colleagues struggling with exchange. So thanks, gracias, obrigado!! I'm working on a configuration for 2.0 and I'm finding the documentation somewhat difficult. I think it would be very helpful to me to have encountered a single page that detailed all available configuration sections. I don't know how to find out what the sections are, when to use them or what specifically they control. So far I've encountered... passdb plugin service protocol userdb local_name (and I think there is another one of these for ips) The service section itself would benefit from a single page detailing all of the possible types of service sections available. The next problem I've had is discovering that several parts of dovecot have no documentation at all even though they are standalone executables run by root. config, log, and ssl_params all run as root but there is also anvil and they look to me like they could support listening on a port if inet_interfaces is defined. You can say, "Relax fella, trust me. These programs are all part of dovecot and are run only if they're needed." Then I'll say, "Yes but I'm the administrator. I need to know how the parts fit together to know if the system's broken." Then you say, "Well that makes sense, but the things you're talking about aren't really configured. They are mostly internal to dovecot, they just happen to be broken out into external programs. You may as well be asking for documentation on a specific function in a library. If that's what you want, you can read through the source code." Well I guess that would be one solution. The bottom line is that it gives me an uncomfortableness to not be able to control or explain the operation of the software I'm supposedly administering. Take the program named log (which should be named dovecot-log or something less generic), it is launched even though I've specified syslog in the configuration. Logging is not interrupted when the process is killed. So, why is it running? What is it doing? Why does it need root? How do I control it? I think these are all good questions for an administrator to ask. That's my feedback for what it's worth, but mostly, thanks again for dovecot!

[Dovecot] Default and per-User sieve script
by Patrick Westenberg 23 Aug '11

23 Aug '11

Hi guys, is there any way to configure Dovecot to process the default sieve script and, after that, a user specific script? I have a default script to sort spam into a spam folder but if a user specific script is present, the default script is ignored. sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_global_path = /usr/local/etc/dovecot/sieve/default.sieve Regards Patrick

[Dovecot] dovecot deadlock with procmail
by kunal verma 23 Aug '11

23 Aug '11

I m using dovecot 1.0.7. I m having problems in mail delivery to my mail server locally. When a user sends a mail few mails are in mail Q for longer period of time. The local delivery agent(*procmail*) is trying to deliver the mail at regular interval but it is unable to deliver. But as soon as I *restart* *dovecot* the mails in the Q are delivered immediately. I suspect it is because of locking of *mbox* file of users by dovecot. How to overcome this problem as mails are some mails are taking hours to be delivered?? please let me know the solution.

[Dovecot] Large Mailbox Slow
by Matt 23 Aug '11

23 Aug '11

Doubt if there is any answer to this but will ask anyway. Have a few pop3 accounts with thousands of messages. Its slow when checking email naturally. Are there any tweaks to speed it up? I imagine there is an exchange of the message and header list which is the slow down. Too bad the list could not be compressed with gzip or something first. I think http has an option similar to that. Just asking.

[Dovecot] Dovecot Postfix and ssl_require_client_cert
by mezzo 23 Aug '11

23 Aug '11

Hi, I have a working mail system with postfix 2.7 and dovecot 1.2.15. I use secure connections for imap and smtp. When I try to use client certificate authorisation I have some problems. As soon as I enable the dovecot feature ssl_require_client_cert I have to present a valid certificate to receive or send email. Receiving emails works fine, but I can not send emails any more. The only way I could get this to work was to disable smtpd_sasl_auth_enable so postfix did not tries to get authorisation from dovecot. This way I can not have sasl authorisation for localnet and client certificate authorisation from extern. The reson seams to be that postfix does not sent the valid-client-cert along with the other parameter that are needed to satisfy the auth-process of dovecot. I found a few threads from 2008 where this problem is discussed but without a final solution. Is there a way to enable ssl_require_client_cert in dovecot and have smtpd_sasl_auth_enable=yes in postfix? Better would be a way to tell dovecot only to use ssl_require_client_cert during the imap autorisation. I did not get it to work. I miss something?

[Dovecot] Update indexes with dovecot 1.1
by Angel L. Mateo 23 Aug '11

23 Aug '11

Hello, I have a farm of dovecot 1.1 servers (debian lenny). Mailboxes are in Maildir format. Is there any way to manually update indexes? Does it worth? I mean... Our problem is that mail is delivered via dovecot lda, but, because we have a farm of servers, we don't guarantee that mail is delivered through the same server that the user is using for his imap connection, so the imap server could have this index unupdated. So I want to force an update (or at least nearly updated) in order to have the index updated in all servers at the time the user get to work. -- Angel L.

[Dovecot] Disconnected: Too many invalid IMAP commands
by Steve Fatula 23 Aug '11

Using current Apple mail 4.5 as client to Dovecot 2.0.13 I see lots of these messages in the log file for one machine and account. Near as I can tell, the client still works (it's mine), but, the messages concern me. Is there some known issue with Apple mail, or, if not, how to capture the information needed to debug? Sample log entires for my user matching on the message: Aug 20 16:28:36 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=3242/14672 Aug 20 16:28:43 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=14219/231327 Aug 20 16:29:50 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=640/1968 Aug 20 16:29:57 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=3521/2024 Aug 20 16:30:04 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=6690/3415 Aug 20 16:30:05 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=5098/15294 Aug 20 16:30:06 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=706/15684 Steve

[Dovecot] Duplicate Email with Dovecot Sieve
by Holden Hao 22 Aug '11

22 Aug '11

I am trying to use Dovecot Sieve after upgrading Dovecot from 1.0.15 to 1.2.17. I used the same config file from the old version but I added some entries to make sieve work. In my initial tests, sieve works and is able to do the actions that I set it to do. However, I get 2 copies of incoming emails. The inbox would always preserve a copy even if the sieve filter is set to transfer emails to another folder or redirect it to another address. The logs do not seem to report any issues. I don't know what causes the problem and I would appreciate some pointers. Here are some more details of my setup: OS: Linux 2.6.24.2 Dovecot: 1.2.17 Dovecot Sieve:0.1.19 Manage Sieve:0.11.13 MTA: Qmail 1.03 dovecot -n ---------------------------------------------------------------------------- # 1.2.17: /usr/local/etc/dovecot.conf # OS: Linux 2.6.24.2 i686 Debian lenny/sid log_path: /var/log/dovecot.log log_timestamp: protocols: imap pop3 imaps pop3s managesieve ssl_cert_file: /var/dir/etc/certificates/server.crt ssl_key_file: /var/dir/etc/certificates/server.key disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login login_greeting: Welcome login_process_size: 32 verbose_proctitle: yes first_valid_uid: 1000 mail_location: maildir:~/Maildir mail_debug: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve imap_client_workarounds(default): outlook-idle imap_client_workarounds(imap): outlook-idle imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v pop3_uidl_format(managesieve): %08Xu%08Xv managesieve_logout_format(default): bytes=%i/%o managesieve_logout_format(imap): bytes=%i/%o managesieve_logout_format(pop3): bytes=%i/%o managesieve_logout_format(managesieve): bytes ( in=%i : out=%o ) namespace: type: private separator: . prefix: INBOX. location: maildir:~/Maildir inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)xxxxxxxxxx.org mail_plugin_dir: /usr/local/lib/dovecot/lda mail_plugins: quota sieve sendmail_path: /var/qmail/bin/sendmail log_path: /var/log/dovecot-deliver-errors.log info_log_path: /var/log/dovecot-deliver.log auth default: verbose: yes passdb: driver: checkpassword args: /var/qmail/bin/auth_pop userdb: driver: prefetch plugin: quota: maildir sieve: ~/.dovecot.sieve sieve_dir: ~/sieve -------------------------------------------------------------------- from: dovecot-deliver.log -------------------------------------------------------------------- deliver(user): Info: Loading modules from directory: /usr/local/lib/dovecot/lda deliver(user): Info: Module loaded: /usr/local/lib/dovecot/lda/lib10_quota_plugin.so deliver(user): Info: Module loaded: /usr/local/lib/dovecot/lda/lib90_sieve_plugin.so deliver(user): Info: Quota root: name= backend=maildir args= deliver(user): Info: Namespace: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=1, subscriptions=yes deliver(user): Info: maildir: data=/home/user/Maildir deliver(user): Info: maildir++: root=/home/user/Maildir, index=, control=, inbox=/home/user/Maildir deliver(user): Info: sieve: using sieve path for user's script: /home/user/.dovecot.sieve deliver(user): Info: sieve: opening script /home/user/.dovecot.sieve deliver(user): Info: sieve: executing compiled script /home/user/.dovecot.sieve deliver(user): Info: sieve: msgid=< CAJNnNYmQpmEopFfT3+_qHvXYxf3v-4bzv9ojJqGfRtcddnTg8g(a)mail.gmail.com>: stored mail into mailbox 'Inbox.Test' Thanks in advance for your replies.

[Dovecot] Dovecot 1.2.16 and Thunderbird 5 - pop3 mails not getting deleted
by Ian Evans 22 Aug '11

22 Aug '11

I run a Dovecot 1.2.16 pop3 server and have just started using the Thunderbird 5 email client. Thunderbird is set to leave the messages on the server unless they are over 91 days old. However, I'm not seeing it delete any of the older messages. I'll run a debug run of Thunderbird when I get back home, but I'm just wondering if there's any gotcha's I should be aware of with Thunderbird and Dovecot in a pop3 environment. The Thunderbird folks are wondering if it's the server not the client. Thanks.

