[Dovecot] Dovecot 2.0, mysql and quota
by Claudio Prono 01 Jul '11

01 Jul '11

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. Previously i have a working setup with dovecot 1.x, now with the 2.0 something is wrong about the quota, but i don't know what... Here is my config: # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.37.6-0.5-desktop x86_64 openSUSE 11.4 (x86_64) ext3 auth_mechanisms = plain login first_valid_gid = 51 first_valid_uid = 51

[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

( 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

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.

[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?

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 ......................................

[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.

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>

[Dovecot] Maildir parent directory permissions incorrect for new mailbox
by Dominic Marks 28 Jun '11

28 Jun '11

Hi, My issue is with the automatic creation of parent directories above new maildirs. It seems to be that they're being set with incorrect (or unhelpful) permissions, applying the permissions of the mailbox down the path towards the mailbox root, as opposed to taking the permissions of the mailbox root up towards the mailbox. Our mail is stored under the scheme: location = maildir:/var/dovecot/mail/%d/%n:INDEX=/var/dovecot/index/%d/%n Initially, /var/dovecot consists of acl, index and mail, all empty. The permissions on these are: >> ls -l total 6 drwxrwxr-x 2 hmgp hmgp 512 17 Jun 12:23 acl drwxrwxr-x 3 hmgp hmgp 512 17 Jun 15:56 index drwxrwxr-x 3 hmgp hmgp 512 17 Jun 15:56 mail If I perform a mail delivery to my mailbox, the mailbox parent directory is created with the following permissions: >> ls -l total 2 drwx------ 3 dm hmgp 512 17 Jun 15:56 insidetrading.co.uk Note that the user ID is my own and the mode restricts all other access. When I perform a second delivery to different mailbox under that domain, one mapped to a different UID, the delivery fails because that user cannot access the parent folder in order to create the new maildir. I've read on the Wiki that Dovecot copies permissions from the parent directory when adding new messages to a mailbox. That would suit my situation, but it doesn't happen here. Maybe there is there a reason why this is the case? I've had a look at the code and it it works in the opposite direction, starting from the full path (with its associated mode, uid & gid) and working by removing a section from the right-hand side each time. For me, at least, it would be better if it started from the bottom and worked upwards, inheriting the parent uid, gid and mode until the mailbox directory, where the existing behaviour would be retained, looking like: >> ls -dl insidetrading.co.uk/dm total 2 drwx------ 5 dm hmgp 512 17 Jun 15:56 dm I know I could hold all our mail under a single uid/gid or I could fix the mode manually, but I'd rather not do either. Am I missing some key configuration detail or should I work on a patch for this?

[Dovecot] UIDL and message migration
by Hugo Monteiro 28 Jun '11

28 Jun '11

Hello, I'm in the process of migrating accounts between two dovecot servers. An old server running ancient 1.0.15 and a new server running 1.2.15. Account migration is going to be gradual and so i would like to use imapsync to move messages and subscriptions from one server to the other. The only problem so far is with POP users. After doing an account migration with imapsync, and although both servers share the same pop3_uidl_format = %08Xu%08Xv, the client downloads every message that was already on the server. Any pointers would be very much appreciated. Best Regards, Hugo Monteiro.

[Dovecot] problem with dovecot and sieve
by Javier 28 Jun '11

28 Jun '11

Hi We've been using dovecot with great success so far. We are trying to add sieve support for our users. We enabled managesieve and users can define rules from the webmail (roundcube) with sieverules plugin for roundcube. Everything goes ok, but here's a problem I couldn't figure yet. When I define a redirect rule, the mail is forwarded but a local copy is stored too. Weird thing is that the logs say redirecting failed but the mail gets forwarded. Let me show you some of this (personal data masked): # cat .dovecot.sieve ## Generated by Roundcube Webmail SieveRules Plugin ## # rule:[teste] if anyof (true) { redirect "xxxxx@xxxxxxxxx"; } And the log from the user's sieve log sieve: info: started log at Jun 15 18:05:49. error: msgid=<BANLkTik1OzJEreF0qW000OvFpkaR7nOhCQ(a)mail.gmail.com>: failed to redirect message to <xxxxxx@xxxxxxx> (refer to server log for more information). syslog: Jun 16 11:40:26 mailstore5 dovecot: lmtp(8458, xxxxxxx(a)xxxxxx.com) Error: /eMhMNoV+k0KIQAAmtbU9A: sieve: execution of script /var/maildir++/99/xxxxxx(a)xxxxxxxx/.dovecot.sieve failed, but implicit keep was successful (user logfile /var/maildir++/99/xxxxxx(a)xxxxx.com/.dovecot.sieve.log may reveal additional details) And gets redirected anyway Jun 16 11:40:26 mailstore5 postfix/smtp[13041]: CB4D1C79FE: to=<xxxx@xxxxxxx>, delay=0.12, delays=0.02/0/0.01/0.08, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as E24FAB0880) There's no explicit keep anywhere in the sieve rule, nor a global rule, so Im confused, the email should be forwarded only. The error message confuses me too, as it says failed but the mail gets through. dovecot -n # 2.0.9: /opt/mail/dovecot/etc/dovecot.conf # OS: Linux 2.6.36.2 x86_64 Debian 5.0.8 auth_mechanisms = plain login base_dir = /opt/mail/dovecot/var disable_plaintext_auth = no listen = * mail_location = maildir:~/Maildir mail_plugins = create_mbox quota managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include varia passdb { args = socket=/opt/mail/auth_server/var/socket timeout=10 driver = courier } plugin { quota = maildir:User quota quota_rule = Trash:ignore quota_rule2 = Spam:ignore sieve = ~/.dovecot.sieve } protocols = imap pop3 lmtp sieve service imap-login { inet_listener imap { port = 30143 ssl = no } } service lmtp { inet_listener lmtp { address = 0.0.0.0 port = 30024 } process_min_avail = 4 } service pop3-login { inet_listener pop3 { port = 30110 } } ssl = no ssl_parameters_regenerate = 0 userdb { args = socket=/opt/mail/auth_server/var/socket timeout=10 driver = courier } protocol pop3 { mail_plugins = create_mbox quota maildiraccess pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_reuse_xuidl = no pop3_save_uidl = no pop3_uidl_format = %f } protocol imap { mail_plugins = create_mbox quota imap_quota maildiraccess } protocol lmtp { mail_plugins = create_mbox quota sieve } protocol sieve { mail_debug = yes } Your help is appreciated.

[Dovecot] Thunderbird or Dovecot causing duplicates
by Tim 28 Jun '11

28 Jun '11

Hey everyone, back on the list after a few years away. I have a strange issue that is just annoying. Trying to work out if it's Dovecot or Thunderbird causing the problem. Basically, I read an email (so it gets marked as read) and then very quickly I mark is as unread, (i.e. I realised I want to leave that email for later) which causes a duplicate email to be created. Generally I believe both duplicates are then marked as unread, but I've not taken too much notice of that part yet, other than the new email (the duplicate) being marked as unread. This has also happened when deleting emails from a junk folder. It seems to be events happening quickly that ether Thunderbird or Dovecot don't keep up with, so think the state of the message hasn't changed, so recreate the message maybe? I'm not really sure, so was hoping someone else had experienced the issue or could shed some light on it. Thanks Tim The logs from when I managed to recreate this manually this morning as a test.

[Dovecot] %d empty string

My my location is as follows: mail_location = maildir:/var/spool/virtual_mail/%d/%u/Maildir However, when trying to log in the maillog says it can't find /var/spool/virtual_mail//*myusername*/Maildir/cur. As you can see it just uses an empty string for the %d variable. Can anyone help? Thanks, Ryan

[Dovecot] Default sendmail_path value
by Joseph Tam 28 Jun '11

28 Jun '11

It appears the documentation of this parameter is inconsistent with the documentation: > grep -nF /sendmail `gfind src -type f` src/lib-lda/lda-settings.c:41: .sendmail_path = "/usr/sbin/sendmail", src/config/all-settings.c:732: .sendmail_path = "/usr/sbin/sendmail", (and doc/example-config/conf.d/15-lda.conf is also consistent with this) but the documentations states http://wiki2.dovecot.org/LDA sendmail_path is used to send mails. Note that the default is /usr/lib/sendmail, which doesn't necessarily work the same as /usr/sbin/sendmail. I don't know which ought to be changed though. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Help regarding getting password policy response

Hello, I have enabled ldap password policy in my open ldap server and it locks out the account after several unsuccessful bind attempts. I am able to get the password policy response which says "Account locked" by specifying '-e ppolicy' option in my ldapsearch command. I am looking for a way to get similar response when I use dovecot so that I can specify my clients that their account is locked. I understand the security risks involved but mine is low security and high usability requirement. Please share the solution with me. -- Thanks, Sarguru

I can see that dovecot load all plugins from settings, but in the user session, I can get only the plugins that I have selected in mailPlugins field If i check some like this: mailPlugins=mail_plugins=$mail_plugins %$, The imap session user is aborted after login.

[Dovecot] dovecot security with IPv6
by Kārlis Repsons 27 Jun '11

27 Jun '11

Hi Timo, hi all others! In fact, I've only read one person claiming that IPv6 support opens up "too many backdoors" [1], but anyway, as I intend to run just particular services, please give me your opinion if it's insecure to have a dovecot server, which is accessed through a public IPv6 address... (or note just shortly what else could give a firm ground to such claims...) [1] http://forums.gentoo.org/viewtopic-t-882557.html

[Dovecot] Sendmail + dovecot-lda + LDAP
by Василий Яковлев 27 Jun '11

27 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 - sendmail (Version 8.14.4 with LDAP support installed from ports) - Dovecot LDA + dovecot (as pop3/imap) - 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.

