[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] quota-warning.sh not working (lda problem?)
by Thomas Krause 19 Jul '11

19 Jul '11

Hi, I setup a new mailserver with dovecot 2.0.12. Everything is working fine (including quota) - except of sending quota warning mails. When running /usr/local/bin/quota-warning.sh 95 user(a)domain.de manually as root or user vmail, the mail is delivered. content of /usr/local/bin/quota-warning.sh #!/bin/sh PERCENT=$1 USER=$2 logger -p mail.info "$PERCENT% Quota-warning sent to $USER" cat << EOF | /usr/local/libexec/dovecot/dovecot-lda -d $USER -o "plugin/quota=maildir:User quota:noenforcing" From: postmaster(a)domain.de Subject: $PERCENT% Mail quota warning Content-Type: text/plain; charset=ISO-8859-15; format=flowed Content-Transfer-Encoding: 8bit Der Speicherplatz Ihres E-Mail-Postfaches ist zu $PERCENT% gefüllt.

[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

[Dovecot] dovecot 2.0.13 using LDAP and proxying IMAP4 and POP3 to gmail
by Volker Scheuber 18 Jul '11

18 Jul '11

Fellow dovecot users/contributors, I am building a POP3/IMAP4 proxy solution for an enterprise, where users can login with their common username and then they get single sign-on to all kinds of different applications in the backend. Some of these applications are SaaS apps like gmail. For gmail in particular, I want dovecot to solve the following issues for me: 1. be an IMAP4/POP3 proxy in the enterprise, proxying client requests to mail.com. 2. change both username and password from what's coming in from the client to what's being proxied out to gmail. 3. use LDAP for authentication As a prototype, I implemented #1 and #2 using passwd-files and after a few hours of try and error, I got it to work and was able to login with "username" and "password" and was proxied through to gmail with "username(a)gmail.com" and "gmailpassword". Totally awesome. Now I am stuck porting my working prototype from my laptop and passwd-files to my real lab environment and LDAP. I was able to get the authentication to work but that's about it. I can't get dovecot to do the proxying. I searched the mailing list archives and saw other people having similar issues, but that was almost 4 years ago... The most promising thread similar to my requirements and issues was this one: http://www.dovecot.org/list/dovecot/2007-September/025740.html but it was never fully answered nor did the suggestion given to that thread help me with my issue (but I did follow them). Here is my current configuration: dovecot -n # 2.0.13: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32.36-0.5-default x86_64 SUSE Linux Enterprise Server 11 (x86_64) auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no mail_location = mbox:~/mail:INBOX=/var/mail/%n passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap master = yes pass = yes } passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } My ldap configuration is: cat /usr/local/etc/dovecot/dovecot-ldap.conf.ext |grep -v ^##* |grep . hosts = 127.0.0.1:389 dn = cn=user,ou=users,o=config dnpass = password auth_bind = yes auth_bind_userdn = cn=%n,ou=users,o=data ldap_version = 3 base = ou=users,o=data deref = never scope = subtree user_attrs = =home=/var/mail,uidNumber=uid,gidNumber=gid user_filter = (&(objectClass=posixAccount)(uid=%n)) pass_attrs = mail=user,userPassword=password,uid=proxy,=ssl=any-cert,city=host,description=pass,cn=nologin pass_filter = (&(objectClass=posixAccount)(uid=%n)) iterate_filter = (objectClass=posixAccount) default_pass_scheme = CRYPT When connecting to dovecot through an IMAP client (evolution in my case) the dovecot log shows: Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: auth client connected (pid=26601) Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: client in: AUTH1PLAINservice=imapsecuredlip=137.65.156.25rip=164.99.195.4lport=993rport=49203resp=AGFhYmVsbABOMHYzbGwxMjM0NTY= Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: client out: OK1user=aabell Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: master in: REQUEST3762290689266011e9ff0815dea78591a5437731034c14aa Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: ldap(aabell,164.99.195.4): user search: base=ou=users,o=data scope=subtree filter=(&(objectClass=posixAccount)(uid=aabell)) fields=uidNumber,gidNumber Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: ldap(aabell,164.99.195.4): result: gidNumber(gid)=1001 uidNumber(uid)=1001 Jul 16 13:32:17 linux-1hen dovecot: auth: Debug: master out: USER3762290689aabellgid=1001uid=1001home=/var/mail Jul 16 13:32:17 linux-1hen dovecot: imap-login: Login: user=<aabell>, method=PLAIN, rip=164.99.195.4, lip=137.65.156.25, mpid=26604, TLS It doesn't even seem to be recognizing the extra fields I defined in pass_attrs.

[Dovecot] ACL/shared-folder and Thunderbird
by Christian Roessner 17 Jul '11

17 Jul '11

Hi, I still have some problems with thunderbird and Dovecot. I added ACL/shared-folders to dovecot. While everything is working perfectly under Apple Mail and roundcube, thunderbird behaves very strange. What I did: 1. Step I have three mail accounts set up in thunderbird. In the second and third account I managed IMAL-ACLs on the INBOXes, with following flags: eilrwtsd 2. Step At the first account, I chose IMAP subscriptions and I added both INBOXes (shared/.../INBOX) 3. Step Accounts were shown under shared. The folder shared and one level under shared was wriiten in italic. The INBOXes were shown as regular. 4. Step Clicking on each INBOX showed the mails. I chose properties and selected to compress each folder, if it shows more than 100 mails. 5. Step Closing Thunderbird and restarting it. Now thunderbird shows error notifications that it could noct find a mailbox named shared/shared and that mailboxes shared/system(a)service.intern and shared/de1001(a)service.intern would not exist. The folders shared and the level beyond now is shown as regular folder. I still can see the mails form the INBOXes. But each time I reopen Thunderbird, I get the same error messages. This is, what dovecot is logging: Jul 17 14:38:51 mx0 dovecot: auth: ldap(shared(a)roessner-net.de): unknown user Jul 17 14:38:51 mx0 dovecot: imap(de10000(a)service.intern): Error: Couldn't create namespace 'shared/' for user shared: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/mdbox/dovecot-quota Jul 17 14:40:51 mx0 dovecot: imap(de10000(a)service.intern): Error: Couldn't create namespace 'shared/' for user shared: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/mdbox/dovecot-quota Jul 17 14:42:49 mx0 dovecot: imap(de10000(a)service.intern): Error: Couldn't create namespace 'shared/' for user shared: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/mdbox/dovecot-quota doveadm config -n # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-33-generic-pae i686 Ubuntu 10.04.2 LTS auth_cache_size = 10 M auth_default_realm = roessner-net.de auth_master_user_separator = * auth_mechanisms = plain login digest-md5 cram-md5 ntlm auth_realms = roessner-net.de auth_verbose = yes lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes mail_access_groups = vmail mail_gid = vmail mail_location = mdbox:~/mdbox mail_plugins = quota mail_privileged_group = mail mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = separator = / } namespace { list = children location = mdbox:%%h/mdbox:INDEX=~/mdbox/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/var/mail/virtual/shared-mailboxes quota = dict:User quota::file:%h/mdbox/dovecot-quota quota_rule = *:storage=300M:messages=20000 quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u recipient_delimiter = + sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = -reject } postmaster_address = postmaster(a)mx0.roessner-net.de protocols = imap pop3 sieve lmtp service auth-worker { unix_listener auth-worker { user = vmail } user = vmail } service auth { unix_listener auth-userdb { group = vmail mode = 0660 } user = vmail } service imap-login { service_count = 0 vsz_limit = 64 M } service lmtp { inet_listener lmtp { address = ::1 port = 24 } } service managesieve-login { service_count = 0 } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { user = vmail } user = dovecot } ssl_cert = </ca/mail.roessner-net.de/newcert.pem ssl_key = </ca/mail.roessner-net.de/newkey.pem userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } verbose_proctitle = yes protocol lmtp { mail_plugins = quota sieve } protocol lda { mail_plugins = quota sieve acl } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 50 mail_plugins = quota imap_quota acl imap_acl } Sorry to bother you once again with dovecot/thunderbird questions.

[Dovecot] dovecot init script
by Brandon Lamb 16 Jul '11

16 Jul '11

Anyone have a working startup script for ubuntu 11.04? Ive used debian forever, but apparently /var/run is now a tmpfs, so there is no dovecot directory on a reboot. Its all brand new to me so I dont know if there is a standard way to have it created on boot (obviously other system scripts are creating directories). I dont even know if this is something that goes in an init.d script or configured elsewhere. I came across something that mentioned systemd and /etc/tmpfiles.d (or something like that) which didnt seem to do anything. Anyway, any help or a point in the right direction would be awesome =D Thanks! Brandon

Hi Timo and List, The Dovecot 2.0.10 changelog includes: * LMTP: For user+detail@domain deliveries, the +detail is again written to Delivered-To: header. I have recipient_delimiter = + set, lmtp_save_to_detail_mailbox=yes is working, however Dovecot 2.0.12 LMTP processes are not adding these headers to messages on delivery. Are there other settings that may potentially conflict with this feature?