Upgrading to Dovecot2 would allow you to solve this in various ways: - use "doveadm force-resync" - user director to bind to a particular server You could put the indices on a shared filesystem. If neither an update nor shared indices are feasible, maybe you can enable the master user feature, and run a script that logs in as each user and do an IMAP operation that will force a resync of the INBOX indices. For example, # On IMAP server with a localhost interface for u in $users; do echo "1 login $u*master masterpw\n2 SELECT INBOX\n3 logout" | \ nc 127.0.0.1 143 done Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Sharing all mailboxes and userdb LDAP attrs
by Felipe Scarel 19 Aug '11

19 Aug '11

Hello all, I'm setting up a Dovecot environment here, version 1.2.15 on Debian 6.0.2 "squeeze". This is actually a complete revamp of the previous setup we have in-place here, built from the ground up with updated versions of all involved software. The operators have told me that they use some scripts hacked up by a previous sysadmin to give a single "admin" account full access to all user mail. That is, if any user runs into problems, they: 1. Call in; 2. The operator logs in as the admin user; 3. Operator performs maintenance duties on user email. I've been researching the possibility of using Dovecot shared namespaces to perform that very same task in a better fashion in this new server. So far, I've been able to globally share users' INBOXes and view them from a single admin account (through user= entries on global acl's). My ultimate goal, however, is to have access to all user mailboxes with any user that's a member of a particular group, adding all operators to that group as needed. - - - - - First question, then, is this one: how can I give global access to all user mailboxes? I've read that it's possible to give access to all subfolders of a particular folder throught the use of a .DEFAUL acl. That didn't seem to work with the uppermost directory, however. Here's what I tried: root@mail:/etc/dovecot# dovecot -a | grep acl: acl: vfile:/etc/dovecot/acl:cache_secs=300 root@mail:/etc/dovecot# cat acl/.DEFAULT owner lrwstipekxa user=admin lrwstipekxa Renaming .DEFAULT to INBOX does achieve the intended goal, but only for the INBOX folder evidently. - - - - - Second question is somewhat simpler. So far I've been using a single admin user, but I'd like to switch to using an admin group in the future. I've read that the best way to do that would be to use the user_attrs entry in my dovecot-ldap.conf file, while using a userdb ldap. The groups should be strings separated by commas in the appropriate attribute, from what I understand. Is there any readily-available or recommended schema I can use to fill up that attribute? I'm using the default ones (plus samba.schema) but I've seen mostly space to fit GID's, not group names. Thanks in advance, fbscarel PS: Here's my dovecot -a output, should it be needed. - - - - - root@mailaluno:~# dovecot -a # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian

Hi, has anyone figured out how to use the dovecot-antispam plugin with sa-learn? I need to pass the username (user(a)domain.tld) to sa-learn and --ham or --spam depending on the move. I was thinking of using the CRM14 option and replace the command and arguments but cannot find anything about the ability to pass the username. Any pointers would be welcome. N.

[Dovecot] May Dovecot help in users education
by Alexandre Chapellon 18 Aug '11

18 Aug '11

Hello, I was wondering if dovecot could help me in my project to smoothly make all my users switch to TLS encrypted POP / IMAP sessions and forget about cleartext. My first idea was to setup dovecot as a POP/IMAP proxy for my mailhosts and ask dovecot to display a warning message or slowdown non TLS sessions. Is there any way to achieve this with dovecot? Does anybody have another idea smoothly force used to switch to TLS? Regards. -- <http://www.horoa.net>

Hi, What I have been trying to achieve is to be able to authenticate users through openLDAP while using Postfix, Dovecot as IMAP server and squirrelmail. I keep getting the following error messages when trying to login to squirrelmail 2011-08-17 12:27:59 auth(default): Info: client in: AUTH 1 PLAIN service=imap secured lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=57794 resp=AGFkbWluAGFwbXg2c3Bu 2011-08-17 12:27:59 auth(default): Info: ldap(myuser,127.0.0.1): invalid credentials (given password: xxx) 2011-08-17 12:28:00 auth(default): Info: new auth connection: pid=1921 2011-08-17 12:28:01 auth(default): Info: client out: FAIL 1 user=myuser 2011-08-17 12:28:06 imap-login: Info: Aborted login (auth failed, 1 attempts): user=<myuser>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured This seems to be trivial but I just could not figure out what else went wrong.

[Dovecot] Slackware Dovecot recompile with SSL/TLS question
by CopalFreak 16 Aug '11

16 Aug '11

I am having some problems and was told to ask in this list to try and get some help. When asking elsewhere, I was told that I was too verbose, so I'll try to be as brief as possible, while still including all the pertinent info. Slackware 13.1.0 Dovecot 2.0.8 Postfix 2.4.3 MySQL (virtual users) Spamassassin 3.3.1 ClamAV 0.97.1 (without Amavis) Have wild-card SSL certs and CA from GoDaddy ##"postconf -a" >> cyrus >> dovecot I compiled Dovecot without SASL support and need to re-compile it WITH SASL support, but I don't want to mess up my existing configuration. (I have it the way I want it as far as where it's installed, where the conf files are located, UID, GID settings, etc.) Dovecot 2.0.13 is out and I would prefer to use the newer version assuming it doesn't have any problems that would prevent me from using it. Is there a way to re-compile (or upgrade) so that it doesn't change any of my existing settings? I would like to be able to bring it down, do upgrade, maybe copy some config files over the defaults etc, and bring it all back up within a few minutes instead of a week of tweaking and fixing stuff. Is there a way to do something like this : stop dovecot backup all dovecot conf files ./configure CPPFLAGS=-I/path/to/openssl LDFLAGS=-L/path/to/openssl --config_dir /etc/dovecot/dovecot.conf (or something like that..not sure what it actually is) make sudo make install edit conf files to point to SSL certs start dovecot IN CASE anything goes wrong, copy old config files back and restart dovecot to make it go back the way it was (only it's using the new 2.0.13 version) any suggestions and/or tips on how-to do this would be greatly appreciated. Thanks!

[Dovecot] mbox originally needed 0 bytes, now needs maxint bytes

I'm running dovecot 1.2.16 from the ports collection on FreeBSD 8.1-STABLE, amd64. I've long been getting the following in my logs, seemingly at random (so, only sometimes), when I access or move mail into mboxes: Aug 16 00:43:58 myhost dovecot: IMAP(mike): mbox /home/mike/mail/feedback: seq=88 uid=91 uid_broken=0 originally needed 0 bytes, now needs 18446744073709551615 bytes Whatever I'm trying to do always succeeds, but apparently dovecot is confused about something. That number (2^64-1) suggests it has to do with the amd64 architecture. Did a compile option get overlooked? Let me know if there's anything I need to do to get rid of these warnings. Thanks, Mike

Hi, I have been trying to set up Apache2, Postfix, Dovecot, openLDAP and squirrelmail on my Ubuntu Server 10.04 machine. The idea is to make use of the LDAP to authenticate users to login to squirrelmail to send/receive emails. I have been using the link - https://help.ubuntu.com/community/Postfix/DovecotLDAP, as a guide to get it all set up. I have checked the status for postfix and dovecot, and they both are up and running by using telnet. I have even installed openldapadmin to check and see if I've got the ldap working. I could login to openldapadmin and saw myself there with uid=msmith. I have also installed squirrelmail as my webmail. After all that installed, I went to localhost/squirrelmail on the firefox browser. It would not log me in. Later I found in the /var/log/dovecot-deliver.log file, I saw the following messages dovecot: Info: Dovecot v1.2.9 starting up (core dumps disabled) imap-login: Info: Aborted login (auth failed, 1 attempts): user=<msmith>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured imap-login: Info: Aborted login (auth failed, 1 attempts): user=<msmith(a)mycompany.com.au>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured imap-login: Info: Aborted login (auth failed, 1 attempts): user=<mike.smith(a)mycompany.com.au>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured I tried to login with three different usernames but none worked as shown above in the log file. I wonder if it is to do with method=PLAIN and secured. Any help would be greatly appreciated. Thank you

[Dovecot] Last login script
by Munroe Sollog 15 Aug '11

15 Aug '11

I am trying to implement a last login script, however I seem to be having lots of issues. We started with sqlite but we were having locking issues, so we moved to postgresql which seems to have alleviated database specific issues, but now people are complaining about randomly not being able to log in. I don't see any real errors in the logs (dovecot or postgresql) to explain their complaints though, all I am really getting is "Connection closed" here is the log line of a failed attempt (with debug output): http://pastebin.com/5RFgVa8V and here is what we are running as the 'mail executable': http://pastebin.com/L0ibyqSQ Any help would be greatly appreciated, thanks.

[Dovecot] LMTP over STDIN/STDOUT (non root user)
by Andrzej Adam Filip 15 Aug '11

15 Aug '11

Is it possible to get LMTP session over STDIN/STDOUT (for non root user)? I have configured dovecot to allow "server less" access to my mailbox using IMAP over STDIN/STDOUT. I would like to complete the setup by making fetchmail deliver fetched messages via LMTP over STDIN/STDOUT. -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu There is only one way to kill capitalism -- by taxes, taxes, and more taxes. -- Karl Marx

[Dovecot] [PATCH] net_connect_*(): Wait for fd to complete connect(2) when fd is non-blocking
by SATOH Fumiyasu 15 Aug '11

15 Aug '11

Hi, Dovecot ignores EINPROGRESS on connect(2) for non-blocking fd. This is wrong. After that, read(2) to fd (or write(2) to fd) fails with ENOTCONN if the connection of fd is not completed. The attached patch fixes this problem. -- -- Name: SATOH Fumiyasu (fumiyas @ osstech co jp) -- Business Home: http://www.OSSTech.co.jp/ -- Personal Home: http://www.SFO.jp/blog/

[Dovecot] Blocking auth services
by Peter Mogensen 15 Aug '11

15 Aug '11

Hi, I'm writing an passdb/userdb plugin to authenticate against an external daemon listening on a UNIX socket. The connection to the daemon is 1 request at a time and thus blocking (unlike passdb-ldap), but the daemon is preforking, so it can handle more connections at a time. I read from the Wiki: http://wiki2.dovecot.org/Design/AuthProcess * "The authentication may begin new authentication requests even before the existing ones are finished. ", and * "If the passdb uses connections to external services, it's preferred that they use non-blocking connections. Dovecot does this whenever possible (PostgreSQL and LDAP for example). If it's not possible, set blocking = TRUE. " ... which tells me to set the module as blocking and let more auth worker processes do the work - creating 1 daemon process for each auth worker process, I guess. But I also have the option, to let the passdb/userdb plugin maintain a pools of used/idle connections to the daemon and just pick a idle connection and moving it to the used pool on each auth_request. Which would save me the auth worker processes. Is there a preferred dovecot way? /Peter