[Dovecot] dovecot global sieve script problem
by Dhaval Patel 27 Jun '11

27 Jun '11

I cutover to a new server which uses Postfix & Dovecot to handle emails as opposed to Postfix & Courier in the old server. Below is the contents of my global sieve script and dovecot config info. The dovecot-deliver.log does show that the email is being delivered to INBOX.spam but it ends up in the INBOX instead. If I put the exact same rule in the user script, the emails are delivered into the INBOX.spam folder. Currently as a work around, I created user rules for all users and add this. For most users, it is the only rule. So my question is, why does it not work with the global script? Any help would be appreciated.

[Dovecot] Please help with Quota dict mysql configuration
by Denis Iskandarov 24 Jun '11

24 Jun '11

Hello So what i have: centos 5.6 postfix 2.3.3 dovecot 2.0.13 postfixadmin 2.3.3 roundcube 0.5.3 All general things are working right now i can send receive email with ssl connections etc... Now i'm trying to configure additional options like quota and some other plugins like sieve, trash, expire and deleted-to-trash. Configuration of quota is on first place. I have read wiki regarding quota config , dict config but can't make things running. Hope there are normal sample configs you can share with me. I'm total noob in sql, so it's very difficult for me to arrange stuff in a way i need. My configs: dict { quota = mysql:/etc/dovecot/conf.d/sql/dovecot-dict-sql.conf # expire = sqlite:/etc/dovecot/dovecot-dict-sql.conf } dovecot-dict-sql.conf sample i took from postfixadmin docs provided with package, also changed table to quota2 as suggested for dovecot 2: driver = mysql connect = host=localhost dbname=postfix user=postfix password=postfixadmin default_pass_scheme = MD5-CRYPT table = quota2 select_field = current where_field = path username_field = username my sql.conf i took it from tutorial on your wiki : LDA postfix postfixadmin: driver = mysql connect = host=localhost dbname=postfix user=postfix password=postfixadmin user_query = SELECT concat('/home/vmail/', maildir) as home, concat('maildir:/home/vmail/', maildir) as mail, 1001 AS uid, 12 AS gid, concat('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' #user_query = SELECT maildir, 1001 AS uid, 1001 AS gid, CONCAT('dict:storage=',floor(quota/1000),' proxy::quota') as quota FROM mailbox WHERE username = '%u' AND active='1' password_query = SELECT username as user, password, concat('/home/vmail/', maildir) as userdb_home, concat('maildir:/home/vmail/', maildir) as userdb_mail, 1001 as userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' The second user_query string i took from postfixadmin docs. But i dont know how to aply it. If it is better to use with mysql/postfixadmin and after this all i dont how to configure quota.conf (90-quota.conf): plugin { #quota = dirsize:User quota #quota = maildir:User quota #quota = dict:User quota::proxy::quota #quota = fs:User quota } # Multiple quota roots are also possible, for example this gives each user # their own 100MB quota and one shared 1GB quota within the domain: plugin { #quota = dict:user::proxy::quota #quota2 = dict:domain:%d:proxy::quota_domain #quota_rule = *:storage=102400 #quota2_rule = *:storage=1048576 } Please help me with configuration. I really stuck with this thing. And yes i've tried to find solutions on mailing list, but no luck. I want per domain/user quota in mysql. Also space usage to be shown in roundcube. Hope to get proper help ... And sorry... Thanks in advance.

Hi All, I am trying to achieve ACL set in Public folders, I have public namespace in dovecot.conf like this namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public/ subscriptions = no } and now under public folder I have two subfolders .test and .test1 . I have created dovecote-acl under .test so that it can be seen and subscribe. but I can't see those subfolders in public folder. Logs says Jun 23 17:50:54 node01 dovecot: IMAP(shantanu(a)techblue.co.in): acl: initializing backend with data: vfile Jun 23 17:50:54 node01 dovecot: IMAP(shantanu(a)techblue.co.in): acl: acl username = shantanu(a)techblue.co.in Jun 23 17:50:54 node01 dovecot: IMAP(shantanu(a)techblue.co.in): acl: owner = 0 Jun 23 17:50:54 node01 dovecot: IMAP(shantanu(a)techblue.co.in): acl vfile: file /var/mail/public/.test1/dovecot-acl not found Jun 23 17:50:54 node01 dovecot: IMAP(shantanu(a)techblue.co.in): acl vfile: reading file /var/mail/public/.test/dovecot-acl My dovecot-acl file reads "user=shantanu(a)techblue.co.in lr" It looks I have some problem with my dovecot-acl file, Can anybody please suggest. Thanks in Advance Shantanu

24 Jun '11

Hello Timo, Today I've moved one message from INBOX to a virtual folder which made imap processes crash as soon as INBOX was selected. Jun 24 17:24:50 server dovecot: imap(user(a)example.com): Panic: file mail-index-view.c: line 149 (view_lookup_full): assertion failed: (seq > 0 && seq <= mail_index_view_get_messages_count(view)) Removing mail_log plugin made it working again. Even after re-enabling mail_log plugin there are no crashes anymore. The full backtrace and doveconf -n output are attached. Thanks for your help! -e-frog

[Dovecot] Error with Dovecot LDA when using recipient address misses user part
by Nikolaos Milas 23 Jun '11

23 Jun '11

Hi, We are using Postfix 2.8.3 with Dovecot 2.0.13 on CentOS 5.6. The problem we have is that sometimes, due to mail sender's error when composing a message, the sender attempts to send an email to "@noa.gr" (without specifying the user part of the address). This results in a Postfix error due to Dovecot LDA use: Jun 22 21:05:31 vmail postfix/pipe[31862]: CC89FC4D210: to=<@noa.gr>, relay=dovecot, delay=0.41, delays=0.24/0.013/0/0.15, dsn=5.3.0, status=bounced (command line usage error. Command output: /usr/libexec/dovecot/dovecot-lda: option requires an argument -- d Usage: dovecot-lda [-c <config file>] [-a <address>] [-d <username>] [-p <path>] [-f <envelope sender>] [-m <mailbox>] [-e] [-k] ) Postfix master.cf is configured as: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/dovecot-lda -f ${sender} -d ${user} Obviously this happens because in this case there is no ${user} data. My question is: Can we somehow configure things in a way so as to avoid this error when someone sends an email with blank sender data? Can Dovecot provide some meaningful message to postfix (like "No user specified") instead of failing with a "command line usage error"? Thanks, Nick

[Dovecot] Mysql access denied
by list＠airstreamcomm.net 23 Jun '11

23 Jun '11

Currently using dovecot 2.0.12 and mysql server 4.0.20 (I know, it's really old) and having issues getting Dovecot to authenticate to the mysql server. We have confirmed that the credentials are correct and the host machine can access the database, however we are getting the following error: Jun 23 08:12:50 hostname dovecot: auth: Error: mysql(databaseserver.com): Connect failed to database (database): Access denied for user: 'sqladmin(a)ip.of.host.machine' (Using password: YES) - waiting for 1 seconds before retry We are assuming this has something to do with the password hashing algorithm in older versions of mysql, but we are hoping to confirm this theory and find a solution. Thanks.

[Dovecot] Custom Trash (etc) location
by fusionstream 23 Jun '11

23 Jun '11

Hi there. I have dovecot 1.2.17 installed on me system. I'd like to create a gmail-esque imap tree where all imap folders except for the inbox are in a subdirectory(?). More importantly, I'd like the email client (specifically thunderbird) to be able to recognise the folders and thusly give it a special trash/junk/etc icon which I presume also makes trash and junk go to, well the truash and junk folders automagically. Based on searching the web, I believe that namespaces are the solution. I believed that I had set it up to be 1) Inbox 2) IMAP - Drafts - Junk - Trash - etc However, when trying to use namespaces, I get IMAP.Drafts, IMAP.Junk and all the other folders also appearing in INBOX, in addition to another top-level IMAP.*. What am I doing wrong? If I understand the solutions posted on the web correctly, solving this (resulting in only one of each type of folder) should make thunderbird automagically recognise these "special folders". This is my configuration: # 1.2.17: /etc/dovecot.conf # OS: Linux 2.6.18-238.12.1.el5 i686 CentOS release 5.6 (Final) ext3 ssl_ca_file: /etc/postfix/ssl/cacert.pem ssl_cert_file: /etc/postfix/ssl/smtpd.crt ssl_key_file: /etc/postfix/ssl/smtpd.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login first_valid_uid: *[removed]* last_valid_uid: *[removed]* first_valid_gid: *[removed]* last_valid_gid: *[removed]* mail_location: maildir:/var/spool/mail/virtual/%d/%n mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): autocreate mail_plugins(imap): autocreate mail_plugins(pop3): mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/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 namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes namespace: type: private separator: . prefix: IMAP. list: yes subscriptions: yes lda: postmaster_address: postmaster(a)example.com auth default: mechanisms: plain login user: dovecot-auth passdb: driver: sql args: /etc/dovecot/mysql.conf userdb: driver: sql args: /etc/dovecot/mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 509 user: postfix group: postfix plugin: autocreate: IMAP.Trash autocreate2: IMAP.Spam autocreate3: IMAP.Sent Mail autocreate4: IMAP.Drafts autosubscribe: IMAP.Trash autosubscribe2: IMAP.Spam autosubscribe3: IMAP.Sent Mail autosubscribe4: IMAP.Drafts Any help appreciated.

[Dovecot] Change passwd backend over cron: what happens if changes while reading?
by Denny Schierz 22 Jun '11

22 Jun '11

hi, I want to use two backends für DoveCot. One generated file from the LDAP tree, and the real LDAP. The first backend is generated from a cronjob thats reads the whole ldap server and converts them into a DoveCot passwd file. I red in the Wiki, if the user password isn't correct, than DoveCot asks the second backend (LDAP). Is this correct? Because, the the user can change his password, but Cron generates only every hour the file. So the password in the passwd-file isn't correct, until Cron runs again. The second, what happens, if Dovecot reads the file and in the same moment, Cron generate the new file? Does he change to the second backend? Or do I (the user) get an error? cu denny

[Dovecot] Performance settings for 500-1000User/per day
by Denny Schierz 22 Jun '11

22 Jun '11

hi, we have 2.0.13 running and most works well, but today we had some minor problems: The IMAP login process takes sometimes to much time. Over webmail (Roundcube 0.5.0.3) login wasn't sometimes possible, the normal clients hasn't any problems, until they login. We had only ~ 20-30 active accounts, but 50-60 sessions. The most are Apple products (Ip*/Mac/. ..)because they have 4 sessions or more open. Also we had ~212 processes with: dovenull 2065 4364 0 14:50:32 ? 0:00 dovecot/imap-login vmail 2403 4364 0 14:58:31 ? 0:00 dovecot/imap So, maybe, it's a miss configuration ....