[Dovecot] ImapTest and QRESYNC testing
by Norman Maurer 15 Jul '11

15 Jul '11

Hi there, I'm currently working on adding QRESYNC support for james.apache.org/imap (which is a JAVA - based imapserver). For testing I'm currently using ImapTest but I'm currently not really sure it really reflect the RFC. Here are the "problems" I see: * It expect to have the UID param in the FETCH Response if QRESYNC was enabled (I was not able to spot the section were it is stated in the rfc) * EXPUNGE command seems to expect EXPUNGE Responses if QRESYNC was enabled, but from the RFC I think VANISHED is valid also. It even seems to fail when testing again dovecot.. So how much can I trust it when testing QRESYNC ? Thanks, Norman Ps: I'm not good a C at all, so its hard for me to provide patches ;)

[Dovecot] Backup namespace
by qmail＠top-consulting.net 15 Jul '11

15 Jul '11

I use dovecot 1.2.16 and I use . (dot) as the hierarchy separator. My user structure is like so: username/Maildir/.Folder1 username/Maildir/.Folder1.Subfolder The Inbox is right under: username/Maildir/cur & username/Maildir/new My namespace definition for the regular mail is: namespace private { separator = . prefix = inbox = yes } In a separate directory, nfs mounted, I also hold full daily backups of each users entire Maildir. It has the following structure: /archive/username/.14.07.2011/.Folder1 /archive/username/.14.07.2011/.Folder1.Subfolder /archive/username/.15.07.2011/.Folder1 /archive/username/.15.07.2011/.Folder1.Subfolder What I'm trying to do is to make the Backups available to each user in their IMAP. I was thinking of symlinking like this: username/Maildir/Backups --> /archive/username/ Would that work ? What should my namespace look like for this situation ? Is there a better way to do this ?

[Dovecot] authentication problems with pam_mkhomedir
by Defenestrate 14 Jul '11

14 Jul '11

Hi! I'm struggling with pam_mkhomedir. Accounts are stored in LDAP (CentOS Directory Server AKA 389 Directory Server). I am not pre-creating user home directories, and would like to use the pam_mkhomedir module to create the directories on the fly, when a user is authenticated via pop3s. pam_mkhomedir is working for interactive (e.g. SSH logins), but I don't want to require users to login interactively just so their home directory is created. Dovecot version: 1.0.7 dovecot -n output: protocols: pop3s >ssl_cert_file: /etc/pki/tls/certs/mail.ourdomain.tld.pem >ssl_key_file: /etc/pki/tls/private/mail.ourdomain.tld.pem >login_dir: /var/run/dovecot/login >login_executable: /usr/libexec/dovecot/pop3-login >mail_privileged_group: mail >mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u >mail_executable: /usr/libexec/dovecot/pop3 >mail_plugin_dir: /usr/lib64/dovecot/pop3 >pop3_client_workarounds: oe-ns-eoh, outlook-no-nuls >auth default: > verbose: yes > debug: yes > passdb: > driver: pam > args: session=yes dovecot > userdb: > driver: ldap > args: /etc/dovecot-ldap.conf /etc/pam.d/dovecot: authsufficientpam_ldap.so >authrequiredpam_deny.so > > >accountsufficientpam_ldap.so >accountrequiredpam_deny.so > > >passwordsufficientpam_ldap.so use_authtok >password requiredpam_deny.so > > >sessionoptionalpam_ldap.so >sessionrequiredpam_mkhomedir.so skel=/etc/skel umask=0022 > >With the pam_mkhomedir.so line, I see the following in maillog: Jul 14 16:14:26 mail dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=xxx.xxx.xxx.xxx rip=xxx.xxx.xxx.xxx resp=<hidden> Jul 14 16:14:26 mail dovecot: auth(default): client out: CONT 1 Jul 14 16:14:26 mail dovecot: auth(default): client in: CONT<hidden> Jul 14 16:14:26 mail dovecot: auth(default): pam(joe.schmoe,xxx.xxx.xxx.xxx): lookup service=dovecot Jul 14 16:14:26 mail dovecot: auth(default): new auth connection: pid=25209 Jul 14 16:14:26 mail dovecot: auth(default): pam(joe.schmoe,xxx.xxx.xxx.xxx): pam_open_session() failed: Permission denied Jul 14 16:14:28 mail dovecot: auth(default): client out: FAIL 1 user=joe.schmoe Jul 14 16:14:28 mail dovecot: auth(default): client in: AUTH 2 PLAIN service=POP3 secured lip=xxx.xxx.xxx.xxx rip=xxx.xxx.xxx.xxx resp=<hidden> With the pam_mkhomedir.so line commented out: Jul 14 16:15:27 mail dovecot: auth(default): client out: CONT 1 Jul 14 16:15:27 mail dovecot: auth(default): client in: CONT<hidden> Jul 14 16:15:27 mail dovecot: auth(default): pam(joe.schmoe,xxx.xxx.xxx.xxx): lookup service=dovecot Jul 14 16:15:27 mail dovecot: auth(default): client out: OK 1 user=joe.schmoe Jul 14 16:15:27 mail dovecot: auth(default): master in: REQUEST 1 25286 1 Jul 14 16:15:27 mail dovecot: auth(default): ldap(joe.schmoe,xxx.xxx.xxx.xxx): user search: base=ou=People, dc=ourdomain, dc=tld scope=subtree filter=(&(objectClass=posixAccount)(uid=joe.schmoe)) fields=homeDirectory,uidNumber,gidNumber Jul 14 16:15:27 mail dovecot: auth(default): master out: USER 1 joe.schmoe home=/home/joe.schmoe uid=1057 gid=1000 Jul 14 16:15:27 mail dovecot: POP3(joe.schmoe): mkdir_parents(/home/joe.schmoe/mail) failed: Permission denied Jul 14 16:15:27 mail dovecot: POP3(joe.schmoe): Failed to create storage with data: mbox:/home/joe.schmoe/mail:INBOX=/var/spool/mail/joe.schmoe Jul 14 16:15:27 mail dovecot: child 25292 (pop3) returned error 89 Jul 14 16:15:27 mail dovecot: pop3-login: Login: user=<joe.schmoe>, method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, TLS Jul 14 16:19:05 mail dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=xxx.xxx.xxx.xxx rip=xxx.xxx.xxx.xxx resp=<hidden> Any Suggestions?

[Dovecot] Process parameters tuning
by Angel L. Mateo 14 Jul '11

14 Jul '11

Hi, I'm having problems with director and lmtp for delivering messages to my dovecot farm. Also I have a warning like this: doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (5048) doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (2003) So I'm trying to tune processes parameters, but I haven't found a complete description of these parameters. All I've found are examples. Questions are about client_limit, service_count, process_limit and process_min_avail. I think that process_limit and process_min_avail are the maximum of running processes for a service and the minimuf of idle process, respectively. But I don't completely understand what exactly are client_limit and service_count, Service_count means how many times a process is reused. If you configure it as 1 means that every time a process ends its connections, it dies. If you configure as 0, when the connections ends, then the process remains idle waiting for new connections. Isn't it? But what does client_limit means? The number of clients that a process can handle? Then number that can handle concurrently? Can a process handle more than one client concurrently? The documentation at http://wiki2.dovecot.org/LoginProcess simply says: * Otherwise new processes are created only once an existing one's connection count reaches client_limit * Default client_limit * process_limit = 1000*100 = 100k connections Does this mean that a process handle a maximun of client_limit connections concurrently? -- Angel L.

[Dovecot] Director lmtp timeout errors

Hello, I have configured two dovecot servers with director acting as lmtp/imap/pop proxy server with 8 dovecot backend servers. In our test environment we had no problem, but when we migrated to production environment, our mail list server (it delivers mail through lmtp) is having a lot of errors like this: 451 4.4.0 Remote server not answering (DATA output timeout) (in reply to end of DATA command)) I have found this same issue in some posts to this list, but I can't find any solution Any idea? -- Angel L.