[Dovecot] Parallel auth
by Bernhard Schmidt 15 Aug '11

15 Aug '11

Hello, we run a Dovecot 2.0.13 instance purely as SASL backend for Postfix, authenticating against a local passwd-file and our central LDAP database. # dovecot -n # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32.36-0.5-default x86_64 SUSE Linux Enterprise Server 11 # (x86_64) auth_mechanisms = plain login auth_verbose = yes passdb { args = /etc/dovecot/dovecot-passwd driver = passwd-file } passdb { args = /etc/dovecot/dovecot-ldap-simauth.conf.ext driver = ldap } protocols = none service auth { unix_listener /var/spool/postfix-postout/private/auth { group = postfix mode = 0660 user = postfix } } ssl = no There is only a single user in the passwd-file for monitoring. We monitor authentication delays for both this local user and one user from LDAP. Due to a firmware bug, our six-figures NAS causes extremely high LDAP delays (in the range of 20-60 seconds, instead of the usual 50ms) once an hour. The weird thing is, I also see these delays in the graph for the local user. Which got me thinking * are authentication requests handled serially by dovecot/auth? * any way to solve this situation for the local user (not to be blocked by the delayed LDAP query)? * any way to solve this situation for LDAP users? We could possibly do some loadbalancing if the auth-daemon opened several LDAP connections Thanks, Bernhard

[Dovecot] $IP not getting set?

Using dovecot 2.0.13. I went to implement relay-ctrl per directions on the Wiki, and failed. After running it down, as best as I can determine, the problem is that the $IP variable is not getting set (and thus not re-set in the script wrapper). I plunked a "set >> debug" into the script, and the only env var's that are set are as listed below (slightly sanitized for public display). Anyone have any ideas? I have tried both the Wiki-way, and this way: http://dovecot.org/list/dovecot/2009-December/045139.html with identical results.

[Dovecot] SQL passdb lookups not working
by Benjamin Montgomery 14 Aug '11

14 Aug '11

Hello everyone, I'm trying to make dovecot do user authentication against a SQL database. The passwords (managed by Django) are stored as salted SHA1 encoded in hex. I monkey patched Django's password method so that the password hash is made with <password><salt> (Django does <salt><password>, the patched method was verified to return same value as dovecotpw) and the passwords are stored in the database separately as the salted hash and the salt. When I query the values out of the database, I'm using MySQL's concat function to return the password as {SSHA.hex}<sha1 hash><salt>. Dovecot is not able to verify any passwords right now. I've scoured the wiki and I think my setup is correct...config info is below. Any advice on where to look for debugging or setup of my passwords would be appreciated! Ben dovecot-sql.conf: default_pass_scheme = SSHA.hex password_query = \ SELECT emailmanager_emailaddresses.account AS username, \ emailmanager_domain.name AS domain, \ CONCAT('{SSHA.hex}', \ emailmanager_userprofile.shadigest, \ emailmanager_userprofile.salt \ ) AS password \ FROM emailmanager_emailaddresses \ JOIN emailmanager_domain ON emailmanager_emailaddresses.id = emailmanager_domain.id \ JOIN emailmanager_userprofile ON emailmanager_emailaddresses.id = emailmanager_userprofile.id \ WHERE emailmanager_emailaddresses.account = '%n' \ AND emailmanager_domain.name = '%d'

[Dovecot] Clients can't retrieve new emails
by Jeff Van Epps 12 Aug '11

12 Aug '11

In a formerly working environment suddenly clients aren't notified of new emails and can't retrieve new emails. Server is Ubuntu 11.04 dovecot 1.2.15. Clients which fail are a Pre2 webOS 2.1 and TouchPad webOS 3.0 (those are OS versions, I don't know which particular flavor/version the IMAP clients are); there is also a Thunderbird 3.1.11 client on the same system as the server which works properly. The clients never report an error. I got as far as configuring rawlog: in: ~A2 NAMESPACE ~A3 SELECT "INBOX" ~A4 LIST "" * ~A5 UID STORE 0 +FLAGS.SILENT (\Seen) ~A6 UID STORE 0 +FLAGS.SILENT (\Seen) out: * OK [RAWLOG TIMESTAMP] 2011-08-01 08:28:33 ~A1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS] Logged in * NAMESPACE (("" "/")) NIL NIL ~A2 OK Namespace completed. * FLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk Junk) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk Junk \*)] Flags permitted. * 101 EXISTS * 0 RECENT * OK [UNSEEN 63] First unseen. * OK [UIDVALIDITY 1222650706] UIDs valid * OK [UIDNEXT 863] Predicted next UID * OK [HIGHESTMODSEQ 1903] Highest ~A3 OK [READ-WRITE] Select completed. * LIST (\NoInferiors \UnMarked) "/" "Trash" * LIST (\NoInferiors \UnMarked) "/" "Sent" * LIST (\NoInferiors \UnMarked) "/" "INBOX" ~A4 OK List completed. ~A5 BAD Error in IMAP command UID STORE: Invalid uidset ~A6 BAD Error in IMAP command UID STORE: Invalid uidset I've searched and read messages saying that there is no such thing as UID 0.

[Dovecot] Unknown setting: service
by Patrick Westenberg 11 Aug '11

11 Aug '11

Hi guys, I setup a new box with Debian Squeeze 64bit and installed dovecot from the sources. However, I can't start dovecot or even use doveconf: root@imap01:~# doveconf -n # 2.0.13: /usr/local/etc/dovecot/dovecot.conf doveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/conf.d/10-mail.conf line 111: Unknown setting: mail_uid Why is mail_uid and mail_gid an unknown setting? On my other box the configuration is identical (but Dovecot is upgraded from early 2.0.x versions to the current one) If I comment the mail_uid and mail_gid lines, I get another error: root@imap01:~# doveconf -n doveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/conf.d/10-master.conf line 17: Unknown setting: service doveconf: Error: managesieve-login: dump-capability process returned 89 doveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/conf.d/10-master.conf line 17: Unknown setting: service Everything I could find on Google are problems after upgrading from 1.x to 2.x What went wrong?

Hey Guys, Have any of you seen an issue with Thunderbird in which the computer has to be rebooted for email to be downloaded? I have been looking over the InterWebs and I cannot find anything. I can see new email on the server as well. Where would be a good place to start for troubleshooting this issue? Thanks

Is there a way to match the destination mailbox in a sieve script? The email comes in by dovecot-lda -d $user -m Sent Now the sieve script should somehow match the mailbox "Sent".

[Dovecot] Dovecot quota dict
by Juan Bernhard 10 Aug '11

10 Aug '11

Hi, Im using dovecot with maildir++ quota and I have this problem, maybe some of you already solve this and can helpme. I want to use some flat file to tell exim and dovecot the quota limit for each user, i tried to work with exim and maildirsize file, but exim just ignores the limits there. I need a way (a really simple one, i dont want to create a database or an ldap server just for this) to tell exim and dovecot to lookup some file to get the quota limits. I know how to doit with exim, now i need to know how to tell dovecot to read the quota limits from this file. I know that dovecot can read the quota limit from the userdb, but im using pam and i dont want to change the entire auth schema. Can I configure dovecot to get the quota limit from a file using pam as userdb?

Cause 8 The BlackBerry Internet Service downloads any email message with an email message UID that it did not find during the previous connection. If the email message UIDs are changed by the messaging server, duplicate email messages are received. This behavior also applies to any email message that has a blank UID. Resolution 8 To resolve this issue, complete one of the following procedures. Make sure that the message UIDs of email messages on the integrated account messaging server do not change or that email messages are not added back to the inbox of the associated account. Ask your administrator if the message UIDs are changing. In the case of an email message that has a blank UID, have your administrator remove the email message from the email server to prevent it from being delivered repeatedly. Delete email messages from the BlackBerry smartphone using the Mailbox & Handheld setting (email messages will be deleted from the associated email account messaging server and will not be retrieved again by the BlackBerry Internet Service).

[Dovecot] authentication via LDAP
by Gerardo Herzig 09 Aug '11

09 Aug '11

Hi all. I have a couple of questions. ANY of those will solve mi situation. 1) 'Complex' LDAP validation: I need to validate a user in the 2 step authentication / authorizacion mech. The 'users' (with the password) are in ou=Person,o=Work the group which contains the mail users is in cn=MailUsers,ou=Groups,o=Work Can dovecot make such a thing? Cause im not shure if i can make this in a single ldap filter. 2) If not... 2.1) Does dovecot accept more than 1 rule for authenticating? 2.2) Does dovecot accept an arbitrary program for authentication? Well, that's all for now. Thanks! Gerardo