[Dovecot] high number of processes
by Egbert Jan van den Bussche 22 Jun '11

22 Jun '11

Hi, Sometimes a script kiddie tries to guess passwords on our mailserver (Ubuntu 10.04.2 LTS, postfix, dovecot 1.2.9, scanners, the standard stuff). That leads to a nagios message about the high number of processes. The number goes above 500. Nagios threshold is set to 250, which is more than enough for normal operation of this server. When are these processes supposed to die again? They seem to stay at the high count quite long. Is there a way to limit the generation of extra login processes?

Hmm...

Now, most clients seems to handle this extra information message just fine, but it still is annoying me. It doesn't appear all the time, but pretty often...

[Dovecot] Dovecot 2.0.13 and sieve
by Claudio Prono 22 Jun '11

22 Jun '11

Hello all, I am testing Dovecot 2.0.13, with sieve for the vacation. I have some problems with the :regex as i can see... An example: # Sieve Filter # Generato da Ingo (http://www.horde.org/ingo/) (10/06/2011, 04:45:07) require ["vacation", "regex"]; # Vacanze if allof ( not exists ["list-help", "list-unsubscribe", "list-subscribe", "list-owner", "list-post", "list-archive", "list-id", "Mailing-List"], not header :comparator "i;ascii-casemap" :is "Precedence" ["list", "bulk", "junk"], not header :comparator "i;ascii-casemap" :matches "To" "Multiple recipients of*" ) { if header :regex "Received" "^.*(2011) (\$.*\$ )?..:..:.. (\$.*\$ )?(\\+|\\-)....( \$.*\$)?$" { if header :regex "Received" "^.*(Jun) (\$.*\$ )?.... (\$.*\$ )?..:..:.. (\$.*\$ )?(\\+|\\-)....( \$.*\$)?$" { if header :regex "Received" "^.*(10) (\$.*\$ )?...

(\$.*\$ )?(\\+|\\-)....( \$.*\$)?$" { vacation :days 7 :addresses "claudio(a)mediaservice.net" :subject "Test autoresponder" "test autoresponder 22"; } } } } If i test this script with sieve-test, the result is the following: sieve-test .dovecot.sieve new/1307715082.M173915P16839.mail2\,S\=1138\,W\=1168 sieve-test(root): Debug: Effective uid=0, gid=0, home=/root sieve-test(root): Debug: Namespace : type=private, prefix=INBOX., sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/var/mail/virtual//root sieve-test(root): Debug: maildir++: root=/var/mail/virtual//root, index=, control=, inbox=/var/mail/virtual//root sieve-test(root): Debug: none: root=, index=, control=, inbox= Performed actions: (none) Implicit keep: * store message in folder: INBOX sieve-test(root): Info: final result: success No vacation is performed.....

[Dovecot] LIST-EXTENDED support?
by fusionstream 22 Jun '11

22 Jun '11

Hi there. Can I check if LIST-EXTENDED refers to RFC 6154 (http://tools.ietf.org/html/rfc6154) rfc for special use mailboxes. I'd like to specify a designated folder as \Spam and etc. Googling "dovecot list-extended" and "dovecot special use" suggests that dovecot supports this feature (via patch logs and 1 bug report for Mozilla Thunderbird which suggests that dovecot supports this). However when trying to test this feature via thunderbird, it would seem to suggest that it is not currently possible. (Moving folders that Thunderbird has created forces thunderbird to recreate said folder in it's original location) # dovecot --version 1.2.17 Any help/pointers appreciated. Cheers.

[Dovecot] DoveCot LDA/Postfix deliver by address
by Zhou, Yan 21 Jun '11

21 Jun '11

Hi there, I am using DoveCot 1.0.7 and virtual users. We want to integrate with Postfix 2.3.3 to use DoveCot LDA to deliver messages to user mailbox. All users are stored in LDAP. DoveCot looks up user by LDAP access. Our user name is not necessarily part of the address. For instance, address "zhouy@xxxx" may be with user "yzhou", thus all messages to "zhouy@xxxx" should go to /home/vmail/yzhou/Maildir I do not see how LDA can support a two-step lookup: 1. Look up user from the given address, 2. Lookup user mail directory from the user in step 1. My understanding is that /etc/dove-ldap.conf is a one-step lookup, it only does user lookup (without password lookup). Any suggestions?

[Dovecot] DoveCot LDA/Postfix get address rather than user from messages
by Zhou, Yan 21 Jun '11

21 Jun '11

Hi there, We are using Postfix and DoveCot 1.0.7, using DoveCot LDA/Postfix to deliver messages to mailboxes via LDAP lookup. My Postfix 2.3.3 /etc/postfix/master.cf reads like this dovecot unix - n n - - pipe flags=Rhu user=hubdirect argv=/usr/libexec/dovecot/deliver -f ${sender} -d ${recipient} And my /etc/dovecot-ldap.conf reads like this: user_filter = (&(objectClass=DirectUser)(username=%n)) user_attrs = userreference=user,usermaildirectory=mail,userhomedirectory=home I find the above "%n" value in "user_filter" I am getting is always the address, not "user part in user@domain" as the documentation says. Did I miss anything? Thanks, Yan Confidentiality Notice: The information contained in this electronic transmission is confidential and may be legally privileged.

[Dovecot] Dovecot 1.1.20+NFS OS changed issue
by गौरव जोशी 21 Jun '11

21 Jun '11

Hi, I am facing a wierd issue on dovecot while migrating OS of the server. I have CentOS 5.2 32bit OS , Dovecot 1.1.20 with NFS on the server. When I am migrating it to CenOS 5.6 32bit with same Dovecot version. I compiled the same version i.e. 1.1.20 again. Now when I check the number of connection on this new server I can see only 8-10 connections for IMAP and 8-10 for POP3, where on old server I can still see the number of connections crosses 500+. I checked system level configuration which I found identical, limits set to same as old server, still no change in number of connections. I even tried the above exercise on CentOS 5.6 64bit version. again the result is same. I have tried all the changes/configurations I could think of.

[Dovecot] dovecot-metadata-8 released
by Dennis Schridde 20 Jun '11

20 Jun '11

Hello everyone! I just released dovecot-metadata-8, which is an implementation of RFC 5464 (IMAP METADATA), allowing to add comments/annotations/metadata to folders of an email account. The major feature is that it works with Akonadi, or more specifically the Kolab backend thereof, while being dovecot-2.0 compatible. The module consists of 3 plugins, two IMAP frontends and one backend: * "imap-annotatemore" is a partial implementation of draft-daboo-imap- annotatemore-08 (early predecessor to RFC 5464), based on work by Bernhard Herzog (Intevation GmbH). The sole intention is to support Kolab, not to strictly implement the draft. * "imap-metadata" is a complete implementation of RFC 5464. Kolab clients do not (yet) use these commands. * "metadata" is the common backend imap-metadata and metadata were entirely written from scratch, while imap- annotatemore is an adaption of the work by Bernhard Herzog to the new backend. You can download the code via Hg [1] or as exported tarball [2] from the Hg webinterface. Please note that the README is outdated, as are some other files. The build process is pretty much straightforward, just make sure you have the dovecot headers available on your system: ./autogen.sh ./configure --with-dovecot=/path/to/dovecot make make install Next you need to adjust your dovecot config. The following works for me: == dovecot.conf == dict { metadata = file:/var/lib/dovecot/shared-metadata } == 10-mail.conf == mail_plugins = ... metadata == 20-imap.conf == protocol imap { mail_plugins = $mail_plugins ... imap_metadata imap_annotatemore } == 90-plugin.conf == plugin { metadata_dict = proxy::metadata } To allow a Kolab client to find (e.g.) the addressbook folder, issue this IMAP command after login: SETMETADATA "path/to/folder" ("/shared/vendor/kolab/folder-type" "contact") If you find any bugs (crashes, incompatibilities with RFC 5464, etc), please write me a mail. Be advised that this code is still experimental and might crash your server! @Timo: Please have a look at the src/*-ext.[ch] files, they contain extensions to the dovecot libraries and might be useful for others, too. Kind regards, Dennis Schridde [1] http://hg.dovecot.org/dovecot-metadata-plugin [2] http://hg.dovecot.org/dovecot-metadata-plugin/archive/bdf2445e101f.tar.gz

[Dovecot] Gmail like virtual mailboxes
by Aleve Sicofante 19 Jun '11

19 Jun '11

I'm new to this list so let me introduce myself: I'm a computer literate user (I've done some C programming long ago and can run a Linux system and do some light admin), I've never installed a mail server before and I'm in the process of migrating my family and my small business from Gmail (Google Apps) to a virtual server mainly for privacy reasons. I'm in love with Gmail's label system and I just plain hate traditional folders. I use hierarchical labels (as if they were folders but with a message belonging to many at the same time) and that MUST be preserved in the migration. I've looked at Courier's IMAP keywords implementation and it looks good, but everyone on the internet is recommending Dovecot, so here I am. I've tried hard to find information about using unlimited hierarchical labels, virtual mailboxes or any other way of mimicing Gmail's functionality with Dovecot, but I'm lost. First of all: can it be done? If so, is there any introductory documentation? (I've only found very sparse information.) Is it available for any storage format (mbox, maildir, dbox)? Any help will be very appreciated. -- Aleve Sicofante