[Dovecot] Dovecot 2.0.13 and removing IMAP folders in thunderbird
by Christian Roessner 13 Jul '11

13 Jul '11

Hi, I use Dovecot-2.0.13 with mdbox and Thunderbird (IMAP). I have dozens of imap folders and sometimes I wish to delete several folders: First Problem: If I remove a folder under TB, it get moved to my Trash folder. After that I close TB, which also purges the trash. When I come back, the deleted folder and its content is still there. There is no way to remove it with TB. On the server side I see that the folder is listed under mailboxes/Trash and in the subscriptions file, a last line shows that Trash/foldername is subscribed. If I remove that line and the mailboxes-folder, then TB is happy again. Second problem: If I have two folders a and b, both containing a folder example: a/example b/example I only can delete one folder. By deleting the second one, the IMAP server tells me that there already exists on folder named example. I am not sure, if this is thunderbird or dovecot related, but both problems are really annoying. Am I missing some configuration? Thunderbird is Ubuntu's packaged version 3.1.10. Thanks for any ideas and help in advance and don't get me wrong: I really love dovecot ;-) Best wishes Christian -- Roessner-Network-Solutions Bachelor of Science Informatik 50°34.725'N, 08°40.904'O, Nahrungsberg 81, 35390 Giessen F: +49 641 5879091, M: +49 176 93118939 USt-IdNr.: DE225643613 http://www.roessner-network-solutions.com

[Dovecot] How to turn off "plus" delivery
by gene 13 Jul '11

13 Jul '11

I use a lot of plus-style addresses (me+stuff(a)example.com) except I use underscore as the separator rather than plus (me_stuff(a)example.com) My mail logs are full of messages where dovecot looks for a mailbox named "stuff", fails, then delivers to my inbox. Is there a way to turn that off so that dovecot automatically delivers to my inbox? Thanks!

[Dovecot] Many "Error: Corrupted index cache file /XXX/dovecot.index.cache: invalid record size"
by Florent Bautista 11 Jul '11

11 Jul '11

Hi all, I just joigned this list, so I'm sorry if this problem has already been reported. I'm running Dovecot 2.0.13 on many servers, one for POP/IMAP access, others for LDA, others for authentification only, etc. All servers are accessing a shared file system, based on MooseFS (www.moosefs.org) The FS is mounted using FUSE. All my Dovecot servers have this configuration : mail_fsync = always mail_nfs_index = yes mail_nfs_storage = yes mmap_disable = yes (as adviced for NFS installation). But I'm still getting errors like this in POP/IMAP logs : Error: Corrupted index cache file /my_moosefs_fs/domain/user/indexes/.INBOX/dovecot.index.cache: invalid record size Sometimes my Dovecot LDA repairs these files, but then it happens again... All my servers are running Debian 6 over KVM virtualization. Have you ever encountered this ? Do you think this is a Dovecot problem or MooseFS problem ?

Hi All, We had 15 imap/pop UW-imap servers behind load balancer and mail storage was NFS for almost around ~30,000 users on it. Currently we migrate UW-imap to dovecot with fcntl NFS locking. After migration on dovecot it started error related locking see following error Error: fcntl() failed with mbox file /home/w/a/wahmed/.inbox: No locks available Error: fcntl() failed with mbox file /home/e/d/edurand/.inbox: No locks available Look like my NFS locking getting overload or something its (netapps NFS server) what you suggest to fix this issue ? how uw-imap was working with NFS before ? Appreciate your help. -S

[Dovecot] Dovecot indexes
by Mike Prispan 11 Jul '11

11 Jul '11

Hi, could someone answer my following questions about dovecot indexes? - If I delete dovecot indexes, it recreates them without any problem, right? - If dovecot recreates indexes, it does not affect users (they don't have to download all emails again, seen flag is not lost etc.) or is there any problem? - If I use mail_location = ...:INDEX=MEMORY, it recreates indexes every time dovecot is (re)started, right? Does it have any negative effect except performance/resources? - Is there any difference in indexes for mbox and maildir (related to previous questions)? Thanks Mike

[Dovecot] compressed folder bug
by Giulio Casella 11 Jul '11

I found a strange behaviour in dovecot compressed folder, maybe a bug. It happens only if you have one (and just one!) email in a gz compressed folder. I'm talking about a mbox server. Step to reproduce: - create a new folder, using any client (I think this step is not important, it happens also if tou create this folder server-side). - copy one message (any message) into newly created folder (using your favourite drag-n-drop gesture, saving in that folder using you character client (mutt,...), etc.) - if your client automatically subscribe to newly created folders, unsubscribe from it - On your server "gzip newfolder" - On your client subscribe "newfolder.gz" - Try to access you newfolder This is what I get in logfiles: Jul 11 14:08:08 myhostname dovecot: imap(giulio): Error: Next message unexpectedly lost from mbox file /home/giulio/Mail/testfolder.gz at 9082 (cached) Jul 11 14:08:08 myhostname dovecot: imap(giulio): Error: read(/home/giulio/Mail/testfolder.gz) failed: Invalid argument (uid=1) Jul 11 14:08:08 myhostname dovecot: imap(giulio): Disconnected: Internal error occurred. Refer to server log for more information. [2011-07-11 14:08:08] bytes=2045/23657 The funniest thing is that if I have a folder with more than one message it works like a charm.

[Dovecot] Lots of LMTP errors Remote server not answering (DATA output timeout) (in reply to end of DATA command))

Hello, I have configured two dovecot servers with director acting as lmtp/imap/pop proxy server with 8 dovecot backend servers. In our test environment we had no problem, but when we migrated to production environment, our mail list server (it delivers mail through lmtp) is having a lot of errors like this: 451 4.4.0 Remote server not answering (DATA output timeout) (in reply to end of DATA command)) Proxy and backend servers are not loaded.

[Dovecot] dsync and compressed folders
by Giulio Casella 11 Jul '11

11 Jul '11

I'm trying to migrate my old dovecot server (mbox based) to a new one (maildir based), both are version 2.0.13. I'm using dsync: oldserver# dsync -u username backup ssh root@newserver dsync -u username Everything is working like a charm but when it tries to convert compressed folder I got an error: dsync-local(username): Error: Failed to sync mailbox OldMails/2008.gz: Mailbox isn't a valid mbox file. Both old and new installations support compressed folder via zlib plugin. If I'm not wrong dsync doesn't support compressed folder, does it? And, if so, are there any chances to have dsync support gzip'ed folders in the (near) future? Many thanks in advance, gc -- Giulio Casella giulio at dsi.unimi.it System and network manager Computer Science Dept. - University of Milano

[Dovecot] n00b here -- pop email deletion
by Glenn English 11 Jul '11

11 Jul '11

I'm running Dovecot IMAP and POP3 on Debian. But it look's like it's keeping mail in the user's inbox on the server until it's deleted by the user. I thought POP servers deleted email as soon as it was downloaded, but apparently not, according to dovecot.org. Is there something in the Dovecot conf I can do to get rid of all this redundant crud? I see several conversations on the 'Net about "quotas" that look like they might keep stuff around for a few days or weeks, then delete. That sounds lovely, but I don't understand them enough to try to make it happen. dovecot -n: > # 1.0.15: /etc/dovecot/dovecot.conf > log_timestamp: %Y-%m-%d %H:%M:%S > protocols: imap pop3 > ssl_listen: * > ssl_disable: yes > 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 > login_max_processes_count: 12 > mail_privileged_group: mail > mail_executable(default): /usr/lib/dovecot/imap > mail_executable(imap): /usr/lib/dovecot/imap > mail_executable(pop3): /usr/lib/dovecot/pop3 > 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 > pop3_uidl_format(default): > pop3_uidl_format(imap): > pop3_uidl_format(pop3): %08Xu%08Xv > auth default: > mechanisms: plain login > passdb: > driver: pam > userdb: > driver: passwd > socket: > type: listen > client: > path: /var/spool/postfix/private/auth > mode: 432 > user: postfix > group: postfix -- Glenn English