[Dovecot] mail delivery location wrong
by Firma Averlon 09 Aug '11

09 Aug '11

Hi, thanks for offering the oportunity to place a question here. I am now already working since a week to get postfix and dovecot working on a ubuntu 11.04 server. Hard task. First step was naturally to get familiar with the idea behind the archtitecture. I have come very far, but the "last dirty mile" is probably the hardest. My architecture: Postfix Dovecot OpenLDAP Thunderbird as client with pop3 I can meanwhile send e-mails and open my mailbox in thunderbird (not receiving mails so far). The reason why not receiving e-Mails is simply: When sending the mails they are stored in a different directory as where dovecot will look for them !!!! Error message from log: Aug 8 14:09:01 server dovecot: deliver(vmail): maildir: data=/home/vmail//vmail/Maildir Aug 8 14:09:01 server dovecot: deliver(vmail): maildir: data=/home/vmail//vmail/Maildir Aug 8 14:09:01 server dovecot: deliver(vmail): maildir++: root=/home/vmail//vmail/Maildir, index=, control=, inbox=/home/vmail//vmail/Maildir Aug 8 14:09:01 server dovecot: deliver(vmail): maildir++: root=/home/vmail//vmail/Maildir, index=, control=, inbox=/home/vmail//vmail/Maildir What you immediatly see: "vmail//vmail" Although, when authenticating, the result is: Aug 8 14:06:30 server dovecot: auth(default): master out: USER#0113#011userxxx@av.loc#011gid=5000#011home=/home/userxxx#011uid=5000#011mail=/home/vmail/av.loc/userxxx/Maildir/ The following settings are in place: main.cf of postfix: virtual_mailbox_domains = /etc/postfix/vhosts virtual_mailbox_base = /home/vmail virtual_mailbox_maps = ldap:/etc/postfix/ldap-virtual.cf virtual_minimum_uid = 1000 virtual_uid_maps = static:5000 virtual_gid_maps = static:5000 virtual_transport = dovecot mailbox_command = /usr/lib/dovecot/deliver beside others. master.cf of postfix dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -a ${recipient} dovecot.conf sendmail_path = /usr/sbin/sendmail mail_location = maildir:/home/vmail/%d/%n/Maildir beside others. I guess, these are the ones influencing where to store the mail and pick it up. A list of the related filesystem: /home/vmail/ drwx-w--w- 4 vmail vmail 4096 2011-08-08 08:56 av.loc/ drwx------ 3 vmail vmail 4096 2011-08-08 09:42 vmail/ Wher you can see, the structure according "mail_location" parameter of dovecot.conf does show effect, but the mails are stored in /home/vmail//vmail.....". The whole bunch of documentation I have read meanwhile makes my head circle around. You could hopefully give me some help. -- Mit freundlichen Grüßen / Kind Regards Hr. Karl-Heinz Fischbach

[Dovecot] How to make dovecot-lda/deliver mark a message as seen
by Stefan Piegsa 08 Aug '11

08 Aug '11

Hello everybody, I am using dovecot 2.0.13 and have a special case here in which I want a mail that is delivered locally with dovecot-lda to be marked as "seen". In dovecot 1.1.7 I succeeded to achive this, by modifing deliver.c so that upon adding a -S switch to the command arguments, the flag MAIL_SEEN was added to the call of mailbox_copy(). This seemed to work pretty good. With the new version, i tried to do something similar by selectively adding mail_update_flags(ctx.src_mail, MODIFY_ADD, MAIL_SEEN); just before the call of mail_deliver(), whenever the -S argument is given. But this does not work. What is wrong? Is there a better way to set MAIL_SEEN for a locally delivered mail? I would prefer a method that does not require to mess around in the dovecot sources. :-) Thanks in advance & Best Regards, Stefan

[Dovecot] Dovecot + LDAP login issues
by ml lists 07 Aug '11

Morning all, I've managed to work my self into a corner and hoping someone can help me out I have OpenLDAP and Dovecot installed based on the following documents: https://help.ubuntu.com/community/DovecotLDAP https://help.ubuntu.com/community/OpenLDAPServer When Dovecot is set up to log in without using LDAP, connections work fine. However as soon as I change the dovecot.conf to use ldap I get the following error when trying to log in: error in syslog: dovecot: auth(default): ldap(myuser,10.10.10.10): invalid credentials (given password: myuserpasswd) dovecot: auth(default): client out: FAIL#0112#011user=myuser I have checked via phpLDAPadmin that the password I am entering matches what is in the database, so from what I can see the issue lies in how Dovecot is passing the password to openLDAP, though I may be way off base here. No special characters in the passphrase other than spaces. Would anyone be able to shed some light on this?

[Dovecot] Dovecot 2.x configuration
by Vincent Richomme 07 Aug '11

07 Aug '11

Hi, sorry to post about that but I have some issues to migrate my dovecot 1.x to 2.x. I have installed dovecot 2.x package on ubuntu natty(package were generated from sources found in debian testing), and I have modified config files like that : dovecot.conf: ------------- !include_try /usr/share/dovecot/protocols.d/*.protocol listen = *, :: !include conf.d/*.conf !include_try local.conf conf.d/10-auth.conf: --------------------- !include auth-sql.conf.ext so I have uncommented the auth-sql.conf.ext because I want a sql auth but these file is not available so I copied the file ../dovecot-sql.conf.ext and rename it into auth-sql.conf.ext. conf.d/auth-sql.conf.ext: --------------------- driver = mysql connect = host=127.0.0.1 dbname=foobarserver user=foo password=bar default_pass_scheme = PLAIN-MD5 password_query = SELECT email as user, password FROM view_users WHERE email='%u'; When I try to load the config I get the following error : root@sd-30635:/etc/dovecot/conf.d# dovecot -n # 2.0.13 (ba03935cc599): /etc/dovecot/dovecot.conf doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/auth-sql.conf.ext line 29: Unknown setting: driver doveconf: Error: managesieve-login: dump-capability process returned 89 doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/auth-sql.conf.ext line 29: Unknown setting: driver I searched on the mailing list and I found an answer but I am still not sure how to solve it. UPDATE : after trying to use my brain I found the solution to my issue but I am still posting to help people that may have the same problem and to make you notice that the current configuration files are not logical. I mean in conf.d/10-auth.conf you can uncomment auth-sql.conf.ext but the file is not available (maybe it's a packaging problem). So I did the following steps : cp conf.d/auth-system.conf.ext conf.d/auth-sql.conf.ext Then I have edited conf.d/auth-sql.conf.ext: passdb { driver = mysql args = /etc/dovecot/dovecot-sql.conf.ext } OK so far so good, next problem is about the old configuration lines : # It's possible to export the authentication interface to other programs: socket listen { master { # Master socket provides access to userdb information. It's typically # used to give Dovecot's local delivery agent access to userdb so it # can find mailbox locations. path = /var/run/dovecot/auth-master mode = 0600 # Default user/group is the one who started dovecot-auth (root) user = vmail #group = } client { # The client socket is generally safe to export to everyone. Typical use # is to export it to your SMTP server so it can do SMTP AUTH lookups # using it. path = /var/run/dovecot/auth-client mode = 0660 } } Where should I put them in the new config file hierarchy ? And do I still need them ? Just for information I have based my mail setup on the following guide : http://workaround.org/ispmail/etch Thanks

[Dovecot] DoveCot LDA prefetch fails with LDA, works with POP client
by Zhou, Yan 05 Aug '11

05 Aug '11

Hi there, I am using DoveCot 1.0.7. I know it is real old, but we have to work with it. I have configured LDAP lookup with password prefetch in DoveCot. I can successfully receive emails through DoveCot, thus proving my password prefetch and user authentication are good. The problem is when I use Postfix to deliver message to DoveCot via LDA. My postfix master.cf looks like this: dovecot unix - n n - - pipe flags=Rhu user=hubdirect null_sender= argv=/usr/libexec/dovecot/deliver -e -f ${sender} -d ${user} Given a message, Postfix looks up LDAP and find the user associated with the recipient address and delivers the message using LDA. LDAP logs indicates that Postfix is returning the right user. The problem is that DoveCot complains "passdb did not return userdb entries", but I do not know which entries passdb failed to return. Here is what I have in dovecot-ldap.conf. I have tried different things in "user_attrs", DoveCot keeps complaining the same thing. user_attrs = username=user user_filter = (&(objectClass=DirectUser)(username=%u)(roles=*ROLE_EDGE_EMAIL*)) pass_attrs = username=user,password=password,username=userdb_user,usermaildirectory=u serdb_mail,userhomedirectory=userdb_home,825=userdb_uid,825=userdb_gid pass_filter = (&(objectClass=DirectUser)(username=%u)(roles=*ROLE_EDGE_EMAIL*)) The documentation says LDA does not use prefetch, but the log seems to indicate otherwise. I clearly see the "service=deliver" is authenticating the user first, thus using password prefetch. Can someone clarify this?

[Dovecot] director monitoring?
by Kelsey Cummings 05 Aug '11

05 Aug '11

I'm working the kinks of a new director based setup for the eventual migration away from courier. At this point, with everything basically working I'm trying to ensure that things are properly monitored and I've run into an issue. There doesn't appear to be a way to get dovecot to tell if it is (or is not) connected and properly synced with the other director servers in the ring apart from the logs. It seems like this is an important piece of information -- without it, it isn't apparent how you would be able to tell if your director servers have lost track of each other. I'm also curious what people are doing to health check their director servers when they are running load balancing upstream of them as well. It doesn't seem like it is a good idea to let the load balancers check all the way through to the real servers since a failure on the target real server could end up leading to a director being dropped from the pool (if so, it is most likely that the other directors would be dropped as well.) Otherwise, the health check failure tolerance at the load balancer must be greater than the tolerance for failure of the real servers on the director- a dead director could end up in the pool for longer than desired, or anyway, long enough to be sure that it isn't a transient failure on the real server behind it. A better method would seem to be for the load balancers to query the director for the number of active back-end servers and, so long as it was over a given threshold, to assume that the director is otherwise able to do its job and rely on external monitoring to pickup internal failures where dovecot isn't able to successfully proxy the connection to one of the real servers. So, how are people doing this in the real world? -- Kelsey Cummings - kgc(a)corp.sonic.net sonic.net, inc. System Architect 2260 Apollo Way 707.522.1000 Santa Rosa, CA 95407

[Dovecot] Question about memory management in plugins
by Peter Mogensen 04 Aug '11

04 Aug '11

Hi, I've writing an passdb/userdb plugin (see my previous question about a plugin authenticating via a UNIX socket protocol). Now... the protocol spoken over this socket is JSON-based and I'm using a SAX-like event based parser which maintains a parse context between callbacks. Now... I'm a little bit in doubt about which dovecot memory management method would be best for data in this parser context. Alloc-only pools seems wrong cause the parser object is used as long as the connection is open and there might run many auth requests over the connection before it's freed making the pool grow for long time. Data stack allocation won't work either, since with all this async network and callbacks, there's really no where to place the stack frame. So I end up using i_* and i_free for all data during the lifetime of the connection. Is there a better way? If I could only free my pool-allocated data, but I can't since it's almost never the last allocated data I want to free. /Peter