Vacation (Sieve) replies to the envelope address. However, I have a customer which receive e-mails from a service which sends e-mails on behalf of a user (submitted through a web form). So an e-mail would be like (envelope from and from-header is webformfromwhatever(a)foobar.com) From: webformfromwhatever(a)foobar.com To: mycustomer(a)hisdomain.com Reply-To: usersrealmailaddress(a)example.com I need the reply to go to the reply-to address. Can I handle this with Sieve? -- Vegard Svanberg <vegard(a)svanberg.no> [*Takapa@IRC (EFnet)]

Can I use the .DEFAULT files with global acls to access all mailboxes without explicitly sharing them first? Or must a share be created for every individual mailbox before they will appear in the shared namespace? -- Daniel

[Dovecot] ACL Groups
by Daniel L. Miller 17 Jun '11

17 Jun '11

From the wiki: ACL groups support works by returning a comma-separated acl_groups extra field <http://wiki2.dovecot.org/UserDatabase/ExtraFields> from userdb, which contains all the groups the user belongs to. User's UNIX groups have no effect on ACLs (you can "enable" them by using a special post-login script <http://wiki2.dovecot.org/PostLoginScripting>). I've read that over several times - I still don't understand that. Are "ACL Groups" defined and managed by Dovecot - and described somewhere else in the docs - or are they UNIX groups that previously had no affect on mail access but by being listed in the "acl_groups" field they now have relevance? -- Daniel

[Dovecot] ACL enabled Public folder dovecot
by kumar shantanu 17 Jun '11

17 Jun '11

Hi All, I am trying to do ACL enabled Public folder on dovecot version 1.1.20, but the ACL thing is not working, the public folder is visible and accessible to everyone. My dovecot config for public folder is like ######## namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public subscriptions = no } plugin { acl = vfile } ######### and I have my dovecot-acl file in /var/mail/public/.test which reads ** user=test(a)mydomain.com lrw ** but every user can see the public folders and subscribe to it, which I don't want :( Can someone please suggest. Thanks in Advance, Shantanu

[Dovecot] Converting CLIENT_MAIL_DATA_MAX_INMEMORY_SIZE to a configurable?
by Attila Nagy 17 Jun '11

17 Jun '11

Hi, Currently Dovecot's LMTPd writes incoming emails to mail_temp_dir if it's bigger than 128k. But I would like to spare those unnecessary operations (creating a file, deleting it, writing into it, reading from it, checking whether there is free space and if not, rejecting (temporarily) the message). Memory is cheap, disk IO is not. :) And BTW, on a lot of systems, /tmp is a memory file system already, so there is absolute no need for this. I only fired two greps so far before writing this mail, in the hope that I can spare writing, testing and sending a patch, which will be either rejected, or rewritten. :) So, am I right that the following constant would be needed to be converted into a configurable setting and the task is done? static int client_input_add(struct client *client, const unsigned char *data, size_t size) { if (client->state.mail_data->used + size <= CLIENT_MAIL_DATA_MAX_INMEMORY_SIZE && client->state.mail_data_output == NULL) { buffer_append(client->state.mail_data, data, size); return 0; } else { return client_input_add_file(client, data, size); } } It could be defaulted to 128k, but the user could set it "unlimited" (0 or -1, depending on the author's mood, 0 and/or -1 being unlimited, or 0 being 0, meaning don't even store a bit -doesn't really make sense to me). LMTP is mostly protected from the outside world, so I don't see too much DoS potential here (absolutely not more than in the tmpfs case). Thanks,

[Dovecot] I can't setup namespace per user (with settings keept in sql db)
by Marcin Mirosław 17 Jun '11

17 Jun '11

Hello! I'm trying to setup additional namespace. I'd like to have this setting per user and keep it in postgresql.

Re: [Dovecot] ZFS Filesystem Quota under Solaris 10 and Sparc

The original zfs implementation didn't have user quotas. You could only add quotas to individual file systems as a whole. They apparently added it into the source base in 2009: http://blogs.oracle.com/chrisg/entry/user_and_group_quotas_for but I'm not sure when/if it made it to production. My sol10u8 * (10/09) has it in the man page, but I know some things in the man page isn't in s10 (like sharesmb), so, as they say, ymmv. The current doc for user quotas are here: http://download.oracle.com/docs/cd/E19253-01/819-5461/gazud/index.html If you don't want to use the filesystem quotas, you have to change your rules/configuration to match what dovecot has. See doc/wiki/Quota.Configuration.txt. Hope this helps. -r

[Dovecot] quota_rule beeing ignored and set to system soft! quota
by Leon Meßner 16 Jun '11

16 Jun '11

Hi, originating from the same Problem Edgar Fuß described here [1] about "Zero-sized Maildir files and index corruption on over-quota" i setup quota = fs:user quotas with a quota_rule set to 1.5G to prevent getting those zero sized mail files. What happens now is that when the user is over system soft quota (1G) mails stop beeing delivered. Jun 16 19:05:45 mail dovecot: deliver(elont1): msgid=<20110616185545.05ab0f56@x201t>: save failed to INBOX: Quota exceeded (mailbox for user is full) This is bad as users get notified per mail by a script about beeing over quota (this mail is now beeing deferred). If i don't set a quota_rule i still get 0byte files (quota is ignored). If i set a higher than system quota quota_rule it still uses the system soft quota. I have a seconary mailserver which already uses dovecot 2.x but i can't test the feature there as it's running inside a jail and thus has no access to quota. I would like to keep this machine on 1.2.16 for now. dovecot -n output is below. thanks, Leon [1] http://www.dovecot.org/list/dovecot/2010-October/053554.html 19:20_root@mail:/usr/local/etc# dovecot -n # 1.2.16: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.3-RELEASE-p2 amd64 log_path: /var/log/dovecot.log protocols: imaps pop3s managesieve listen: mail.physik-pool.tu-berlin.de ssl_cert_file: /etc/private/mail.physik.tu-berlin.de.pem ssl_key_file: /etc/private/physik.tu-berlin.de_privatekey.pem login_dir: /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_processes_count: 6 login_max_processes_count: 512 verbose_proctitle: yes first_valid_uid: 200 mail_privileged_group: mail mail_location: maildir:~/maildir mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: 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): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: private separator: / prefix: mail/ location: mbox:~/mail list: yes subscriptions: yes lda: postmaster_address: postmaster(a)physik.tu-berlin.de log_path: info_log_path: mail_plugins: sieve quota quota_full_tempfail: yes sendmail_path: /usr/sbin/sendmail auth default: mechanisms: gssapi plain login krb5_keytab: /etc/mail.krb5.keytab gssapi_hostname: mail.physik-pool.tu-berlin.de worker_max_count: 120 passdb: driver: pam args: session=yes failure_show_msg=yes max_requests=100 userdb: driver: passwd args: blocking=yes plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/.sieve quota_rule: *:storage=15728640 quota: fs:user

[Dovecot] Removal of mailist duplicates?
by Peter Bell 16 Jun '11

16 Jun '11

I am using mpop to fetch mail from my service provider (who use dovecot). I use dovecot to hold all my mail on a local slackware server, with sieve filters, based on 'List-Id', directing mailist postings to their own folders. I use thunderbird to read my mail on an ubuntu desktop. When I receive a reply to a posting I make to a mailist (such as this one), replies I receive are usually sent to me with cc to the list. I would expect, then, to receive the message twice - once in my personal mailbox, and once to the mailist folder. However, this doesn't happen - I only see the posting in the mailist folder. Can anyone tell me at which stage in the process the other message is being supressed? -- ------------------------------------------------------------------- Peter Bell Mob: +63 (0) 9287 340 343 Tagum City, Philippines.

[Dovecot] limiting number of login attempts from same ip
by Jürgen Obermann 16 Jun '11

16 Jun '11

Hello, is it possible to limit the number of pop3 (or imap) login attempts from one IP with dovecot to stop attackers? We recently had an attack from one IP-address lasting 50 minutes that tried 50000 pop3-logins with guessed users and passwords. I know about Fail2Ban but really would prefer an easy to configure solution inside of dovecot. Dovecot has this anvil daemon, can it be used for that purpose? We use dovcot version 2.0.12 under Solaris 10, the pop3-login part of the configuration looking like that: service pop3-login { chroot = login client_limit = 0 drop_priv_before_exec = no executable = pop3-login extra_groups = group = idle_kill = 0 inet_listener pop3 { address = port = 110 ssl = no } inet_listener pop3s { address = port = 995 ssl = yes } privileged_group = process_limit = 0 process_min_avail = 0 protocol = pop3 service_count = 1 type = login user = $default_login_user vsz_limit = 64 M } Thanks, Jürgen -- Hochschulrechenzentrum der | Mail: Juergen.Obermann(a)hrz.uni-giessen.de Justus-Liebig-Universitaet | WWW: http://www.uni-giessen.de/obermann/ Heinrich-Buff-Ring 44 | Tel: 0641-99-13054 (0641-99-13001) D-35392 Giessen, Germany | Fax: 0641-99-13009

Hi, I notice that the Apple patched branch of Dovecot 2.0 with URLAUTH fails to compile on Linux. The file src/plugins/urlauth/urlauth-keys.c uses open(2) with O_EXLOCK, which to my knowledge is BSD specific. Is that a known problem? /Peter

[Dovecot] ZFS Filesystem Quota under Solaris 10 and Sparc
by Jürgen Obermann 15 Jun '11

15 Jun '11

Hallo. Filesystem quotas used to work well under Solaris 9 and ufs filesystems on the Sparc platform even with two rules for the folders in the users home directories /home/group/user and the separate filesystem /var/mail holding the inboxes: plugin { quota = fs:Home-Verzeichnis:noenforcing quota2 = fs:INBOX:noenforcing:mount=/var/mail } Since we upgraded last year to Solaris 10 with zfs filesystems on our Sparc server still using a similar setup with separate filesystems for home directories and inboxes we have no working quota plugin anymore. Currently we use dovecot 2.0.13. Are there any plans or whishes to get the filesystem quota code working again under zfs and Solaris?