[Dovecot] IMAP not working remotely
by Ondřej Bouda 09 Jul '11

09 Jul '11

Hello, I am trying to set up Dovecot 2.0.9 on Fedora 14. The problem I would like to ask for resolution is that IMAP is not working when connecting to the server from another network. More precisely: - POP3 is working entirely OK, - IMAP is working OK when clients are connecting using local network addresses, like 192.168.0.100, - when a client connects from outside, thus using remote IP address, or even from the server itself using the remote IP address of the server, the following happens: the client correctly connects, but the server sends no greeting (neither the configured login_greeting nor the server IMAP capabilities) and does not respond to the commands. In the server log, I get the following record a while after trying to connect (and actually trying to login): Jul 08 23:24:16 imap-login: Info: Disconnected: Inactivity (no auth attempts): rip=<remote-server-address>, lip=192.168.0.100 Both routing and firewall are OK. The client really connects to dovecot (hence the log message), as seen from a telnet session: Trying a.b.c.d... Connected to example.tld (a.b.c.d). Escape character is '^]'. (and then nothing else) The most confusing for me is the fact that POP3 is configured quite the same and works fine, as well as IMAP on the local network. I tried to change address in the inet_listener imap configuration, but if a wrong address setting was the cause, the client would not get connected at all. As I have spent a pretty long time unsuccessfully searching for a cause, I am asking for some help. Thanks for your time, Ondrej Bouda dovecot -n output follows: # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.11-83.fc14.x86_64 x86_64 Fedora release 14 (Laughlin) ext4 auth_mechanisms = plain login cram-md5 digest-md5 ntlm disable_plaintext_auth = no first_valid_gid = 502 first_valid_uid = 502 last_valid_gid = 502 last_valid_uid = 502 log_path = /var/log/dovecot login_greeting = Welcome mail_location = maildir:/var/mail/virtual/%d/%n passdb { args = scheme=plain username_format=%u /etc/dovecot/passwd driver = passwd-file } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = dovecot-auth } service imap-login { inet_listener imap { address = * port = 143 } } service pop3-login { inet_listener pop3 { address = * port = 110 } } ssl = no userdb { args = username_format=%u /etc/dovecot/passwd driver = passwd-file } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv }

[Dovecot] auth_username_chars question
by Linda Walsh 08 Jul '11

08 Jul '11

I notice there is a space after the = in the default setting: #auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ Is that space part of the syntax or required? If not, does that mean 'space' is included in the default list of allowed characters? If not, then is the space after the '=' required? -- If not, the implication would seem to be that space is 'ignored'. If that's the case, how does one include 'space' in the list of allowed characters? Also, how does one include the "\" character in the list of allowed characters? I.e. is anything accepted, literally, after the first non-space char after the '=' sign? I.e. any spaces after the first non-space char would be taken as valid character, and '\' would also be a literal character? (not that'd I'd be using windows's clients or anything that would, on occasion, pass "DOMAINAME\user" as the calling user trying to log into a 'user' account....or anything....*ahem*...) Overrode it w/some hard-coded hacks, but would like dovecot to me more robust and handle weird input and do the right thing with it (I know that's always a challenging concept for some people, since the answers and ability to arrive at 'correct' is always 'contextual', and so many people want absolute rules that apply all the time in all cases, but...I think thats a diagnosable psychological condition ;-) ).

[Dovecot] Possible bug in shared namespace variable?
by Tom Clark 08 Jul '11

08 Jul '11

As you would have seen earlier I've created a shared mailbox with the following namespace: namespace { type = shared separator = . prefix = Shared.%%n. location = maildir:/var/vpopmail/domains/%%d/%%n/Maildir:INDEX=~/Maildir/Shared/%%n subscriptions = no list = children } This works perfectly, but for some reason the %%n variable in the location maildir is blank. Everywhere else %%n is used works (e.g. the prefix and INDEX). This means for the shared mailbox under support(a)mailbox.com I get a folder Mailder in the domain folder: /var/vpopmail/domains/mailbox.com/Maildir instead of /var/vpopmail/domains/mailbox.com/support/Maildir. Has anyone else come across this?

[Dovecot] Trash handling?
by Mason Loring Bliss 07 Jul '11

07 Jul '11

Hello, all. I've recently switched over to Dovecot from a long stretch of using Courier IMAP, and there's one thing I don't have working that I'd quite like. With Courier I had a magic trash folder in which things I deleted would live for a specified amount of time, after which they'd be deleted. I see how to get the expiry behaviour I want, but not the magic saving-to-mailbox functionality. lazy_expunge looks similar but not precisely what I want. Is there a default way to get expunged messages moved to a different mailbox but not a different namespace? Thanks in advance for clues. -- Mason Loring Bliss mason(a)blisses.org Ewige Blumenkraft!

[Dovecot] passdb/userdb via UNIX socket?
by Peter Mogensen 07 Jul '11

07 Jul '11

Hi, I've been running some performance tests - especially delivery (LDA and LMTP) and it seems there's room for improvement. At least it would be nice to get rid of the fork() and pipe to deliver LDA and the fork of the checkpasswd script for userdb lookup. I've tried LMTP to not fork deliver (*), but checkpasswd still takes time (ok, maybe because it's written on perl as of now). But I was wondering, why there's no passdb/userdb plugin for talking to a local authentication daemon over a UNIX socket? Have I missed something? Is there a thirdparty patch for this? /Peter *: Using Postfix "virtual" LDA seems much faster than asking Postfix to pipe data to "deliver". ... but then of course, I get no dovecot indexing by the LDA.

[Dovecot] Public Mailbox & ACLs
by Tom Clark 06 Jul '11

06 Jul '11

Hi, I'm having a problem I can't get my head around. I'm trying to setup a public mailbox that is hidden from all users unless granted access through an ACL. My folder structure is (migrated from a Courier IMAP/Qmail server): /var/spool/maildir - main public folder (contains a few .qmail files to redirect mail to the correct subfolder) /var/spool/maildir/Support - support public folder (a public folder rather than a maildir) /var/spool/maildir/Support/.SubFolder1 - support sub folder 1 (a maildir) /var/spool/maildir/Support/.SubFolder2 - support sub folder 2 (another maildir) /var/spool/maildir/System /var/spool/maildir/System/.SubFolder1 /var/spool/maildir/System/.SubFolder2 I couldn't get the namespace working correctly to just have 1 folder called "Shared" (you just got an empty folder when trying to subscribe). I ended up making 2 namespaces below: namespace { type = public separator = . prefix = Shared.Support. location = maildir:/var/spool/maildir/Support:INDEX=~/Maildir/Support subscriptions = no } namespace { type = public separator = . prefix = Shared.System. location = maildir:/var/spool/maildir/System:INDEX=~/Maildir/System subscriptions = no } This allowed me to get the result I was looking for. Using an ACL I get a Shared->Support/System->Subfolders view. However the problem is when a user is not in the ACL they can still see the Shared->Support/System folders (just none of the subfolders) and obviously can't subscribe. Could someone let me know what I am doing wrong and if there is a better way of doing this? Many thanks, Tom

[Dovecot] Problems with acl and shared namespace
by Udo Lembke 06 Jul '11

06 Jul '11

Hi, i'm a dovecot-newbie and also new at this mailinglist. I'm try to configure an mailserver with dovecot2, postfix and postfixadmin. At this time i struggle with acl and shared namespace. My goal is, that every user get an archive-area on an separate storage without quota (quota isn't running yet). With: namespace { type = private separator = / prefix = "archiv/%u/" location = maildir:/var/data/archiv/%d/%n:INDEX=/var/data/indexes/archiv/%u:LAYOUT=fs inbox = no subscriptions = yes list = yes } I see the folder, but i can't subscribe them (with thunderbird, or roundcube). With roundcube i can add a new folder below - so i use the trick autocreate5 = archiv/%u/archiv autosubscribe5 = archiv/%u/archiv This is as workaround ok - or is this a "must be"?. But the user should also be able to share parts of the archiv-mailbox with other users (partly on different domains). If i change the type of namespace to shared, i can't access the archiv-folder. The logfile shows problems with the acl (but also with private namespace): Jun 30 11:15:11 imap(test(a)example.com): Debug: Namespace : type=shared, prefix=archiv/test(a)example.com/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:/var/data/archiv/example.com/test:INDEX=/var/data/indexes/… Jun 30 11:15:11 imap(test(a)example.com): Debug: fs: root=/var/data/archiv/example.com/test, index=/var/data/indexes/archiv/test(a)example.com, control=, inbox= Jun 30 11:15:11 imap(test(a)example.com): Debug: acl: initializing backend with data: vfile Jun 30 11:15:11 imap(test(a)example.com): Debug: acl: acl username = test(a)example.com Jun 30 11:15:11 imap(test(a)example.com): Debug: acl: owner = 0 Jun 30 11:15:11 imap(test(a)example.com): Debug: acl vfile: Global ACL directory: (none) Jun 30 11:15:11 imap(test(a)example.com): Debug: Namespace : Using permissions from /var/data/mail/example.com/test: mode=0700 gid=-1 Jun 30 11:15:11 imap(test(a)example.com): Debug: acl vfile: file /var/data/archiv/example.com/test/dovecot-acl not found Jun 30 11:15:11 imap(test(a)example.com): Debug: autocreate: Failed to create mailbox archiv: Permission denied Jun 30 11:15:11 imap(test(a)example.com): Debug: Namespace archiv/test(a)example.com/: Using permissions from /var/data/archiv/example.com/test: mode=0700 gid=-1 Jun 30 11:15:11 imap(test(a)example.com): Debug: acl vfile: file /var/data/mail/example.com/test/dovecot-acl not found I'm wondering about "...dovecot-acl not found" because dovecot create an file "dovecot-acl-list" : # ls -l /var/data/archiv/example.com/test/ drwx------ 5 dovecot dovecot 4096 30.