[Dovecot] [BUG?] LDAP authentication with aliases issues
by Paweł Lęcznar 04 Aug '11

04 Aug '11

Hello, I am trying to configure Dovecot with LDAP authentication. My LDAP tree structure is as following: dc=root,dc=pl \_ ou=Users \_ uid=test \_ ou=Mail \_ ou=domain.pl \_ uid=alias_to_test I cannot authenticate using 'uid=alias_to_test,ou=domain.pl,ou=Mail,dc=root,dc=pl'. If I try to authenticate using 'uid=alias_to_test,ou=domain.pl,ou=Mail,dc=root,dc=pl', following entry appears in the Dovecot's log file: #v+ auth: Debug: client in: AUTH 1 PLAIN service=imap secured lip=127.0.0.1 rip=127.0.0.1 lport=993 rport=59818 resp=YWxpYXMxQGFsaWFzeS5wbABhbGlhczFAYWxpYXN5LnBsAGFzZHF3ZWFzZA== auth: Debug: ldap(alias_to_test(a)domain.pl,127.0.0.1): pass search: base=uid=alias_to_test,ou=domain.pl,ou=Mail,dc=root,dc=pl scope=base filter=(&(objectClass=posixAccount)) fields=uid,userPassword auth: Debug: auth(alias_to_test(a)domain.pl,127.0.0.1): username changed alias_to_test(a)domain.pl -> test auth: Debug: ldap(test,127.0.0.1): result: uid(user)=test userPassword(password)={CRYPT}ACnZvF4.K46UI auth: Debug: client out: OK 1 user=test auth: Debug: ldap(test,127.0.0.1): user search: base=uid=test,ou=,ou=Mail,dc=root,dc=pl scope=base filter=(&(objectClass=posixAccount)(uid=test)) fields=homeDirectory,uidNumber,gidNumber auth: Debug: master out: FAIL 2551840769 #v- In the LDAP server log file, following entries appear during authentication attempt #v+ ldap slapd[11729]: conn=1125 op=0 BIND dn="cn=Manager,dc=root,dc=pl" method=128 ldap slapd[11729]: conn=1125 op=0 BIND dn="cn=Manager,dc=root,dc=pl" mech=SIMPLE ssf=0 ldap slapd[11729]: conn=1125 op=0 RESULT tag=97 err=0 text= ldap slapd[11729]: conn=1125 op=1 SRCH base="uid=alias_to_test,ou=domain.pl,ou=Mail,dc=root,dc=pl" scope=0 deref=3 filter="(&(objectClass=posixAccount))" ldap slapd[11729]: conn=1125 op=1 SRCH attr=uid userPassword ldap slapd[11729]: conn=1125 op=1 SEARCH RESULT tag=101 err=0 nentries=1 text= ldap slapd[11729]: conn=1125 op=2 do_search: invalid dn: "uid=test,ou=,ou=Mail,dc=root,dc=pl" ldap slapd[11729]: conn=1125 op=2 SEARCH RESULT tag=101 err=34 nentries=0 text=invalid DN #v- It seems that LDAP AuthDatabase doesn't change the context when looking up for the target object, to which the alias points. Futhermore, the filter for the target object '(&(objectClass=posixAccount)(uid=test))' was not defined by me anywhere in the configuration file 'dovecot-ldap.ext'. I have tried both authentication ways: 'password lookups' and 'authentication binding' with the same result. However, There is no problem to authenticate as 'uid=test,ou=Users,dc=root,dc=pl' (of cource after modifying the configuration file listed at the end). I suppose that it can be a bug in LDAP AuthDatabase, so I am writing this post as a potential bug report.

[Dovecot] questions about ldap auth
by Gerardo Herzig 04 Aug '11

04 Aug '11

Hi all. I have a couple of questions. ANY of those will solve mi situation. 1) 'Complex' LDAP validation: I need to validate a user in the 2 step authentication / authorizacion mech. The 'users' (with the password) are in ou=Person,o=Work the group which contains the mail users is in cn=MailUsers,ou=Groups,o=Work Can dovecot make such a thing? Cause im not shure if i can make this in a single ldap filter. 2) If not... 2.1) Does dovecot accept more than 1 ldap filter for authenticating? 2.2) Does dovecot accept an arbitrary program for authentication? Well, that's all for now. Thanks! Gerardo

[Dovecot] Local delivery via deliver fails for 1 user in alias
by Greg Woods 04 Aug '11

04 Aug '11

Hi all, I'm a bit baffled. I have an OS X server 10.6.8 and everything was working fine. Now however I seem to be having some issues and I'm unable to find log entries to help point me to the error. I have an alias, sales at cirrusav.com, which forwards mail to myself and two others. This works fine most of the time, but on occasion messages are not delivered to one user. It is possible that one of the other users fails delivery occasionally as well, though this has not been rigorously tested. I always seem to get the messages. I have logging set to debug via the OS X server admin. Looking through /var/log/mailaccess.log I see all the same entries for each user even when messages fail to deliver. The only difference I notice is the order. I see some messages about corrupt index cache files. I can find the missing message in failing user's dovecot.index.cache. However I can not find the message in the cur sub directory or anywhere else (grep -i regency ...). I can find the file in my dovecot.index.cache and cur directory. Details below. I'm continuing to research the internet, but don't know what I'm looking for. I'm also concerned that we might be dropping more mail. Thoughts anyone? Thank you in advance for your help.

[Dovecot] Pigeon Sieve, redirect action and SPF
by Pedro Ribeiro 03 Aug '11

03 Aug '11

Since I've upgraded to dovecot 2.0.13 + Pigeonhole 0.2.3 (Gentoo package) I've received a few complains of users about rejected messages. Investigating the problem, I've seen that when the external sender server publishes SPF information, when some message is sent from there to one of my users that has a Sieve redirect action active to another external system (that does SPF validation), the message is rejected because our system only changes the envelope "rcpt to" in the redirection and the "mail from" remains the original. When the end server does the SPF validation it fails because my server isn't in the IP allow list for the domain of the original sender. I never seen this problem in the old Dovecot+CMUSieve. Shouldn't the sender be changed in the envelope "mail from" from the original one to the recipient that made the Sieve redirection? Keep the excellent work with dovecot and related projects! TIA! -- Best regards, =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Pedro Ribeiro IPLNet - Rede de dados e comunicações Instituto Politécnico de Lisboa (IPL) Mail: mailto:pribeiro AT net.ipl.pt VoIP: sip:pribeiro AT net.ipl.pt =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

Hi all, I'm testing Dovecot version 1.2.17 on FreeBSD 8.2-RELEASE using ZFS as filesystem. Searching on google I've ridden about some problem concerning indexes and mmap. I wold like to know if this problem persists on the latest releases. Thanks in advance. Roberto Giuliani.

[Dovecot] sievec - manual compile of global sieve scripts?
by Thomas Harold 02 Aug '11

02 Aug '11

How do you compile global scripts using the sievec command without making the script directory owned (and group writable) by the vmail user? http://wiki2.dovecot.org/Pigeonhole/Sieve/Usage # cd /etc/dovecot/sieve/before/ # (edit some script like spam.sieve that runs for everyone) # /usr/local/bin/sievec spam.sieve spam.svbin sievec(root): Error: sieve: binary save: failed to create temporary file: open(spam.svbin.hostname.26921.) in directory /etc/dovecot/sieve/before failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /etc/dovecot/sieve/before, euid is not dir owner) # ls -la /etc/dovecot/sieve/before/ drwxrwxr-x 2 root root 4096 Aug 1 15:56 . drwxr-xr-x 5 root root 4096 Aug 1 13:23 .. -rw-rw-r-- 1 root root 477 Aug 1 15:33 spam.sieve Or do I just make the /etc/dovecot/sieve/ tree owned and writable by the vmail:vmail user?

[Dovecot] web interface for user creation/vacation
by Chris Cappuccio 02 Aug '11

02 Aug '11

What are the best web interfaces for user/domain management, perhaps one that also allows individual users to edit vacation msgs? Right now I'm using a postfixadmin based mysql control panel. Curious what is the better stuff out there that people are using with dovecot/sieve these days? Are there any decent front-ends to setup/manage per-user sieve filters?

[Dovecot] Redelivery of messages in Maildir through sieve to be re-sorted
by Thomas Harold 01 Aug '11

01 Aug '11

http://wiki2.dovecot.org/HowTo/RefilterMail That solution looks great for a single user, but is it possible to do a larger version that runs for everyone on the server? I'm speaking specifically of a virtual setup where all mailboxes are owned by a common UID/GID. It seems like (with brief testing) that I could search for mail inside of a "Refilter" folder, like /var/vmail/domain.ext/username/Maildir/.Refilter/{cur|new}, and shove that through dovecot-lda. I would just need to put the username/domain.ext back together in the format of username(a)domain.ext. /usr/libexec/dovecot/dovecot-lda -e -d username(a)domain.ext -p (path to message) If dovecot-lda doesn't throw an error, then I could delete the message from the "Refilter" folder and move onto the next message. Or does Dovecot get horribly confused when messages vanish out of the "cur" folder?