[Dovecot] Per-user "Seen" flags on public folder

[Dovecot] Timeout during APPEND
by martin f krafft 14 Jun '11

14 Jun '11

Dear list, I am running dovecot 1.2.15 on a Debian server. One user reports continuous problems synchronising her mailbox via IMAP (offlineimap, via SSH tunnel or SSL socket). It seems that she has a large, locally-created message, but the uplink bandwidth seems to be not enough to push it before dovecot times out the APPEND command. The error/exception happens inside offlineimap's Python imaplib2.py file: APPEND => no response after 30.0 secs I do not know the IMAP protocol all that well, but it seems to me like this is broken somewhere. Could you please help me figure out the problem? -- martin | http://madduck.net/ | http://two.sentenc.es/ "man sagt nicht 'nichts!', man sagt dafür 'jenseits' oder 'gott'." - friedrich nietzsche spamtraps: madduck.bogus(a)madduck.net

[Dovecot] SSL comunication problems with client side.
by Denis Iskandarov 14 Jun '11

14 Jun '11

I can get messages without SSL with no problems. but i need to setup server accept only SSL secured connections. I think my configuration is very proper, but cant find "obvious" problem. Postfix 2.3.3 + dovecot 2.0.13-1_129.el5 + PostfixAdmin 2.3.3 I made own CA. configured postfix and dovecot with same cert key ca. Same public cert i gave for client just converted it to PKCS#12. I cant undestand valid and invalid certs strings in long, they look same. You can check logs and config bellow. Also some other questions regarding SSL: 1. How to make client MUA (thunderbird) automatically retrieve certificate ? My thunderbird cant do it by itself so i'm importing mail cert by myself. 2. If i want to setup Roundcube/Squirrelmail webmail clients with TLS support (https) i have to provide them with same certificates as dovecot and postfix have.

[Dovecot] Sieve question
by Dhaval Patel 14 Jun '11

14 Jun '11

I have successfully setup Postfix -> Dovecot with virtual users and spam filtering with spamassassin. Now the last remaining part is for the user defined rules. Let me describe my environment and what I am trying to achieve. I have Postfix setup to call spamc and deliver to Dovecot according to the master.cf line below. -------------------------------------------------------------- dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/bin/spamc -u vmail -e /usr/lib/dovecot/deliver -d ${recipient} -------------------------------------------------------------- The emails get checked by Spamassassin and are delivered to the users's mailbox (/home/vmail/username). I use an actual username (dhav) and not email address (dhaval(a)example.com) Things are working fine with that. >From reading http://wiki.dovecot.org/LDA/Sieve I see that Sieve can do global and user specified filtering. So I am planning to put the following rule into the global script so spammy emails go to the user's INBOX.spam folder. -------------------------------------------------------------- require "fileinto"; if header :contains "X-Spam-Flag" "YES" { fileinto "spam"; } -------------------------------------------------------------- My first question is, where is this global script? Do I configure the "sieve_global_dir = /etc/dovecot/sieve/"? What about he filename? Most users will not need any additional rules. There are some users that do and I am having a difficult time figuring out how it would be setup. My second question is the following. Is there a way in the global script to check if there is a file called /etc/dovecot/sieve/username or /home/vmail/username/personal_sieve_script and include it? I was using maildrop before this and procmail before that so I apologies for sounding stupid if this is not how Sieve scripts work. I am by no means tied the methods I describe above. If anyone knows of a better way to achieve what I am trying to do, I would appreciate if you let me know of it. Thanks, Dhaval

Hello everybody, I have some basic questions: 1. how can I configure the auto-empty trash plugin for all users after 3 or 4 days (This is very important, regular users do not clean their trash, or are using blackberry and do not have an option to do it or simply, do not care about it) 2. difference between version 1.2.17 and latest 2 version of Dovecot, have the version 2 an automatic option for the trash thing? 3. me as a basic skilled user, how can I made the upgrade to version 2 without major risks, I mean I do not want to leave everybody on my server without mail. I am a novice in all of this stuff, so please excuse me if I am making dumb questions. Thanks in advance for your help.

[Dovecot] Webmail project : to cache or not to cache emails
by Vincent Richomme 13 Jun '11

13 Jun '11

Hi, I plan to develop a new web service where one of its module is a webmail and I am thinking about some implementation details. From a interface point of view I wanted to adopt the same logic a outlook(desktop) or yahoo webmail and not split emails into pages. I mean I just want a single datatable view where user can scroll to see his old messages and data are updated only when user release the vertical scrollbar. When I look at current webmail (roundcube for instance) I can see that a cache is used to stored emails headers and I was wondering if it was really necessary ? Once a user has passed the login process I would like to retrieve only the emails that will be displayed (actually a bit more, I am thinking of 150) but I am wondering if it's a good idea to not use a cache for headers. For instance if I have thousands of users on the same machine, will it support it ? Will it be fast enough ? Of course I will try by myself the different options but would be curious to have some opinions. Thanks

[Dovecot] Explain about (mail_get_first_header(mail, "From", &header)
by Alex Baule 13 Jun '11

Hi Timo... Inside my plugin, i use the (mail_get_first_header(mail, "From", &header) function, to get the email From to put in some Blacklist. Looking in the header under this mail, we have 2 "From" fields. Using the function above, i get the Second "From", but my MTA (exim) look in to The First From, in the First Line, in that way, my blacklist don't work, because the sender to be blocked is different from the From looked by dovecot.

Hi; I installed latest dovecot version (2.0.13) and qmail pathed with qmail-ldap on our systems. We want to use auth_dovecot binary authentication for dovecot.

[Dovecot] Dovecot 2.0+LMTP: Legal MAIL FROM rejected?
by Bernhard Schmidt 13 Jun '11

13 Jun '11

Hi, I run Dovecot 2.0.13 fed by Postfix over LMTP. Today it rejected one mail Postfix and Amavis accepted, generating a bounce. It was just a spammail, but I think the sender address is legal according to RFC5321 and should be accepted. I don't like generating bounces, email should be either rejected by postfix/pre-queue-amavis or delivered. Jun 6 12:32:47 mail postfix/qmgr[840]: 991FC240DB: from=<admin <admin(a)kl38000.com>, size=8427, nrcpt=1 (queue active) Jun 6 12:32:47 mail amavis[27046]: (27046-06) FWD via SMTP: <"admin <admin"@kl38000.com> -> <user(a)domain.com>,BODY=7BIT 250 2.0.0 Ok, id=27046-06, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 991FC240DB Jun 6 12:32:47 mail postfix/lmtp[4710]: 991FC240DB: to=<user(a)vmail.domain.com>, orig_to=<user(a)domain.com>, relay=pop3.domain.com[::1]:24, delay=0.24, delays=0.09/0.11/0.03/0.01, dsn=5.5.4, status=bounced (host pop3.domain.com[::1] said: 501 5.5.4 Invalid parameters (in reply to MAIL FROM command)) It looks like dovecot/lmtp does not accept an address with quoted localpart that contains a space mail from:<"admin admin"@kl38000.com> 501 5.5.4 Invalid parameters mail from:<"adminadmin"@kl38000.com> 250 2.1.0 OK mail from:<"admin<admin"@kl38000.com> 250 2.1.0 OK Bernhard

[Dovecot] Regarding Digest-MD5 auth
by kenja heramba 13 Jun '11

13 Jun '11

Hi, I am writing a Pop3Client. I use dovecot server as POP3 server in linux and hMailServer in windows. I was just testing digest-md5 auth with dovecot server. I had an observation. After server side verification, server sends a verification code to client. If this fails, how can client send the negative response or does it not exist? When I see packet capture, dovecot server sends +OK Logged in for anything client sends. I may be wrong. Please let me know your thoughts Regards, Heramba

[Dovecot] sqlite quota dict
by Nikita Koshikov 13 Jun '11

13 Jun '11

Hello Timo, and list followers, Sqlite supports good feature like mysql 'ON DUPLICATE KEY UPDATE' - it calls REPLACE/INSERT OR REPLACE This clause can be added to INSERT query, like: INSERT OR REPLACE INTO table VALUES() REPLACE INTO table VALUES() // alias to previous one Also this can be done during CREATE TABLE syntax, like so: CREATE TABLE quota ( username text not null, bytes integer not null default 0, messages integer not null default 0, primary key (username) ON CONFLICT REPLACE ); So the examples will work: INSERT INTO quota (bytes,username) VALUES ('112497180','foo(a)spam.dom'); INSERT INTO quota (bytes,username) VALUES ('112497181','foo(a)spam.dom'); SELECT * FROM quota; foo(a)spam.dom|112497181|0 But 1 thing to note - if we updating not all fields and column has NOT NULL DEFAULT value, then DEFAULT value will alter current one: INSERT INTO quota (bytes,username) VALUES ('112497180','foo(a)spam.dom'); INSERT INTO quota (messages,username) VALUES ('1743','foo(a)spam.dom'); SELECT * FROM quota; foo(a)spam.dom|0|1743 This can be easily bypassed if INSERT will be: INSERT INTO quota (bytes,messages,username) VALUES ('112497180','1743','foo(a)spam.dom'); So if dovecot will INSERT values to sql dict in this manner, sqlite can be used for storing quota data.

[Dovecot] virtual users with postfix+dovecot plugin usage question
by Denis Iskandarov 13 Jun '11

13 Jun '11

I'm interested in if i should enable plugins only in LDA as i understood that with postfix dovecot works only like LDA. For example i wanna use autocreate plugin for imap user i have enabled in both IMAP and LDA sections. Is it right or i had to configure it only in LDA section ? Than how quota and imap_quota work in imap section ? For what is it there if lda controls user maildirs ? Dovecot 2.0.13 protocol lda { mail_plugins = quota autocreate } protocol imap { imap_client_workarounds = delay-newmail mail_plugins = quota imap_quota autocreate } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh }

[Dovecot] Question about Dovecot-ACLs
by Jan Phillip Greimann 13 Jun '11

13 Jun '11

Hi there, i try to create an php-script to control acl's for public folders without file-manipulation. For this i use imap_setacl() like this example: imap_setacl($mbox,"INBOX/test", "email(a)domain.tld", "lrwstipekxa"); The acl-file looks so: ~:> cat dovecot-acl user=email(a)domain.tld akxeilprwts But i have a problem with the follow function: imap_setacl($mbox,"INBOX/test", "email(a)domain.tld", ""); This command only delete the rights from the email, not the whole entry in my dovecot-acl file. Now my acl-file looks like this: ~:> cat dovecot-acl user=email(a)domain.tld Did this affect dovecot by any way? Thanks, Jan

Hello, I'm running Dovecot 2.0.13 on my Ubuntu10.04.