[Dovecot] proxying user logged in with master user
by Miguel Cabeça 06 Jul '11

06 Jul '11

Hello, I'm running dovecot 1.2.15 and I'm having a problem proxying a user to another host, when this user is logged in with a masteruser. I have two dovecot servers configured to serve half of the users locally and to proxy the other half to the other host. Proxying is done using the masteruser feature (username*proxy) and it works as expected as the following test shows: # nc localhost 143 * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN AUTH=LOGIN AUTH=GSSAPI] Dovecot ready. 01 LOGIN ist90001 password_for_ist90001 01 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 QUOTA] Logged in ^C And the corresponding log entry: Jul 6 13:10:06 mail1 dovecot: imap-login: proxy(ist90001): started proxying to X.Y.Z.W:143/ist90001*proxy: user=<ist90001>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Jul 6 13:10:09 mail1 dovecot: imap-login: proxy(ist90001): disconnecting 127.0.0.1 The ist90001 is proxied to the other host as expected and as configured. The problem occurs when I try to use another masteruser to log into the server: # nc localhost 143 * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN AUTH=LOGIN AUTH=GSSAPI] Dovecot ready. 01 LOGIN ist90001*super password_for_super_masteruser 01 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 QUOTA] Logged in ^C But this time the user isn't proxied to the other host. Instead he is logged in this host: Jul 6 13:11:14 mail1 dovecot: imap-login: Login: user=<ist90001>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Jul 6 13:11:16 mail1 dovecot: IMAP(ist90001): Connection closed bytes=0/292 Is this the intended behavior or a bug? I was expecting the user to be logged in with the password of the super masteruser, and then be proxied to the other host as it happens when the user is logged in with it's own password. I can provide any configuration details if needed. Best Regards Miguel Cabeça

[Dovecot] Converting from qpopper mbox to dovecot maildir
by list＠airstreamcomm.net 05 Jul '11

05 Jul '11

We have an older mail server using qpopper and the mbox format which we need to update to dovecot and maildir format. I have read through the docs on migrating from mbox to maildir, as well as a few nuggets on how to migrate from qpopper to dovecot, and I was wondering if I could get some suggestions on best practices for this specific migration. Would the built in dovecot conversion plugin be a viable method to migrate users? We will be migrating to dovecot 2.0.12 from qpopper 4.0.5. Thanks.

[Dovecot] Dovecot 2.0.13 problem with LMTP
by Innocenzi, Cinzia 05 Jul '11

05 Jul '11

Hello, we have dovecot 2.0.13 installed in our RHEL5 servers. We use dovecot as a lmtp proxy on the front end mail relays and dovecot for back end lmtp/pop/imap. All our servers have RHEL5.6 64-bit and dovecot 2.0.13 installed, and the back end has also an ext3 mbox file-system mounted. Sometimes we have mails that get stuck on our postfix queue with the following error: Remote server not answering (timeout in DATA input) (in reply to end of DATA command) In our logs we only see the fact that the connection times out after 1 minute and gets disconnected: Jun 22 11:56:53 back-end dovecot: lmtp(3256): Connect from a.b.c.d Jun 22 11:57:53 back-end dovecot: lmtp(3256): Disconnect from a.b.c.d: Connection closed Jun 22 11:56:53 front-end dovecot: lmtp(16397): Connect from a.b.c.d Jun 22 11:57:53 front-end dovecot: lmtp(16397): Disconnect from a.b.c.d: Disconnected for inactivity We've tried to recalculate the mbox quota using "doveadm quota recalc -n ..." command and flushed our mail queue, but the mail still gets stuck on the postfix queue with the same error. It doesn't happen for every single mail, it's random. I'm attaching the output of dovecot -n for both servers. Can you please help us?

[Dovecot] imap idle and concurrent connections
by Wolfgang Rosenauer 05 Jul '11

05 Jul '11

Hi, in my testing dovecot (1.2 in that case) seems to not notify all idling clients about new "recent" mails but only one of them. The others get usually a message about the new number of mails after some time but never recent ones. Only one client gets notified about a new mail. Is that a known issue or something which might be configuration specific? Wolfgang

How to code a Dovecot Storage backend it where I might have to start. Really I don't care if the servers are ever fully consistent other than the fact they both contain the same emails. Of course read status shared would be nice. If that status information is out so be it. "eventually consistent" is a deadly thing to try to aim for. Its a simple fact of what needs to be backed up. If a user is at one physical location all the time and connecting to the same server all the time they will not ever see that the 2 servers are not 100 percent synced. For my usage cases lot of times 100 percent synced will be more wasted effort. Roughly synced will be more than suitable. Of course what I am talking about can be used as an foundation to get data from point a to point b. > > Your replication engine can now work in conjunction with Dovecot to sync > changes between servers as quickly as possible, eg if desired implement > a two phase commit when the LDA delivers new emails, so that all storage > servers confirm they have received the new email.

My sync's due to issues maybe chaos. So both servers may have been running split from each other both received emails the other has not had users accessing them. Both with users in using the web and local email clients. While all that is going on the servers have to sync. This is very much the worst case. I am sane. I am prepared to give up the users ability to change client programs between servers to make it be able to work. So IMAP unique identifies not be replicated ever. Basically any identifier that cannot be based of a server id + a unique number for server be only unique to the server its on. Basically I cannot ensure quickly and most of the time I don't really need that. As long as the email without breakage is not lost in the server for greater than 15 min without reaching person wanting to read it that would be fine for normal operations. This is still faster than exchange working with pop email accounts. Basically Ed W. I am saying this is the worst I can get away with in a working office. I have gone through the protocals I would most likely ever need to use from a business point of view. pop3 I know basically does not really give a stuff if what is hiding behind is multi master or single master. User might receive a few extra emails if they change between servers. Nothing system killing. As long as the user gets the emails in the end that is the important bit if they a copy for each server bad luck at least they got the email. Too many copies is not a issue from business point of view not getting the copy in the first place is an issue. smtp messages directly from multi locations outgoing does not give a stuff. imap4 who ever invented this protocol for what I want todo I fell like strangling. The id system completely sends you to hell. Business point of view this might be a issue if uses change between servers due to having to download everything again. activesync/Z-push Ok nice. ID are 64 char in size with no defined contents. No ascending order no trouble basically. So nothing stopping me doing server_id:then unique number. So that is most mobile devices covered. Message might disappear when moving between not totally synced servers. Message will catch up as syncs do. So from business usage annoying but issue is not long lasting. Ie custom backend on Z-push and mobile devices will work mostly fine with chaos between the storage servers. MAPI is 64 chars to 512 chars. for ID's. Again nothing in protocol stopping server_id:then unique number. Web applications much of a muchness. Since either they will connect to the same server as the http server at each location so be protected or can be hooked onto a new protocol to know they are connecting to a multi server back end and detect if there are issues going on. Mostly as bad as activesync if you change between hosting locations email syncs might not have caught up with you so a message might disappear temp. So only imap4 is requiring syncing so ids are in order. Question does everyone need imap4 server locations to be interchangeable. I know I don't. Since most people out the office either use web mail or activesync. Only in office will be using imap4. Now I cannot see any fast sane way for imap4 for other than make it id only unique to each server and maybe create like imap 5 for multi server with the option to run locally as a imap5 to imap4 converter. Reason you ask server when it synced with X server and you find out that is older than the copies you have you don't replace. So the client is hiding server to server sync issues. Sometimes the best solution is look at everything and see what is limiting you and deprecate it. If we don't need id aligned we don't need real-time connection. We don't need as reliable of an network. So failures are less. I guess everyone who has tried to sync has attempted to battle the imap protocal. I am mostly the first strange person who has said stuff syncing imap and just go straight past its defect and make the storage work. Simple fault in imap design make the complete back end replication a pain in but when it should be so simple. I have decided of someone else wants imap to be synced let that be their problem. Simple each location stores what they receive. and forwards to all other locations as those locations come on line and the other locations do the reverse. I like the idea of natural event syncing. That the items pure naturally sync with each other. No reprocessing to force syncing due to least amount conflicting data created. Possible for pop MAPI and activesync/Z-push todo natural syncing. IMAP the evil thing just does not want to play ball with natural syncing and it wants to set up events of conflicting data. IMAP might force a real-time synced server in some cases. A master server handing out IMAP id numbers for new messages is one possibility so removing the need change id's on the mail after it is stored. If my web interfaces are using something other than IMAP I could possibly say use webmail until fixed. Worst issues I can see is message read status and other times like that. Where user might have marked a message unread at X on one server and at Y time marked it back read on a different server. But these are more niggles. Better to have the users annoyed by minor niggles and working than unable to work because its broken. Dependable replications the more parts you use the more areas you have for failure. So far my research on what is possible seams to be coming out to reasonable. Hopefully once I have this idea fully ironed out I can start getting into code. I rarely code. But this is a true case I have a problem so I have motivation. Peter Dolding