[Dovecot] Dovecot and pigeonhole: mail not filtered
by Sebastian Schlingmann 01 Aug '11

01 Aug '11

Hi everyone, I am running dovecot for quite some time now (currently version 2.0.13). Recently I tried to get Sieve and Managesieve to run. For this purpose I installed pigeonhole 0.2.3 and added sieve to the mail_plugins for lmtp and to the protocols. I also copied the sample 90-sieve.conf and 20-managesieve.conf into my /etc/dovecot/conf.d/ directory. In 90-sieve.conf I uncommented the sieve and sieve_dir options and set them to my desired values. After a restart of dovecot I was able to use my webmailer to add sieve scripts via the managesieve protocol. However the sieve scripts do not trigger. Is there any way to test if sieve is even executed when a mail arrives? mail_debug did not give me any relevant information. BTW: I checked my sieve script with the sieve-test command and it would execute the right action (move a mail into a directory). Bye Sebastian

[Dovecot] Dovecot 2.0.x + Sendmail 8.14.4 SMTP AUTH not working
by Serhiy Kolesnyk 31 Jul '11

31 Jul '11

Hello! After moving from Centos 5.6 to Centos 6, I figured that Sendmail minor version was updated from 8.13.x to 8.14 and Dovecto from 1.2 to 2.0.x In previous configuration SMTP auth worked fine (no SASAUTHD neccessary) for virtual users table. Dovecot was authenticating virtual users virtual checking dovecot.passwd file. I'm not sure how Sendmail was processing SMTP AUTH for virtual users connecting via email clients since there was no obvious connection to Dovecot authentication. But SMTP AUTH was working and virtual users could send email via SSL. Now after this recent upgrade I looked into Dovecot conf changes and updated it according. POP/IMAP are working and Sendmail does deliver incoming mail to the mbox folders. What stopped working is SMTP AUTH. Here's maillog excerpt of authentication process: Jul 29 23:46:11 one2action sendmail[2865]: AUTH: available mech=CRAM-MD5 DIGEST-MD5 LOGIN GSSAPI PLAIN, allowed mech=LOGIN PLAIN Jul 29 23:46:11 one2action sendmail[2865]: STARTTLS=server, get_verify: 0 get_peer: 0x0 Jul 29 23:46:11 one2action sendmail[2865]: STARTTLS=server, relay=136-31-132-95.pool.ukrtel.net [95.132.31.136], version=TLSv1/SSLv3, verify=NO, cipher=RC4-MD5, bits=128/128 Jul 29 23:46:11 one2action sendmail[2865]: STARTTLS=server, cert-subject=, cert-issuer=, verifymsg=ok Jul 29 23:46:11 one2action sendmail[2865]: AUTH: available mech=CRAM-MD5 DIGEST-MD5 LOGIN GSSAPI PLAIN, allowed mech=LOGIN PLAIN Jul 29 23:46:11 one2action sendmail[2865]: p6TMkB95002865: --- 220 one2action.com ESMTP Sendmail 8.14.4/8.14.4; Fri, 29 Jul 2011 23:46:11 +0100 Jul 29 23:46:11 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: <-- EHLO astronaut Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-one2action.com Hello 136-31-132-95.pool.ukrtel.net [95.132.31.136], pleased to meet you Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-ENHANCEDSTATUSCODES Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-PIPELINING Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-8BITMIME Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-SIZE Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-DSN Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-ETRN Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-AUTH LOGIN PLAIN Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250-DELIVERBY Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 250 HELP Jul 29 23:46:12 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: <-- AUTH LOGIN Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 334 VXNlcm5hbWU6 Jul 29 23:46:12 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 334 UGFzc3dvcmQ6 Jul 29 23:46:12 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 535 5.7.0 authentication failed Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: AUTH failure (LOGIN): generic failure (-1) SASL(-1): generic failure: checkpass failed, relay=136-31-132-95.pool.ukrtel.net [95.132.31.136] Jul 29 23:46:12 one2action sendmail[2865]: STARTTLS=read, info: fds=8/4, err=2 Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: --- 421 4.4.1 one2action.com Lost input channel from 136-31-132-95.pool.ukrtel.net [95.132.31.136] Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: lost input channel from 136-31-132-95.pool.ukrtel.net [95.132.31.136] to TLSMTA after auth Jul 29 23:46:12 one2action sendmail[2865]: p6TMkB95002865: 136-31-132-95.pool.ukrtel.net [95.132.31.136] did not issue MAIL/EXPN/VRFY/ETRN during connection to TLSMTA Here's dovecot -n # dovecot -n # 2.0.beta6 (3156315704ef): /etc/dovecot/dovecot.conf # OS: Linux 2.6.39.1-linode34 i686 CentOS Linux release 6.0 (Final) auth_cache_negative_ttl = 3600 s auth_debug_passwords = yes auth_mechanisms = plain login DIGEST-MD5 cram-md5 auth_worker_max_count = 3 default_client_limit = 10 default_process_limit = 5 disable_plaintext_auth = no listen = * log_path = /var/log/dovecot.log mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail mbox_write_locks = fcntl passdb { args = scheme=MD5-CRYPT username_format=%u /etc/dovecot/dovecot.passwd driver = passwd-file } passdb { args = dovecot driver = pam } passdb { args = /etc/passwd driver = passwd-file } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = smmsp mode = 0666 user = smmsp } unix_listener dovecot-auth { group = smmsp mode = 0666 user = smmsp } } service imap-login { inet_listener imaps { port = 993 ssl = yes } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_cert = </etc/pki/tls/certs/sendmail.pem ssl_cipher_list = TLSv1+HIGH:!SSLv2:RC4+MEDIUM:!aNULL:!eNULL:!3DES:@STRENGTH ssl_key = </etc/pki/tls/certs/sendmail.pem userdb { args = username_format=%u /etc/dovecot/dovecot.passwd driver = passwd-file } protocol lda { auth_socket_path = /var/run/dovecot/auth-master postmaster_address = postmaster(a)example.com } protocol imap { imap_client_workarounds = delay-newmail } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } As I understand Sendmail now can't find Dovecot authentication via userdb and that's why a client isn't authenticated.

[Dovecot] lda_mailbox_autosubscribe - v2 wiki is a bit unclear
by Thomas Harold 29 Jul '11

29 Jul '11

In the old wiki: http://wiki1.dovecot.org/LDA -m <mailbox>: Destination mailbox (default is INBOX). If the mailbox doesn't exist, it's created (unless -n is used). If message couldn't be saved to the mailbox for any reason, it's delivered to INBOX instead. -s: Subscribe to mailboxes that are automatically created (via -m parameter or fileinto Sieve action). (v1.1.3+) Those have been replaced in Dovecot v2 with: # Should saving a mail to a nonexistent mailbox automatically create it? lda_mailbox_autocreate = no # Should automatically created mailboxes be also automatically subscribed? lda_mailbox_autosubscribe = no But neither of those options are mentioned on the LDA wiki page: http://wiki2.dovecot.org/LDA It's only mentioned in passing on the 2.0 page that explains the changes between 1.2 and 2.0.

We use qmail + vpopmail + dovecot, limits and alias are in vpopmail mysql database, it has worked ok. The .qmail-default: | /data/vpopmail/bin/vdelivermail '' bounce-no-mailbox | /var/qmail/bin/preline -f /usr/local/dovecot/libexec/dovecot/deliver -d $EXT@$USER When you send a message to alias works OK. The problem that is happening that is sent to asdf(a)domain.com asdf(a)domain.com he is doubling the email. Come the email that you sent / wrote an email and more with nearly no head, no matter. Searching is very realized that something related to Deliver the dovecot. Can you help us? Tips? Thank you all.

[Dovecot] want only usder in userfile/passfile and use to login user@domain
by Erik - versatel 28 Jul '11

After adding: auth_username_format=%Lu the %d domain is unfolleded correctly. (and not empty anymore) Maybe a good idee to make a remark in the text Virtual Users about that. I use: passdb: driver: passwd-file args: /etc/dovecot/vhosts/%d/etc/shadow userdb: driver: static args: uid=virtual gid=virtual home=/var/mail/vhosts/%d/%u In the password-file (shadow) i have to add users in the form user@domain. I want to add users in the form user I have also tryed not a static userdb but a real one; see example Dynamic-passwd locations. To get this working i had to add mail-uid and mail-gid. But still it has the same form user@domain and not user Can anybody tell my how to get ride of the domain part in the passwd en userfile. I still want the user to login with user@domain Thanks.

[Dovecot] National characters

Hi, I upgrade my server an I have dovecot 2.0.9 (on RedHat 6) and my user uses Thunderbird 5.0 (on Windows XP). I use authentication via LDAP (Windows server 2003 AD). When users use in password diacritic marks (ą,ć,ę,ł,ń,ó) authentication failed. For example when user test have password: Sierpieńłą*123 in log file item appears: localhost dovecot: auth: ldap(test,192.168.0.68): invalid credentials (given password : SierpieDB#005*123) What can I do? Thanks

[Dovecot] dovecot quota feature request
by Shing 28 Jul '11

28 Jul '11

Hi all, I'm going to implement before queue quota check with postfix to prevent bounce mail, the quota information is stored into mysql using dovecot quotadict, it would be nice that dovecot can have an option to switch the quota check with (used space < quota) instead of (used space+mail size < quota), so that i can write a simple sql statement to check_recipient_access to reject those mail, thanks. Shing

[Dovecot] Store quota on passwd-file?? Not work
by Sébastien FOURCADE 28 Jul '11

28 Jul '11

Hello all, I have installed Dovecot 1.2.15 and Postfix 2.7.1 on my Debian 6.This install no include MySQL, I prefer to store Password/User in a file... File /etc/dovecot/passwd contains :user2@domain.com:{CRAM-MD5}::::userdb_mail=maildir:~/Maildir userdb_quota_rule=*:bytes=300M File /etc/dovecot/users :user2@domain.com::3000:3000::/home/vmail/domain.com/user2/:/bin/false:: What is the correct syntax for my file to use a different per-user quota ? This example not work on my Dovecot :user2@domain.com:{CRAM-MD5}:3000:3000::/home/vmail/domain.com/user2::userdb_mail=maildir:~/Maildir userdb_quota_rule=*:storage=200Muser2@domain.com:{CRAM-MD5}:3000:3000::/home/vmail/domain.com/user2::userdb_quota_rule=*:bytes=200M Thx.