[Dovecot] mmap in GFS2 on rhel 6.1
by Aliet Santiesteban Sifontes 13 Jun '11

13 Jun '11

Hello list, we continue our tests using Dovecot on a RHEL 6.1 Cluster Backend with GFS2, also we are using dovecot as a Director for user node persistence, everything was ok until we started stress testing the solution with imaptest, we had many deadlocks, cluster filesystems corruptions and hangs, specially in index filesystem, we have configured the backend as if they were on a NFS like setup but this seems not to work at least on GFS2 on rhel 6.1. We have a two node cluster sharing two GFS2 filesystem - Index GFS2 filesystem to store users indexes - Mailbox data on a GFS2 filesystem The specific configs for NFS or cluster filesystem we used: mmap_disable = yes mail_fsync = always mail_nfs_storage = yes mail_nfs_index = yes fsync_disable=no lock_method = fcntl mail location : mail_location = mdbox:/var/vmail/%d/%3n/%n/mdbox:INDEX=/var/indexes/%d/%3n/%n But this seems not to work for GFS2 even doing user node persistence, maillog is plagged of errors and GFS2 hangs on stress testing with imaptest, many corrupted index for example, transaction logs etc, at this point we have many questions, first mmap... In Redhat GFS2 docs we read: Gold rules for performance: An inode is used in a read only fashion across all nodes An inode is written or modified from a single node only. We have succesfull archived this using dovecot director Now, for mmap rh says: ... If you mmap() a file on GFS2 with a read/write mapping, but only read from it, this only counts as a read. On GFS though, it counts as a write, so GFS2 is much more scalable with mmap() I/O... But in our config we are using mmap_disable=yes, do we have to use mmap_disable=no with GFS2??? Also, how dovecot manage the cache flush on GFS2 filesystem??? Why, if we are doing user node persistence, dovecot indexes gets corrupted??? What lock method do we have to use?? How fsync should be used?? We know we have many questions, but this is really a very complex stuff and we are going to appreciate any help you can give us. Thank you all for a great work, specially Timo... best regards

[Dovecot] Unable to compile --with-mysql on Solaris
by Jesse Reynolds 13 Jun '11

13 Jun '11

Hello I'm hoping someone can give me a pointer as to how to compile Dovecot with MySQL support on Solaris. I am trying to compile dovecot 2.0.13 (also tried 2.0.9) on Solaris (OpenSolaris 2009-06, snv_111b) with the OpenSolaris provided MySQL 5.1.30 under /usr/mysql. The server is a Sun X2100 M2, which has a dual core AMD Opteron processor (amd64). Running "./configure --with-mysql" stops here: ... checking for mysql_config... mysql_config checking for mysql_init in -lmysqlclient... no configure: error: Can't build with MySQL support: libmysqlclient not found the libmysqlclient.so is to be found here: /usr/mysql/5.1/lib/mysql/ or for the amd64 version: /usr/mysql/5.1/lib/amd64/mysql/ And include is at: /usr/mysql/5.1/include/ I have tried various combinations of things in CFLAGS, CPPFLAGS and LDFLAGS, but it doesn't change the configure error above at all.

Re: [Dovecot] postfix dovecot spamassassin question
by Dhaval Patel 12 Jun '11

12 Jun '11

So I setup amavis-new and configured postfix/spamassassin/amavis. Mail is still delivered properly but I do not see the spamassassin info in the headers of the email. I configured amavis-new and set "sa_tag_level_deflt" to -999 so that it would always show up but no luck. I updated the spamassassin config and enabled it. I also tested spamassassin manually running "spamassassin -t < someemail" and that returns the email with the X-Spam in the headers. If this is not the correct place to ask, I apologize. Please direct me where I can find the answer.

[Dovecot] postfix dovecot spamassassin question
by Dhaval Patel 11 Jun '11

11 Jun '11

I have an old server with postfix -> maildrop -> spamassassin -> courier setup. I am installing a new server and would like to use dovecot instead of courier. Currently I have postfix -> dovecot lda -> dovecot setup and emails are delivered as expected. The problem is that I do not know how to get spamassassin integrated into the mix since I am using the dovecot lda rather than maildrop. I would rather keep things as simple as possible and not use maildrop + sendmail just to use spamassasin but will if I have to. So my question to the list is, how do you recommend me doing this? Are there any documentation, howtos or tutorials which can help me configure this? Below is the output of dovecot -n Thanks, Dhaval ------------dovecot -n--------------- # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686-bigmem i686 Debian 6.0.1 xfs log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/ssl/certs/secure.consoe.com.pem ssl_key_file: /etc/ssl/certs/secure.consoe.com.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:/home/vmail/%u mbox_write_locks: fcntl dotlock namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)patel.sh auth_socket_path: /var/run/dovecot/auth-master log_path: /home/vmail/dovecot-deliver.log mail_plugins: sieve global_script_path: /home/vmail/globalsieverc auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail

[Dovecot] Sub-Subfolder from public folders
by Torsten Harenberg 10 Jun '11

10 Jun '11

Dear all, I just moved from an old cyrus instance to a brand new dovecot installation. Everything worked pretty well so far. The only small problem I have is: we have public folders, so I defined namespace { type = public separator = . prefix = public. location = maildir:/var/mail/public:INDEX=%u/public subscriptions = no list = children } And I define ACLs for the folders inside. This works, but the some of these folders have sub-folders and these cannot be seen by (what I have tested is Apple Mail, Thunderbird, Outlook and squirrelmail). File system looks like this: mail# cd /var/mail/public/.icecube-c mail# ls -l .ice* .icecube-hard: total 232 drwxrwxrwx 2 root wheel 512 Jun 9 13:07 cur -rwxrwxrwx 1 root wheel 167 Jun 9 13:07 dovecot-keywords -rwxrwxrwx 1 root wheel 105179 Jun 9 13:07 dovecot-uidlist drwxrwxrwx 2 root wheel 123904 Jun 9 13:07 new drwxrwxrwx 2 root wheel 512 Jun 9 13:07 tmp .icecube-soft: total 2214 drwxrwxrwx 2 root wheel 512 Jun 9 13:06 cur -rwxrwxrwx 1 root wheel 167 Jun 9 13:07 dovecot-keywords -rwxrwxrwx 1 root wheel 1019250 Jun 9 13:07 dovecot-uidlist -rwxrwxrwx 1 root wheel 0 Jun 9 13:06 maildirfolder drwxrwxrwx 2 root wheel 1195008 Jun 9 13:07 new drwxrwxrwx 2 root wheel 512 Jun 9 13:07 tmp mail# ls .icecube-hard .icecube-soft cur dovecot-acl dovecot-keywords dovecot-uidlist new subscriptions tmp Maybe anybody can help with this?

[Dovecot] On-delivery deduplication?
by Xin LI 10 Jun '11

10 Jun '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, A feature of Cyrus-IMAPd I really missed after migrated to Dovecot is their optional "duplicate suppression", which eliminates duplicate message at deliver time, if their envelope sender, recipient and message-id matches. For example, if one subscribes to a mailing list, and someone hit "Reply All" to reply to him, there will be two different SMTP deliveries, one from the replier's server and one from the mailing list. Is it possible to do the same on latest Dovecot? (Looking at the documentation it seems not?) Or is there some better ways to implement the same functionality? Thanks in advance!

[Dovecot] possible bug leading to lmtp crashes
by Trever L. Adams 10 Jun '11

10 Jun '11

I have been using Samba 4 kerberos and ldap with dovecot. Samba 4 changed a while back (resulting in me asking for help) which requires kerberos auth for ldap lookups. My setup worked perfectly before hand. Before and after were with dovecot-2.0.11 and the after also happens with 2.0.11. The only changes were (in my ldap.conf for dovecot -- changes are new lines starting with *, * is not in the conf, just showing changes): hosts = example.org base = dc=example,dc=org ldap_version = 3 user_attrs = userPrincipalName=user user_filter = (&(objectClass=person)(|(mail=%u)(sAMAccountName=%u)(userPrincipalName=%u))) *dn = MACHINEACCOUNT$(a)EXAMPLE.ORG *sasl_bind = yes *sasl_mech = GSSAPI *sasl_realm = EXAMPLE.ORG *#sasl_authz_id = MACHINEACCOUNT$(a)EXAMPE.ORG # For using doveadm -A: iterate_attrs = userPrincipalName=user iterate_filter = (objectClass=person) in dovecot.conf: import_environment = TZ KRB5CCNAME=/etc/dovecot/krb5.cc With that do any of the following lines from the referenced hg rev set mean I am missing anything on my import_environment variable? Or is it all good? 10.15 +/* <settings checks> */ 10.16 +#ifdef HAVE_SYSTEMD 10.17 +# define ENV_SYSTEMD " LISTEN_PID LISTEN_FDS" 10.18 +#else 10.19 +# define ENV_SYSTEMD "" 10.20 +#endif 10.21 +#ifdef DEBUG 10.22 +# define ENV_GDB " GDB" 10.23 +#else 10.24 +# define ENV_GDB "" 10.25 +#endif 10.26 +/* </settings checks> */ 10.27 + 10.28 static const struct master_settings master_default_settings = { 10.29 .base_dir = PKG_RUNDIR, 10.30 .libexec_dir = PKG_LIBEXECDIR, 10.31 + .import_environment = "TZ" ENV_SYSTEMD ENV_GDB, If I am not missing anything, then there seems to be a problem with kerberos sasl with ldap lookups.