[Dovecot] Exim and Dovecot2 SASL: 435 Unable to authenticate at present
by Sergey Urushkin 04 Jul '11

04 Jul '11

Hi. I had working Exim 4.71 and Dovecot 1.2.9 SASL configuration on Ubuntu Lucid, but needed some features from dovecot2, so I installed 2.0.13 from https://launchpad.net/~carsten-uppenbrink-net/+archive/dovecot2 . Now I get Subj error while trying to authenticate via dovecot auth-client socket. However IMAP auth works fine with 2.0.13 and smtp auth worked fine until upgrade, so I think there is something wrong with dovecot2. Dovecot logs stay empty even with auth_debug*, just one string "auth: Debug: Loading modules from bla...". But here is another information that may help. And if it's needed I can build dovecot myself to ensure that ppa-build isn't guilty. Or debug some another way. Thanks. dovecot -n: # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-31-server x86_64 Ubuntu 10.04.2 LTS auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login apop

[Dovecot] Replication problem I have. And how I think I can get around problem.
by Peter Dolding 04 Jul '11

04 Jul '11

I have two servers in two different locations. Neither what you would call 100 percent safe from being turned off. Most staff use web based email. This backs onto imap server. I do know I will have to deal with contact lists and other items. in that client. Worst part is the link between them may get broken so both servers may be receiving email and back active at the same time. I can see 1 very clear way around this problem. If I accept that the imap ids at each of the server will be that server only. Since users are mostly using webbased they are not going to notice. If they do notice because they have connected to a different domain address stiff bad luck. Now what I need to be able to deal with the problem. 1 a unique server id on each message for the server the message was received on. 1 a unique server receive id for each message as imap like id for service recieved messages for message received directly not synced. 1 logs for messages deleted and changes that are not current server server id. This should be pritty simple todo. Basically 1 log per server flushed when synced with the server it owns to. 1 a sync function that deletes and changes messages that have been deleted or changed at other locations and compares other servers current messages against copies retained at the mirroring location. Now with this. Each new message to each store gets the next imap id along with system wide unique combination of sever id and service receive id. No modifications of already recieved messages ids. Since I am not careing if the imap id are matched between servers. Fairly much able to use a custom for of imap syncing working off the server id's and server receive ids. Of course this solution should be fairly fault torrent. Since each server can directly store any message they receive. Also it should be possible to trace back to what server the message came from in case of spam problems or equal. Now my biggest problem can I attach my own custom attributes to incoming mail to the store and access that information effectively. Since with that information I will be able to do a form of live synced storage. Personally I see imap id design as a defect in protocal since it never allowed server id along with it this is why imap 100 percent synced message stores cannot be run on independent servers with unstable network connects well. Nothing comes without a price. This solution does not require clustered file systems or a constant active connection between servers so able to operate in areas of disruption. It does not block the servers from receiving emails at any time either. Problem is of course is if someone connects a client directly from 1 server to another. Mail will have to be re-downloaded. Also I have to check of z-push/ActiveSync depends on the imap ids being dependable across the network if not most hand held devices will not be a problem. If it don't then only imap has a problem. I can live with that. Ie if local email server down use web mail until local mail server is fixed. Old rule of networking 40 to 50 percent functional network staff can normally still get stuff done. 0 percent functional you have downtime. Now if I can get the email storage fault torrent and to remain operational in case of fault I then can focus on getting the web base applications using a equal system for contacts and other things. So each location can remain fairly operational no matter what. This way if a server disappeared for good only thing that would have to be changed is syncing. Wise move is to allow servers to be defined more than 1 server id. Ie a server gone for good remaining server gets told to take over responsibility for the old servers id messages. New replacement server given a new id and everything keeps on going nice. Anyone else with a better idea or advice how to add my own custom ids in a way they cannot be distrupted and are simple to search. If it works push for server id's in imap5? Ie imap5 clients being able to cope with the event that an email store is spreed between multi servers that may not be connected all the time. Peter Dolding

[Dovecot] Dovecot 2.0, mysql and quota

Hello all, I have some troubles to make the quota_check working with dovecot 2.0. My config is the following: postfix, dovecot as lda, mysql as virtual mailuser backend, and postfixadmin for the mailuser administration.

[Dovecot] rsync.dovecot.org
by Timo Sirainen 01 Jul '11

01 Jul '11

Looks like at least some people still want to rsync their own local dovecot.org mirrors, so I've now added rsync support back. Use rsync.dovecot.org as the host. You can rsync: hg dovecotweb dovecotwiki dovecotwiki2 and mbox files of mailing list archives: dovecotmail dovecotnewsmail dovecotcvsmail So for example: rsync -az rsync://rsync.dovecot.org/dovecotweb dovecotweb

[Dovecot] NFS mail storage
by Daniel L. Miller 30 Jun '11

30 Jun '11

The parameters listed for nfs installations (mmap_disable, doctlock_use_excl, mail_nfs_storage, mail_nfs_index) - are they necessary for data integrity, and/or do they compensate for NFS latency and improve performance? My understanding is the indexes are a critical part of a dbox storage, but on the other hand having local indexes is a major performance consideration. Is maildir a "better" choice under NFS than dbox? -- Daniel

[Dovecot] dovecot, mdbox and indexes
by Angel L. Mateo 30 Jun '11

30 Jun '11

Hello everybody, We are updating our old dovecot 1.1 servers to 2.0. We have a farm os servers, with users in nfs filesystems and indexes in local fs. Mail is stored in maildir format. We don't warrant that a user is always directed to the same server, although our load balancer sends all request from one IP to the same server (during a session time with a inactivity timeout). This is the second scenario described at http://wiki2.dovecot.org/NFS. We are now trying to migrate to the third scenario and using mdbox. As an intermediate step, we have configured this second scenario, but with indexes in NFS filesystems. The configuration is: * mmap_disable = yes * dotlock_use_excl = no * mail_nfs_storage = yes * mail_nfs_index = yes * lock_method = fcntl (we have also tried with dotlock) This configuration works without any problems with few users, but with high load, we have a lot of lock timeouts error like: Jun 29 10:24:04 myotis34 dovecot: imap(mpm): Error: Timeout (180s) while waiting for lock for transaction log file /home/pas/01/014601/maildir_indexes/.INBOX/dovecot.index.log These errors cause a corrupted index and we have to manually delete the user's index so he could read his mail again. So we are planning to configure the third scenario. In this configuration, we don't have any problem during our tests if we use maildir format. But if we use mdbox one, we have problems when we have to change the final server for the server (We allways send the user to the same final server, but sometimes, if the server is down, for example, this is not possible). The tests we have done (with POP) are: * I connect to "my" server. There's no problem. I have my mail. I delete a mail. * I connect then to a server that have no index for me. The only problem is that the previously deleted mail appears again. * I connect then to a server with an outdated index: this is the problem. I have only the messages in that outdated index. The mail received since then has disappeared (although I could receive new mail). How could I solve this problem? Is this really a problem? Should I use a shared storage for indexes? What is the best configuration for a high availability service? -- Angel L.