[Dovecot] set delay between pop3-logins
by tonjg 28 Jul '11

28 Jul '11

I'm using dovecot 1.1.8 on a raq4 server running centos 4.8 Is it possible to set a time delay between all dovecot pop3-logins? say 20 - 30 seconds for example? My reason is I want to thwart the constant login attempts from hackers hunting for an open relay. It's no good blocking the ip address because every hack attempt comes in from a different address. I'm the only user on the server so no-one else would be affected by such a delay. Thanks for any pointers -- View this message in context: http://old.nabble.com/set-delay-between-pop3-logins-tp32134037p32134037.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] lmtp multiple recipients fail
by flylordis flylordis 28 Jul '11

28 Jul '11

Hello, I am having a problem with the lmtp delivery of mail addressed to multiple recipients. The first recipient receives the mail correctly but the next recipients do not. ltmp apparently tries to create a link from the subsequent recipients' mail store to the first recipient mail store and fails. This returns 451 smtp codes to the sender which then resends at some later time. Please see below for users jerry, steve, and mary. The message to jerry gets written but not steve or mary: ul 27 11:24:41 testmailserver dovecot: lmtp(12412): Debug: none: root=, index=, control=, inbox= Jul 27 11:24:41 testmailserver dovecot: lmtp(12412): Connect from 143.112.53.4 Jul 27 11:24:41 testmailserver dovecot: lmtp(12412): Debug: auth input: jerry home=/spool/mail/j/jerry system_groups_user=jerry uid=18738 gid=4025 Jul 27 11:24:41 testmailserver dovecot: lmtp(12412): Debug: auth input: steve home=/spool/mail/s/steve system_groups_user=steve uid=9838 gid=3011 Jul 27 11:24:41 testmailserver dovecot: lmtp(12412): Debug: auth input: mary home=/spool/mail/m/mary system_groups_user=mary uid=7007 gid=3011 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Effective uid=18738, gid=4025, home=/spool/mail/j/jerry Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: fs: root=/spool/mail/j/jerry/mail, index=, control=, inbox=/spool/mail/j/jerry/mail/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Permission lookup failed from /spool/mail/j/jerry/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Using permissions from /spool/mail/j/jerry/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Permission lookup failed from /spool/mail/j/jerry/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Using permissions from /spool/mail/j/jerry/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Permission lookup failed from /spool/mail/j/jerry/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Using permissions from /spool/mail/j/jerry/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Permission lookup failed from /spool/mail/j/jerry/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): Debug: Namespace : Using permissions from /spool/mail/j/jerry/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, jerry): +1IXBeVXME58MAAARoVNxQ: msgid=<201107271824.p6RIOPa5020900@backup.>: saved mail to INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Effective uid=9838, gid=3011, home=/spool/mail/s/steve Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: fs: root=/spool/mail/s/steve/mail, index=, control=, inbox=/spool/mail/s/steve/mail/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Permission lookup failed from /spool/mail/s/steve/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Using permissions from /spool/mail/s/steve/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Permission lookup failed from /spool/mail/s/steve/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Using permissions from /spool/mail/s/steve/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Permission lookup failed from /spool/mail/s/steve/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Using permissions from /spool/mail/s/steve/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Permission lookup failed from /spool/mail/s/steve/mail/mailboxes/INBOX Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Debug: Namespace : Using permissions from /spool/mail/s/steve/mail: mode=0700 gid=-1 Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Error: link(/spool/mail/j/jerry/mail/INBOX/u.20423, /spool/mail/s/steve/mail/INBOX/.temp.1311791081.P12412Q2M989550.testmailserver.) failed: Permission denied Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): +1IXBeVXME58MAAARoVNxQ: msgid=<201107271824.p6RIOPa5020900@backup.>: save failed to INBOX: Internal error occurred.

[Dovecot] Problem with client login in 1.2.17
by John O'Brien 27 Jul '11

27 Jul '11

Hi, I have been using CentOS 5.5 with Dovecot 1.0.7. My client apps login with TLS/SSL using an postgres database for username and password authentication. I developed a plugin that added an additional IMAP command. I want to eventually migrate to release 2.0 but have decided to make this a two step process. I have started with 1.2.17 as I hope this would be a smaller step along the way. I have installed 1.2.17 from source an installed.

[Dovecot] sieve, vacation - lda-dupes being ignored?

EVERY time the user checks his mails. I haven't heard any user complaint about this, but perhaps nobody tried this before. I recreated this situation (copy old qpopper message INBOX -> tmpbox -> INBOX) and produced two messages with identical X-UIDL headers, but according to the Wikipedia entry for POP3: Comparison with IMAP Clients that leave mail on servers generally use the UIDL command to get the current association of message-numbers to message identified by its unique identifier. The unique identifier is arbitrary, and might be repeated if the mailbox contains identical messages. This is echoed in RFC1939 (page 11-12) While it is generally preferable for server implementations to store arbitrarily assigned unique-ids in the maildrop, this specification is intended to permit unique-ids to be calculated as a hash of the message. Clients should be able to handle a situation where two identical copies of a message in a maildrop have the same unique-id. So POP3 UIDLs are not guaranteed to be unique, especially if the messages are the same. Perhaps some mail readers are making unwarranted assumptions about the uniqueness of UIDLs: http://www.eggheadcafe.com/software/aspnet/33485042/duplicate-messageiduidl… https://www.ritlabs.com/bt/view.php?id=3599 Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] phantom new message notification
by Stan Hoeppner 26 Jul '11

26 Jul '11

I've developed a phantom new message notification on a single IMAP folder in Thunderbird. I've deleted the Dovecot index files for this problematic folder, and I've deleted the .msf file in the Tbird profile. Neither of which solved the problem. The only other time I've run into something similar was with CONDSTORE quite a long time ago, but that affected all folders, not just one. Any ideas? -- Stan

[Dovecot] drac plugin "net_ip2addr() failed: Operation not permitted"
by Michael Moritz 25 Jul '11

25 Jul '11

Hi, I'm trying to get the drac plugin working (again) but I'm stuck with the following message: Restarting IMAP/POP3 mail server: dovecotEDRAC: net_ip2addr() failed: Operation not permitted This is on a Debian Squeeze box, dovecot version 1.2.15-7, drac version 1.12 Looking at the source it should print the IP in the brackets of net_ip2addr. The fact that it's just empty made me think that I may need to set an environment variable. I tried IP="127.0.0.1" in /etc/default/dovecot and as export but to no avail. Any ideas? Thanks, mimo

[Dovecot] passwd not found
by Erik - versatel 25 Jul '11

25 Jul '11

If I use in dovecot.conf passdb passwd-file { args = /etc/dovecot/vhosts/%d/etc/shadow } userdb static { args = uid=virtual gid=virtual home=/var/mail/vhosts/%d/%u allow_all_users=yes } I get an authorisation failure in my mail.log file. If I use passdb passwd-file { args = /etc/dovecot/vhosts/shadow } userdb static { args = uid=virtual gid=virtual home=/var/mail/vhosts/%d/%u allow_all_users=yes } This works !!! (without the %d) in the passdb passwd-file Than the %d/%u is correctly rewritten in the userdb static. PS I have in the passwd-file the username@domain and the username documented for testing. I think there is some problem with the %d (DOMAIN) How can I check if %d is filled ?? And how can i make different authorisationdirs and files per domain.

Hi, I'm attempting to migrate a Courier-IMAP Server to Dovecto. I've followed the instructions in the Dovecot wiki and converted the indices using the provided perl script. Howevery I'm getting "UIDVALIDITY changed ..." messages in the logfile and some of the test clients list some messages twice. I didn't find much about this issue in the wiki. Any hints? -- Mit freundlichen Grüßen / Best Regards Dominik

[Dovecot] Ubuntu package for dovecot 2.0.x from debian package
by Vincent Richomme 23 Jul '11

23 Jul '11

Hi, I am running a server under Ubuntu 11.04(natty) and I would like to install a 2.x version but unfortunately the only package available is 1.2.15. Of course I could compile and install from sources but I would prefer to handle packages because it's a lot simpler and cleaner. After some research I found some debian packages available here : http://xi.rename-it.nl/debian/pool/testing-auto/dovecot-2.0/ So my question is would it be possible to recompile the source package to make a ubuntu one ? Or maybe could I install directly the debian package (but I suppose dependencies are not the same ...). If someone has already an experience with that and couls share his experience. Still don't understand why distros don't use dovecot 2.x ? Is it considered still as unstable ? Thanks

[Dovecot] Automatic Client Retrieval of Messages
by qmail＠top-consulting.net 23 Jul '11

23 Jul '11

Are there any mail clients that automatically pull in folder contents even though they don't have a subscription to that folder ? I have defined a namespace with subscriptions=yes, hidden=yes and list=yes. There are no subscriptions files for any of the users yet they are still pulling data from the folders in that namespace. What gives ?

[Dovecot] My status
by Timo Sirainen 23 Jul '11

23 Jul '11

Hello list, In case anyone's wondering why I haven't been replying here much lately: 1. I've been busy working (you know, paid work) on full text search indexing redesign. That change was a bigger job than I realized at first (mainly due to virtual mailboxes), so I've been a bit stressed/frustrated over it. I finally finished it today though, so that's over now: http://hg.dovecot.org/dovecot-2.1/rev/7b9978eb6f91 I hope to add Antonio's Solr attachment indexing support to it once I'm a bit less busy. I'm in any case also going to add generic attachment indexing so that CLucene backend can also do it. I've also other work left to do for a few more weeks. 2. My new apartment gets too hot (30C) when it gets over about 22C outside, which is almost daily. So my brain melts in the heat and I don't have energy to do much of anything. But I finally yesterday bought an air conditioning machine, which should solve this problem. I don't know why I didn't buy it weeks ago. So .. I'll try to get back to reading and answering mails next week after I've finished some more work and don't feel like I'm lagging behind too much.

[Dovecot] failed creating protocol instance to play queued url
by Ken Mandelberg 22 Jul '11

22 Jul '11

I run thunderbird (both 3.x and 5.x) against dovecot 2.x and frequently see delays "loading message". I admit to having a very large mailbox and running multiple imap clients. I've turned on thunderbird debugging, and at least one pattern I see in the log during the delays (maybe a minute long) is the failed protocol message above. These are no the only delays, but are the ones that catch my eye. The thunderbird debug logs are not time stamped (that I can tell), so its difficult to go back and find the delays from the log. Here is an example of one of the delays.