[Dovecot] IMAP Label Updates not showing up across shared account
by Ricardo Branco 09 Jun '11

09 Jun '11

Dovecot 2.0.13 Centos 5.4 x86_64 2.6.18-164.9.1.el5 (on ESXi) OS/Logs on local storage, /home all on NFS server for datastore (NFS Store Centos 5.5 x86_64 2.6.18-194.11.1.el5) Thunderbird 3.1.10 on XP/W7 Desktops We are seeing a werid issue where there is a delay of up to a few mins in seeing label updates on messages. I have confirmed that Thunderbird is sending the update to the server with WireShark, its just additional users connected to the same mailbox do not see them. Marking a message as Seen/Un-Seen happens faster just not labels. If you have a label set when you mark a message as Seen/Un-Seen the other clients then see the update straight away. -- The information contained in or attached to this email is intended only for the use of the individual or entity to which it is addressed.

Hi I migrated to dovecot 2 and I started using lmtp for mail delivery. But I have found this on my logs "save failed to INBOX: Not enough disk space" . There is enougth space on disk. and I am not using quota plugin on lmtp my lmtp conf is as follow: # ## LMTP specific settings ## # Support proxying to other LMTP/SMTP servers by performing passdb lookups. #lmtp_proxy = no # When recipient address includes the detail (e.g. user+detail), try to save # the mail to the detail mailbox. See also recipient_delimiter and # lda_mailbox_autocreate settings. #lmtp_save_to_detail_mailbox = no protocol lmtp { # Space separated list of plugins to load (default is global mail_plugins). #mail_plugins = $mail_plugins mail_plugins = sieve postmaster_address = admin(a)domain.tld } Any idea please?

[Dovecot] deliver doesn't find adress/inbox
by Martin Benkenstein 08 Jun '11

08 Jun '11

I'm trying to make dovecot 1.2.15, deliver, openLDAP, exim and fetchmail work together on an Debian Squeeze (virtual) maschine. The connection between dovecot and LDAP seems to be working, I can logon from Thunderbird (IMAP) and my maildir is created automatically. So far so good. But when I download the mails via fetchmail, it seems that deliver cannot find the correct mailbox for the X-Envelope-To entry in the header. fetchmail downloads all mails for the domain from one account (config below) and hands them over to exim. I configured exim addording to the wiki entry (http://wiki.dovecot.org/LDA/Exim Virtual Users / Single UID). The mail is sent back to the account which is fetched by fetchmail. There is a header entry X-Fetchmail-Warning: no recipient addresses matched declared local names. The fetchmail-log itself is worthless. What am I doing wrong? At which does the system try to look up the mailaddress and fails?

[Dovecot] How Dovecot 2 create folders and subfolders ( MBOX format ) with TB ?
by Frank Bonnet 07 Jun '11

07 Jun '11

Hello When creating new IMAP folder with thunderbird and Dovecot configured with the std MBOX format dovecot create a file in mbox format and so it is not possible to create a subfolder of this folder. If you ask to create a NEW subfolder of the form : TOTO/TATA Dovecot create a directory TOTO containing a mbox file TATA. Very useful :-) I suppose the "/" separator is parsed by dovecot then it creates a directory containing the mbox file. Am I right ?

[Dovecot] restore lost emails

07 Jun '11

Hi, I was wondering if anyone might be able to help me with this. I am running Postfix 2.7.0, Dovecot 1.2.9 and squirrelmail. Every week, I perform a back-up on both Postfix and Dovecot (maildir and conf folders). That's good because I have all the emails backed up. And now what I would like to ask is whether or not there are any easy way of restoring e-mails if some emails got deleted by accident or for other reason. So far, I have tried to look up the answer on the Internet but got a bit of vague answer. Any help would be greatly appreciated. Thank you

[Dovecot] Subject: IMAP crash on index
by Ruan Kendall 06 Jun '11

06 Jun '11

I'm running Dovecot 1.2.15 as an IMAP server on an up-to-date Debian v6 VM. I've recently upgraded the server from a pretty crusty old Debian v4 installation, though I don't recall exactly which version of Dovecot that would have been running. I guess I could try crawling through the old logs to check if it is likely to be useful. The upgrade seemed to have gone fine and I've been using the new server for about a week, but this morning I'm finding that whilst I can successfully connect to the IMAP server using Mutt, it can't display a mail index and a quick peek at the logs shows the IMAP process falling over: (account and server IP replaced) Jun 6 10:39:27 xen dovecot: Dovecot v1.2.15 starting up (core dumps disabled) Jun 6 10:39:27 xen dovecot: auth-worker(default): mysql: Connected to localhost (mail) Jun 6 10:39:34 xen dovecot: imap-login: Login: user=<example(a)example.org>, method=PLAIN, rip=::1, lip=::1, TLS Jun 6 10:39:35 xen dovecot: IMAP(example(a)example.org): Panic: file mail-index-view.c: line 264 (view_lookup_seq_range): assertion failed: (first_uid > 0) Jun 6 10:39:35 xen dovecot: IMAP(example(a)example.org): Raw backtrace: imap() [0x80f0e1e] -> imap() [0x80f0e82] -> imap() [0x80f0809] -> imap() [0x80ceb17] -> imap(mail_index_lookup_seq+0x26) [0x80ce5f6] -> imap() [0x80c481d] -> imap(mail_index_modseq_hdr_update+0x2e) [0x80c48ee] -> imap(mail_index_sync_ext_hdr_update+0xbb) [0x80de91b] -> imap(mail_index_sync_record+0x40f) [0x80cd57f] -> imap(mail_index_sync_map+0x2dd) [0x80cdfed] -> imap(mail_index_map+0x5c7) [0x80c3557] -> imap() [0x80bfd87] -> imap(mail_index_open+0x23f) [0x80c01ff] -> imap(index_storage_mailbox_open+0x71) [0x80abc81] -> imap(maildir_storage_sync_init+0x188) [0x8086c18] -> imap(mailbox_sync+0x31) [0x80b59d1] -> imap(imap_status_get+0x8a) [0x806f0ea] -> imap(cmd_status+0x123) [0x8065dd3] -> imap() [0x8067b5c] -> imap() [0x8067c32] -> imap(client_handle_input+0x175) [0x8067eb5] -> imap(client_input+0x5f) [0x80686ef] -> imap(io_loop_handler_run+0xd6) [0x80f9aa6] -> imap(io_loop_run+0x20) [0x80f8f20] -> imap(main+0x5b4) [0x8070f24] -> /lib/i Jun 6 10:39:35 xen dovecot: IMAP(example(a)example.org): 76] -> imap() [0x80603a1] Jun 6 10:39:35 xen dovecot: dovecot: child 20617 (imap) killed with signal 6 (core dumps disabled) I've not been able to find any mentions of this error occurring for other people.

[Dovecot] file rights for dictionary file
by Michael Köhler 06 Jun '11

06 Jun '11

Hi, I use Debian Squeeze and the sources from Stephan Bosch. A few weeks ago I´ve upgraded from 2.0.11 to 2.0.13 and got an error May 29 20:01:53 mailserver dovecot: dict: Error: Can't open configuration file /etc/dovecot/dovecot-dict-sql.conf.ext: Permission denied May 29 20:01:53 mailserver dovecot: dict: Error: Failed to initialize dictionary 'quota' and I could see that /etc/dovecot/dovecot-dict-sql.conf.ext is owning by root:root with 600. After changing to root:root 644 all works, but after each upgrade all files in /etc/dovecot will be set to 600. Is it a problem of the dovecot package or should I do some changes to config to allow dovecot reading the dict file?

[Dovecot] Bug: Fixed a duplicate
by Tom Sommer 06 Jun '11

06 Jun '11

I restored a dovecot mailserver today, and when I started the server again, the logs filled up with "Fixed a duplicate" warnings. This in itself it not a problem, the problem is that it appears the fix is not done correct. Consider this: Warning: Fixed a duplicate: [X]/cur/1305907573.V807I37682f3M146183.mail8.xxx.com:2,S -> 1306601066.M382668P27710.mail8.xxx.com The problem appears to be the timestamp of this new file isn't updated correctly. Now I got hundreds of mailboxes filled with mails named 1305907573.* with random (in the past) timestamps, leading to mangled miss-sorted inboxes for customers. 3575 May 25 02:05 1306600913.M982997P26976.mail8.xxx.com:2,S 55313 May 6 01:50 1306600913.M982998P26976.mail8.xxx.com:2,S 9839 May 7 23:59 1306600913.M982999P26976.mail8.xxx.com:2,S 3453 May 10 01:32 1306600913.M983000P26976.mail8.xxx.com:2,S 16616 May 14 00:22 1306600913.M983001P26976.mail8.xxx.com:2,S 68850 May 25 00:46 1306600913.M983002P26976.mail8.xxx.com:2,S etc. Dovecot is v. 2.0.11 I guess I should have deleted all dovecot.* files after the restore, before I started dovecot? // Tom

[Dovecot] Custom sql query for keeping quota with dict-sql
by Marcin Mirosław 05 Jun '11

05 Jun '11

Hello! I'd like to setup quota for for virtualusers, i'm using both maildir++ and mdbox as storage, and i'm using postgresql to keep users. I'm keeping all users data in one table: [...] login text NOT NULL, domain text, password text, quota_mb integer NOT NULL DEFAULT 0 [... other columns ...] i'd like to keep present quota in such two columns: quota_dict_bytes integer NOT NULL DEFAULT 0, quota_dict_messages integer NOT NULL DEFAULT 0 I read wiki a little and it looks i can't define own sql queries, they appear to be hardcoded. Am i wrong? Is it possible to write own queries to get/set quota using such table schema? Or maybe there is diffrent way to track quota for diffrent storages? Regards! Marcin

[Dovecot] solr substring schema.xml
by Daniel Miller 03 Jun '11

03 Jun '11

I'm trying a modified schema.xml with solr - it appears I now have substring searches! I took the schema.xml file shipped with Dovecot, and modified the text field definition to be: <fieldType name="text" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.SnowballPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.NGramFilterFactory" minGramSize="3" maxGramSize="15"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.SnowballPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> </fieldType> Changing to the new "SnowballPorter" instead of the deprecated "EnglishPorter" filters is probably minor - the magic is the "NGramFilterFactory". 3 & 15 seemed reasonable defaults for the min/max size to search on. -- Daniel