Re: [Dovecot] [Urgent] Email Retrieval from remote servers doesn't use Dovecot

So far I have managed to download emails from Inbox and Sent folder. All the downloaded emails go to single folder 'new' from 'Maildir' directory. Please tell me if there is a way (configuration) to download emails in respective folders. "getmail" appears to support delivery to an arbitrary Maildir folder. See "getmail" documentation. You might want to read up about Maildir to see how it works. In particular you need to know that mail is delivered to a directory "new" (the delivery process involves the directory "tmp", but the message isn't considered delivered until it reaches the directory "new"), but gets moved to a folder "cur" when the Maildir is looked at. So mail could be in either directory "new" or "cur". (The design of Maildir attempts to address various problems, and only partially succeeds, and in other cases makes things worse than they would have been otherwise. But despite its flaws, it still has some strengths, such as reliability, (relative) simplicity, wide support, and the ease by which a message store can be queried/interrogated.) > Also, is there any need for Dovecot now? As I see it, I have managed to download emails from remote servers in maildir format using getmail. How and why would Dovecot fit in? Will Dovecot (via deliver and sieve) assist in segregated email storage (i.e. INBOX in 'new', DRAFTS in '.draft/new' etc). It might be handy to have Dovecot installed as it would mean you could "see into" the mail folders using an IMAP client such as Thunderbird. This will probably make it easier to get a handle on which messages are in which folders than trying to look in the Maildir directories directly. IMAP has a special folder called "INBOX" which appears as the Inbox in most IMAP clients. Under Maildir, in the default location, INBOX can be found at ~/Maildir/{new,cur,tmp} Other folders are mapped into directories, for example the mail folder "Sent" will appear at ~/Maildir/.Sent/{new,cur,tmp} Nested mail folders are flattened into a single directory level in the filesystem, with the folder levels separated by dots, so the mail folder "Projects/PJ1" will appear at ~/Maildir/.Projects.PJ1/{new,cur,tmp} (The above is the default way for Maildir to work. However, Dovecot can be configured to map IMAP folders into Maildir directories in other ways.) Bill

[Dovecot] Problem accessing Dovecot mailing lists via IMAP
by William Blunn 30 Jun '11

30 Jun '11

I recently tried to look at the Dovecot mailing lists through an already-configured IMAP profile, which had worked fine in the past. But it failed saying that the authentication method was not supported. http://www.dovecot.org/mailinglists.html says: "You can get access to the IMAP archives by using *dovecot.org* as the hostname, *anonymous* as the username and an empty password. It's also possible to use ANONYMOUS authentication mechanism if your client supports it (few do)." I noticed that my e-mail client was configured to use the server "imap.dovecot.org", so I changed it to "dovecot.org". But it still complains that the authentication method is not supported. I am using Thunderbird 3.1 over Windows 7 64-bit. Thunderbird was configured for "Password, Transmitted insecurely" (and this option was not working). I have tried the other authentication options available in Thunderbird. "Encrypted password": Does not work; same problem "Kerberos / GSSAPI": Does not work; same problem "NTLM": Does not work; same problem Any ideas? Bill

[Dovecot] what to expect from changing index location
by Davide Vaghetti 30 Jun '11

30 Jun '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everybody, I have one thousand virtual users with mdbox mailbox format and 10 GByte quota. I have noticed some performance problem related to I/O (the mailbox disk is a 6TB raid1+0 on ISCSI), so I want to put the index files on a different disk. My actual mail_location is: mail_location = mdbox:/var/vmail/%-1.1u/%u/mdbox and I want to switch to mail_location = mdbox:/var/vmail/%-1.1u/%u/mdbox:INDEX=/var/indexes/%-1.1u/%u/ But I cannot figure out a pair of things: - - do the switch trigger the rebuilding of the index files? - - can I get rid of all the old index files? - - how much the index files (no fts squat) can grow? thanks in advance bye davide - -- Dott.

[Dovecot] Migrating shared folders from courier-imap to dovecot
by Tom Clark 30 Jun '11

30 Jun '11

Hi, I'm hoping you'll be able to help. I'm working on a project to migrate our users from a courier-imap (4.3.0) based mail server to a dovecot (2.0.8) mail server. I have got all the users migrated and working. However, I can't see how to migrate the shared folders from courier-imap. I have tried to find extra information all the migration information seems to centre around a user mailbox rather than shared mailboxes. Is it simply a case of setting up the shared folders on dovecot, then copying the messages in, finally running the dovecot migration script across them? Any advice would be greatly appreciated. Thanks, Tom

Hi, How do I get the LMTP-server to know which mailbox's are locally hosted and return SMTP code 450 if delivery is attempted to a non local user? I can see that a lookup in the userdb is done, but now matter what I return (1/111) from my checkpassword script I just get: 451 4.3.0 <lp(a)domain.tld> Internal error occurred. Refer to server log for more information. /Peter

[Dovecot] Denying user won't work as expected
by Frank Bonnet 30 Jun '11

30 Jun '11

Hello I tried to use the "deny user" feature but it does not work as expected ... ( dovecot 2.0.12 ) we use LDAP as authentication source I modified the 10-auth.conf file as the following # <doc/wiki/UserDatabase.txt> !include auth-deny.conf.ext #!include auth-master.conf.ext #!include auth-system.conf.ext #!include auth-sql.conf.ext !include auth-ldap.conf.ext #!include auth-passwdfile.conf.ext #!include auth-checkpassword.conf.ext #!include auth-vpopmail.conf.ext #!include auth-static.conf.ext I modified the auth-deny.conf.ext file as the following passdb { driver = ldap deny = yes # File contains a list of usernames, one per line args = /usr/local/etc/dovecot/deny-users } I have tested writting one user (me) in the /usr/local/etc/dovecot/deny-users and the result is the login is denied for ALL users ... If I do not uncomment the !include auth-deny.conf.ext line in 10-auth.conf file everything works well I really need this feature Thanks for any help

Re: [Dovecot] Question about "Storage keeps breaking" in logs
by Maria Arrea 30 Jun '11

30 Jun '11

This dovecot box (RHEL 5.6 x64, dovecot 2.0.13, ext4) is a VM over vmware vsphere. The remote SAN disks are presented via iSCSI to the ESX hosts, and the ESX host show them as "local storage" /dev/sdX We have several VM sharing that datastore, no I/O contention detected. I will try with imaptest but this a production enviroment, I will take a couple of weeks to get a "mainteneance window" for this. Any other idea about this? Maybe this problem is load-related?

[Dovecot] permissions for dbox attachment directory
by imap＠tnde.org 30 Jun '11

30 Jun '11

I am running dovecot 2.0.13 on CentOS5, set up with only local system users, and single instance store set up in a single directory. e.g. mail_attachment_dir = /var/mail/attachments I get errors when importing mail to IMAP because the attachment directories are owned by the respective mail account user(s) and so cannot be accessed or written to by other users. Are there some user id setting I need to change, or do I have to run dovecot with virtual users under a single system account? Thanks!

[Dovecot] Rawlogging uid

Hi, this is my first post to the list after years of passive following every now and then. Dovecot: 2.0.13 (3d07ab746a67) prebuilt binaries from xi.rename-it.nl OS: i686 Debian 6.0 squeeze/sid I am about to run a setup where users are virtual and their mail is owned by vmail user. I bumped into minor client issue and needed to enable rawlogging according to http://wiki2.dovecot.org/Debugging/Rawlog This is what was printed to log at first try: Jun 29 21:46:25 (null)Fatal: This process must not be run as root I changed service postlogin to contain "user = vmail" and above error disapperead. I also tried "user = dovecot" which seem to work as well. Is vmail or dovecot user more appropriate for raw logging? >From wiki I got the impression that user must be same as the effective UID of logged in user, which in my setup is vmail(121). Also, maybe the (null)Fatal -message could be improved(?). # dovecot -n # 2.0.13 (3d07ab746a67): /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-1-686 i686 Debian squeeze/sid ext3 auth_debug = yes auth_verbose = yes debug_log_path = /var/log/dovecot/debug.log first_valid_gid = 123 first_valid_uid = 121 info_log_path = /var/log/dovecot/info.log last_valid_gid = 123 last_valid_uid = 121 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes lmtp_save_to_detail_mailbox = yes log_path = /var/log/dovecot/dovecot.log mail_debug = yes mail_location = maildir:/home/vmail/%n/Maildir 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 namespace { inbox = yes location = prefix = separator = / type = private } passdb { driver = pam } plugin { sieve = /home/vmail/%n/dovecot.sieve sieve_dir = /home/vmail/%n/sieve sieve_extensions = +enotify +subaddress +vacation } protocols = " imap lmtp sieve" rejection_reason = Your message to <%t> was rejected: %r rejection_subject = Mail delivery failed: returning message to sender service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } service imap { executable = imap postlogin } service postlogin { executable = script-login rawlog user = vmail } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = uid=121 gid=123 driver = passwd } userdb { args = uid=121 gid=123 allow_all_users=yes home=/home/vmail/%n driver = static } protocol lda { info_log_path = /var/log/dovecot/lda-info.log log_path = /var/log/dovecot/lda.log mail_plugins = sieve } -- Mikko

Maybe you got NAT forwarding going on where a firewall or other network appliance (like a load balancer) is translating ip1/143 -> ip2/143? Or you're not on the host you think you're on. You can check the dovecot logs to verify that in fact your client is connecting. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Virtual Servers
by Daniel L. Miller 29 Jun '11