[Dovecot] Dovecot2 Antispam plugin questions
by Steve Fatula 22 Jul '11

22 Jul '11

Tried to find some doc on this (other than the c code), couldn't, so, asking. I do almost every programming language, except C! When using DSPAM backend with this tool, will the plugin send ONLY the signature and not the entire message to dspam for retraining? Concerned about very large emails. If this is the case, I'd rather do this than use say the mailtrain backend which I presume would send the entire message. Having some permission problems though with the dspam binary since regular users can't execute dspam the way it is currently set up. Any security reason to not allow regular users to run the binary?

[Dovecot] Shared folders and home directories
by Christian Lerrahn 21 Jul '11

21 Jul '11

Hi, I've recently migrated a server from a Qmail/VPOPMail setup to a Postfix/system accounts setup. Everything worked pretty much out of the box after just changing the passdb and userdb to pam and passwd. However, I cannot get my shared folders to work. In the logs I will always see something like Jul 21 07:24:10 mybox dovecot: IMAP(foobar): Namespace 'shared/': Could not lookup home for user bla Jul 21 07:24:11 mybox dovecot: IMAP(foobar): userdb lookup: connect(/var/run/dovecot/auth-master) failed: No such file or directory Now, I don't understand why I need auth-master to find the home directory of user "bla" (who owns the shared folder). However, even if I configure auth-master, only the error messages will go away but I still can't see the shared folders. The configuration (as shown below) worked fine with vpopmail and is just taken from http://wiki.dovecot.org/SharedMailboxes/Shared . What do I have to change to make this work with passwd instead? Do I really need auth-master? If yes, how do I need to set it up to do the job properly?

[Dovecot] %w variable is missing
by Tom Sommer 21 Jul '11

21 Jul '11

Hi, I just noticed that the %w variable is now empty, after upgrading to version 2.0.11? I can still find references to it in the documentation, and in doc/wiki/Variables.txt - but the variable is empty and I can't find any references to it in the sourcecode. Was it overlooked or has it been removed? I'm in need of it :) Thanks. // Tom

[Dovecot] POP3 vs. IMAP Load/Memory usage in Dovecot 1.0.15
by lists＠truthisfreedom.org.uk 21 Jul '11

21 Jul '11

Hi all, We've just provisioned a new cluster of dovecot nodes running Centos and Dovecot 1.0.15 (we needed to match the original configuration, we're upgrading to 1.2 next week!). The nodes are currently equally allocated (50/50 split) to IMAP and POP3, with the intention to move them into a single cluster hosting both services in the next month. All the servers are of identical spec (24 cores, 24G RAM) and are configured to load the indices, control files and maildirs via NFS. We have noticed that the IMAP servers appear to be under much less load and utilising drastically less RAM than the POP3 servers and I'm wondering if there is a reason for this as we have seen some swapping onto disk yet we are only handling 500 concurrent POP3 connections to each server at any given time compared with over 600 IMAP connections. I'm wondering if we've missed a config flag somewhere or (better still!) this issue will go away when we upgrade to 1.2. If anyone can shed any light on this, that would be much appreciated. Thanks in advance, Matt

[Dovecot] dovecot2 on Snow Leopard trouble
by Denis J. Cirulis 20 Jul '11

20 Jul '11

Hello list, I have one task to complete - to install and configure imap server on Mac Mini OS X 10.6.8. I'm not new to dovecot, so the favorite imap server is dovecot. Are there any special settings running dovecot on OS X ? I've compiled dovecot 2.0.13 with mysql5 and openssl via macports. Configured virtual users from mysql and turned on all debug, but when I connect to this server via MUA I'm receiving the message "Mailbox locked. Next try in XX seconds" or something like that. No errors in dovecot.log, clean auth process, correct data (passwords,spool dirs) from mysql. Same configuration works on Linux,FreeBSD and Solaris like a charm. What can be a problem running on OS X ?

[Dovecot] Performance with 200k messages in Maildir
by Vegard Svanberg 20 Jul '11

20 Jul '11

What should I expect performance-wise if I put 200000 messages in a Maildir store and use two or three MUAs (mutt and Thunderbird), on an Athlon dual core 2GHz with SATA drives in software RAID (Linux)? Like; would it be useless/crawling, usable or pretty fast. I imagine MUA startup / first time folder read would be slow, but daily use more or less ok. Thanks to Dovecot's indexing, I imagine I would be better off interfacing Mutt to Maildir via IMAP and Dovecot rather than accessing Maildir/ directly? -- Vegard Svanberg <vegard(a)svanberg.no> [*Takapa@IRC (EFnet)]

[Dovecot] passwd not found
by Erik - versatel 20 Jul '11

If I use in dovecot.conf passdb passwd-file { args = /etc/dovecot/vhosts/%d/etc/shadow } userdb static { args = uid=virtual gid=virtual home=/var/mail/vhosts/%d/%u allow_all_users=yes } I get an authorisation failure in my mail.log file. If I use passdb passwd-file { args = /etc/dovecot/vhosts/shadow } userdb static { args = uid=virtual gid=virtual home=/var/mail/vhosts/%d/%u allow_all_users=yes } This works !!! (without the %d) in the passdb passwd-file Than the %d/%u is correctly rewritten in the userdb static. PS I have in the passwd-file the username@domain and the username documented for testing. I think there is some problem with the %d (DOMAIN) How can I check if %d is filled ?? And how can i make different authorisationdirs and files per domain.

[Dovecot] Dovecot 2, Imap service, client_limit
by Steve Fatula 20 Jul '11

20 Jul '11

I see back in November of last year, a thread about using client_limit in the imap service (not imap-login) that would allow each imap process serve more than one connection. Sounded good, until I tried it! When I did, unlike the OP of that thread, I got: dovecot: imap(submit.user): Fatal: setuid(503(submit.user) from userdb lookup) failed with euid=501(links): Operation not permitted (This binary should probably be called with process user set to 503(submit.user) instead of 501(links)) So, it would appear that this does not work. Still, the thread was posting results of their testing even that showed it worked. Sample message within the thread, read for more: http://www.dovecot.org/list/dovecot/2010-November/054893.html I'd love to be able to use a single imap process for more than one connection. Is this still possible, or, not? If so, how? Steve

[Dovecot] Dovecot + Vpopmail quota issues
by qmail＠top-consulting.net 19 Jul '11

19 Jul '11

I can't get dovecot to ignore a certain directory/namespace when calculating quotas. I am running dovecot 1.2.16 with vpopmail configured for quotas. I use the dot (.) as my separator and my user structure is as follows: ../domain.com/user/Maildir for all the user directories I also have for each user: ../domain.com/user/Maildir/Archive which is a symlink to a NFS mounted partition that holds read-only archives In dovecot.conf I have defined them as follows: mail_location = maildir:~/Maildir namespace private { separator = . prefix = ARCHIVE. inbox = no hidden = yes list = yes location = maildir:~/Maildir/Archive } namespace private { separator = . prefix = inbox = yes } This works very well, in as much as I see the Archive namespace and its folders. The problem arises in the fact that Dovecot insists on calculating the 'Archive' namespace/directory storage towards the total storage used. My Quota configuration is as follows: auth default { mechanisms = plain login digest-md5 cram-md5 passdb vpopmail { args = webmail=192.168.1.12 } userdb vpopmail { args = quota_template=quota_rule3=*:backend=%q } ... } plugin { quota = maildir quota_rule = ?:storage=0 quota_rule2 = Archive:ignore quota_rule3 = ARCHIVE:ignore } From what I've read, this is supposed to use the maildirsize file when available or otherwise return no quota. It worked just fine before this new Archive namespace. For a certain user, vpopmail writes the 'maildirsize' file in ../domain.com/user/Maildir/maildirsize and it contains the correct value ( without the /Archive directory ). The problem is that for some reason, something ( I suspect dovecot ) writes a new maildirsize file in ../domain.com/user/Maildir/Archive/maildirsize which also contains the size of Archive. Subsequently, Dovecot adds the two of them up and usually throws me over quota. To test, I have emptied the maildirsize file under Archive and changed its owner to root (perms are 755 ) so that nobody but root can write to it. Dovecot complained right away about it: Jul 19 12:55:21 pop1 dovecot: IMAP(user(a)domain.com): open(/home/vpopmail/domains/B/domain.com/user/Maildir/Archive/maildirsize) failed: Permission denied Despite passing the quota responsibility to vpopmail it seems that Dovecot still tries to update that file. And finally the question... How do I get dovecot to not calculate a quota for that directory/namespace ?

[Dovecot] Problem with zlib plugin and flags
by Jeremy Maryott 19 Jul '11

19 Jul '11

Hi, I'm working on enabling the zlib plugin and compressing most of the mail on my mail server, and I've run into a bit of a problem with doing things as described on the wiki's zlib plugin page (here: http://wiki.dovecot.org/Plugins/Zlib) I'm using Dovecot 1.2.15 and maildir as a mailbox format on Debian 5. I have a script that implements the steps listed at the bottom of the wiki page. The problem has to do with step 5, which recommends that you add a 'Z' flag to each email that you compress so that you don't compress it again. The problem that I ran into is that when you move an email to another mail folder, this flag appears to go away. As a result, my script has compressed some emails that were already compressed, rendering them unreadable by Dovecot. I've mostly solved that problem, and my compression script now runs 'file' and looks to see if it's gzipped already for each file that's a candidate for compression. I'm not sure this is the best solution (it's definitely slower than just checking the filename), so I'm open to better alternatives. Reading http://wiki.dovecot.org/MailboxFormat/Maildir, I see that Dovecot supports 'non-standard fields' specified after normal flags and a comma. It seems like that might be a better place to put the 'Z' flag, if Dovecot won't retain it when places with the normal flags. I'm unsure how the filename would look if it doesn't currently have any flags, though. Would there just be two commas in a row, followed by my non-standard flag? If I haven't missed or misconfigured anything and what I said above is correct, the wiki should be changed so others don't run into the same problems I have. I'm happy to do so, but I didn't want to make any changes without making sure I was right about what was going on. Thanks, Jeremy