29 Jun '11

Maybe a little off-topic - but I hope not too much. Looking for some insight on setting up Dovecot under a virtual server. In particular, I use VirtualBox - and at the moment, Ubuntu Linux. Initial questions on configuration: Caching. It seems to me - and I'm probably wrong - that running a Linux in a VM on a Linux host, there would be a duplication of caching. That is, the host server has a file cache - and the VM, which is otherwise a standard Linux installation, is also going to try to cache its files. This strikes me as a duplication of effort and waste of RAM. Is this something I should devote any time to thinking about and trying to minimize? If so, how? Mail storage. My current mail store is a RAID-10, using the mdbox format. I wish to continue storing the mail on "raw" disks - not place the mail inside a virtual disk. Accordingly, the VM needs to reach the mail outside the VM environment - which according to conventional wisdom means NFS. My initial testing shows NFS results in a dramatically reduced performance for Dovecot. Given that this NFS access is going to be exclusively for Dovecot, and I'm only running a single server, are there any NFS or Dovecot tweaks I should implement? Is there an alternative connectivity for the VirtualBox environment I should explore? -- Daniel

Our objective is to store emails in maildir or mbox format, and process them as part of our research project. --------------------------- Problem: --------------------------- Dovecot works for localhost, but not for remote servers. How do I know? Because thunderbird downloads emails in its default location (specified in settings) and not in maildir or mbox folders. If I send mail to <user>@<system_name> using mail command, dovecot works and thunderbird shows the email stored in maildir folder. But for email from <id>@yahoo.com goes to thunderbird's default folder and are browsed from there. --------------------------- Relevant Technical Details: --------------------------- ps auxw|grep "dovecot\|imap\|pop3" root 1033 0.0 0.0 52796 1916 ?

It is an MRA and we shouldn't be required to install it on remote servers, right? What should I do to make dovecot work for remote servers?

[Dovecot] LDAP timeout
by Bernhard Schmidt 29 Jun '11

29 Jun '11

Hi, we recently hit an issue where one (of the three configured) LDAP servers dropped an index on an attribute due to a misconfiguration, which caused all/most queries for passdb to take a very long time (several 10s of seconds). The other servers would have been fine, but it seems like Dovecot does either not set a timelimit on the query or uses a very high one. I could not find any place to control that either. Is there any knob to tune the LDAP timeout? Bernhard

[Dovecot] Dovecot 1.2.16 -> Dovecot 2.0.13 Performance?
by Jorgen Lundman 29 Jun '11

29 Jun '11

Hello list, Currently running dovecot-1.2.16 as pop, imap, and deliver (with sieve). All on Solaris 10u9, on NFSv4 backends. All is working great. But occasionally, the system gets rather loaded, not entirely sure what part yet, but as part of researching that; If we were to start the upgrade path to dovecot 2.0.13, are there any known areas of performance increase which should encourage us to do this? Since we have a stable system, there is hesitation in changing any part of it :) Each NFS server hosts about 92,381 mailboxes, LDAP as authentication and ZFS user quotas. What sort of numbers do others manage generally?

[Dovecot] Sendmail + dovecot-lda + LDAP
by Василий Яковлев 28 Jun '11

28 Jun '11

Hi, I experince some problems with setting up Sendmail with the LDAP database for virtual mail accounts. Why i'm not writing to the LDAP mailing list? I believe, that the reason of my problem is in configuring dovecot-deliver. What i have: - FreeBSD 8.2-RELEASE - sendmail (Version 8.14.4 with LDAP support installed from ports) - Dovecot LDA + dovecot (as pop3/imap) - 1.2.16 - Cyrus Sasl (authdaemon for authentification) 1. Following http://wiki.dovecot.org/LDA/Sendmail i've set up deliver as LDA. Everything worked fine. 2. Following http://wiki.dovecot.org/HowTo/DovecotOpenLdap i've set up Dovecot to work with tha ldap. Now i can authorize through the client or web interface and get to my maildir. 3. Now, i want my sendmail to accept mail for the account in LDAP database. sendmail.mc: ++++++++++++++++++++++ FEATURE(`local_procmail', `/usr/local/libexec/dovecot/deliver',`/usr/local/libexec/dovecot/deliver -d $u') MODIFY_MAILER_FLAGS(`LOCAL', `-f') ...................................... define(`confLDAP_DEFAULT_SPEC', `-h "localhost" -b "dc=mydomain,dc=ru" -d "cn=dovecot,ou=accounts,dc=mydomain,dc=ru" -MLDAP_AUTH_SIMPLE -P /etc/mail/ldap_pass')dnl LDAPROUTE_DOMAIN(`mydomain.ru')dnl FEATURE(`ldap_routing', `null -T<TMPF>', `ldap -1 -T<TMPF> -v mail -k (&(objectclass=posixaccount)(mail=%0))', `passthru')dnl ......................................

User unknown ++++++++++++++++++++++ It's the problem of the local delivery, i believe. Why? Because after sendmail getting an email it passes it to the LDA, which must check the LDAP (not the passwd!) database for the user, to which this email is send to. Are there some possibilities to solve this problem? I appreciate any help... ----------------------- Best regards, Vasily Yakovlev ----------------------------------------------------------------------

[Dovecot] hide sieve folder from imap clients
by Christopher Stolzenberg 28 Jun '11

Hello, What is the best way to hide sieve folders from IMAP clients? old config mail_home = /var/vmail/%d/%n plugin { sieve_dir = /var/vmail/%d/%n/.sieve/ sieve = /var/vmail/%d/%n/.dovecot.sieve } new config (hide sieve folder) mail_home = /var/vmail/%d/%n maildir_stat_dirs = yes plugin { sieve_dir = /var/vmail/%d/%n/sieve/ sieve = /var/vmail/%d/%n/.dovecot.sieve } Is there a better way without maildir_stat_dirs = yes ? -- Christopher

[Dovecot] ACLs: Group ACL adds empty ACL for user of same name, why?
by Jim Hague 28 Jun '11

28 Jun '11

I'm playing around with ACLs, Groups and SOGo on Debian Stable, Dovecot 1.2.15. If I set an ACL for a group 'developers': 6 setacl "INBOX.Trash" "$developers" "lrsw" 6 OK Setacl complete. The dovecot-acl file for INBOX.Trash then contains a group setting for the group, and a user setting for a user of the same name, giving it no permissions. group=developers lrws user=developers and a subsequent GETACL reports the user: 5 getacl "INBOX.Trash" * ACL "INBOX.Trash" "$developers" lrws "developers" "" "jim" lrwstipekxacd 5 OK Getacl completed. Currently SOGo does not deal well with the unexpected non-existant user. So I'm curious - why's it there? -- Jim Hague - jim.hague(a)acm.org Never trust a computer you can't lift.

[Dovecot] Panic: doveadm quota get -A
by Urban Loesch 28 Jun '11

28 Jun '11

Hi, I'm new to the list and I'm using dovecot since 2 months. Still in progress to migrating from Stalker (Communigate Pro) to Dovecot. Today I upgraded from Dovecot 2.0.13-0~auto+27 (used form the Mirror xi.rename-it.nl - stable-auto) to 2:2.0.13-0~auto+48. List of installed packages: ii dovecot-common 2:2.0.13-0~auto+48 secure mail server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-imapd 2:2.0.13-0~auto+48 secure IMAP server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-lmtpd 2:2.0.13-0~auto+48 secure LMTP server for Dovecot ii dovecot-managesieved 2:2.0.13-0~auto+48 secure ManageSieve server for Dovecot ii dovecot-mysql 2:2.0.13-0~auto+48 MySQL support for Dovecot ii dovecot-pop3d 2:2.0.13-0~auto+48 secure POP3 server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-sieve 2:2.0.13-0~auto+48 sieve filters support for Dovecot It seems all is working fine, except "doveadm quota get -A". It gives me the following error: # doveadm quota get -A doveadm: Panic: file doveadm-print-table.c: line 58 (doveadm_calc_header_length): assertion failed: ((value_count % hdr_count) == 0) doveadm: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x3fd0a) [0x7fb901d0fd0a] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x32) [0x7fb901d0fdf2] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7fb901ce916f] -> doveadm() [0x416bed] -> doveadm(doveadm_print_flush+0x1f) [0x40f1cf] -> doveadm() [0x40a92d] -> doveadm(doveadm_mail_try_run+0x11c) [0x40acfc] -> doveadm(main+0x381) [0x410761] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7fb901581c4d] -> doveadm() [0x409e09] Aborted I also tried the versions 2.0.13-0~auto+45 - 47 from xi.rename-it.nl. Same thing. Have you any idea how i can fix this. Downgrade to a 2.0.13-0~auto+27 is not possible because i have to fix this error to: http://hg.dovecot.org/dovecot-2.0/rev/09b8701362a4 Many thanks and regards Urban Loesch

Thanks. Solaris still uses /usr/lib/sendmail which is a pain since /usr/lib is rarely in shell search paths. Nothing a few symlinks can't fix. Joseph Tam <jtam.home(a)gmail.com>