[Dovecot] unexpected subfolder locaton in Maildir/.INBOX.subfolder

Hallo, I try to migrate existing imap server to dovecot 1.2 in debian squeeze if I connect to imap://user@host/INBOX Inbox works as expected and I get the content of Maildir/{cur,new,tmp} Maildir/.subfolder already exists if I connect to imap://user@host/INBOX.subfolder I get "folder not found" if I do a imap directory listing (raw mutt config, no subscriptions) - I see "../" - If I navigate to "../" I se all my existing subfolders if I create a new folder via imap the folder is created in Maildir/.INBOX.new_subfolder I expect the creation of Maildir/.new_subfolder This doesn't fit to the client configs and if I move the existing folders it doesn't fit to existing delivery agent filters and settings. I enabled mail_debug and the expansion looks ok for me: dovecot: imap-login: Login: user=<wulf>, method=PLAIN, rip=85.178.xx.xxx, lip=80.81.xxx.xxx, TLS dovecot: IMAP(wulf): Effective uid=112, gid=114, home=/var/mail/home/wulf dovecot: IMAP(wulf): maildir: data=~/Maildir dovecot: IMAP(wulf): maildir++: root=/var/mail/home/wulf/Maildir, index=, control=, inbox=/var/mail/home/wulf/Maildir the existing subscription information from courier-imap looks like INBOX.subolder Yes I can sed them to subfolder (of course I have to copy them to Maildir/subscriptions anyhow) But is that the idea?

[Dovecot] Running a dovecot cluster with mixed versions?
by Ian Foutch 03 Jun '11

03 Jun '11

I have been trying to find information and possible issues with running a cluster of dovecot server with different versions without any luck. We have an existing cluster with dovecot v1.1.10 and tried migrating to a new cluster with dovecot v2.0.12. We ran into some issues when we moved traffic to the new cluster and have been unable to reproduce it in our own testing. We may need to put real usage on the new servers but would like to be able to do this by adding newer servers into the existing cluster. What are the potential issues with doing this?

[Dovecot] Problems in auth when switching from PLAIN-MD5
by Eduardo Casarero 03 Jun '11

03 Jun '11

Hi, i am running dovecot 2.0.11 (with mysql backend) and until now using PLAIN-MD5 as pass default_pass_scheme everything was working fine. However i wanted to change the pass_scheme to something stronger than plain-md5, so i started by reading the wiki. I found this: http://wiki2.dovecot.org/HowTo/ConvertPasswordSchemes But when i comment out "default_pass_scheme" and i create the pass with the {SHA256.hex} prefix i see this in the logs: auth: Error: sql(xxx(a)xxxxxx.com,10.21.1.1): Password in passdb is not in expected scheme SHA256.hex I tried with several algorithms, but it seems to be something in my config that it's only working with plain-md5. the auth_mechanism is plain with ssl/tls. Maybe someone can give me a hint of where to see o which config file review. Thanks in advance. Eduardo.

[Dovecot] slow squat fts index creation
by Cor Bosman 03 Jun '11

03 Jun '11

Hi all, ive been playing with squat indexes. Up to about 300.000 emails in a single mailbox this was working flawlessly. The search index file is about 500MB at that time. Ive now added some more emails, and at 450.000 or so emails im seeing a serious problem with squat index creation. It takes...f o r e v e r . The .tmp file is being so slowly, it will probably take 2-3 hours to create. Upto this point it took maybe a minute. Im doing this in an openvz container, so theoretically i may be hitting some openvz resource limit. But ive upped all the limits and dont see any improvements. I dont see any resources starvation either. Could there be some dovecot issue when the search index reaches say 1GB? (im estimating that it's now trying to save about 1GB search index). Regards, Cor

[Dovecot] Dovecot 1.2 with MySQL limit Trash folder
by Damien Robinet 03 Jun '11

Hi All, I need your help to limit the size of the Trash folder. I want to exclude the Trash folder in my user quota. But I do not want the Trash folder can not exceed 10M for example. I can manage to exclude the size of the Trash folder. But I can not limit the size of the folder. On my test, I've bytes=512000 for the Trash folder. But the user can move more that 512000B on the Trash folder ... Could you help me please ?

[Dovecot] Error: file_dotlock_create failed: Permission denied
by M. Fioretti 03 Jun '11

03 Jun '11

Hi, I have a Fedora 14 x86_64 computer. I run dovecot 2.0.12 on it, only to keep a local imap copy of all my email, in maildir format. A couple days ago the hard disk broke, so I bought a new one, and reinstalled Fedora 14 x86_64 with all the updates. Then I copied all the maildirs from a backup to the new drive. But I can't access email now. No matter how I change sticky bits or ownership and permissions of all the involved files and directories, etc.. Login succeeds, but I get this error whenever I try to create new mailboxes or access existing ones: May 25 13:36:03 polaris dovecot: imap-login: Login: user=<marco>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=8489, secured May 25 13:36:06 polaris dovecot: imap(marco): Error: file_dotlock_open(/home/z/email/marco/dovecot.index.log) failed: Permission denied (euid=500(marco) egid=500(marco) missing +w perm: /home/z/email/marco, euid is not dir owner) May 25 13:36:06 polaris dovecot: imap(marco): Error: file_dotlock_create(/home/z/email/marco/dovecot-uidlist) failed: Permission denied (euid=500(marco) egid=500(marco) missing +w perm: /home/z/email/marco, euid is not dir owner) May 25 13:36:06 polaris dovecot: imap(marco): Error: file_dotlock_create(/home/z/email/marco/dovecot-uidlist) failed: Permission denied (euid=500(marco) egid=500(marco) missing +w perm: /home/z/email/marco, euid is not dir owner) May 25 13:36:06 polaris dovecot: imap(marco): Error: opendir(/home/z/email/marco/new) failed: Permission denied (euid=500(marco) egid=500(marco) missing +r perm: /home/z/email/marco/new, euid is not dir owner) May 25 13:36:06 polaris dovecot: imap(marco): Error: file_dotlock_create(/home/z/email/marco/dovecot-uidlist) failed: Permission denied (euid=500(marco) egid=500(marco) missing +w perm: /home/z/email/marco, euid is not dir owner) Again, this doesn't change changing ownership.

[Dovecot] Squat Question!
by Henrique Fernandes 03 Jun '11

03 Jun '11

Hello folks, I use dovecot squat for indexing. I use to have fts_squat = partial=4 full=4 But i change to fts_squat = partial=4 full=8 My question is, do i need to delete older indexes to have it consistenly, or dovecot is able "update" the indexes or it sees that it is broken and rebuild it all? Other question, is there an comand line to update the indexes ? Thanks a lot! []'sf.rique

[Dovecot] This is appear a fts bug
by Antonio Perez-Aranda 03 Jun '11

03 Jun '11

I have checked this on dovecot 2.0.9 and 2.0.13 with fts-solr without patching. If you execute the follow IMAP script, then the imap process die by and a "assert" . select "inbox." . search text something After search, the connection is aborted in the client side, and imap process died on the server. When the log in dovecot says: (fts_backend_solr_init): assertion failed: (*box_name != '\0') After debug the code, there isn't in context any possibility to get "box_name". With squat plugin it is running. -- 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] shared folders "invisible" on new setup
by Torsten Harenberg 03 Jun '11

03 Jun '11

Dear list, I hope this is not an old issue, but I couldn't find a solution even after google'ing quite some time. I try to migrate our institute's mail server (~200 users) from an old cyrus-based Mac installation to a new machine (NetBSD, dovecot 2.0.13). Everything went quite smoothly so far, but we are used to have "shared folders" ("public" folders in dovecot) and I simply couldn't make them to appear. I have two separate folders for private (user) mails and for public ones (yes, I set everything to 777 for the moment to avoid file access problems) : mailserver# pwd /var/mail mailserver# ls -al total 8 drwxrwxrwt 4 dovecot wheel 512 May 31 12:26 . drwxr-xr-x 28 root wheel 512 Mar 29 15:05 .. drwxrwxrwx 3 root mail 512 May 31 15:18 public drwxrwxrwx 4 root wheel 512 May 31 12:26 user In the public folder there is a shared folder named "fb8": mailserver# pwd /var/mail/public mailserver# ls -al total 8 drwxrwxrwx 3 root mail 512 May 31 15:18 . drwxrwxrwt 4 dovecot wheel 512 May 31 12:26 .. -rw-rw-rw- 1 10001 mail 0 May 31 15:14 dovecot-acl-list -rwxrwxrwx 1 root mail 0 May 31 11:06 dovecot-shared drwxrwxrwx 5 root mail 512 May 31 12:03 fb8 Now my own username (LDAP-based) is "harenber" and I try to subscribe myself to this list: mailserver# doveadm mailbox subscribe -u harenber public.fb8 mailserver# So a "subscriptions" file appears: mailserver# ls -al total 8 drwxrwxrwx 3 root mail 512 May 31 15:18 . drwxrwxrwt 4 dovecot wheel 512 May 31 12:26 .. -rw-rw-rw- 1 10001 mail 0 May 31 15:14 dovecot-acl-list -rwxrwxrwx 1 root mail 0 May 31 11:06 dovecot-shared drwxrwxrwx 5 root mail 512 May 31 12:03 fb8 -rw-rw-rw- 1 10001 mail 4 May 31 15:18 subscriptions mailserver# cat subscriptions fb8 mailserver# (although I think this is wrong, as I have namespace { list = children location = maildir:/var/mail/public:INDEX=~/public prefix = public. separator = . subscriptions = no type = public } I would assume this file to appear somewhere in /var/mail/user/harenber/public... ) But I cannot access this "fb8" folder with any client.

[Dovecot] Dovecot 2 + Director: IMAP+GSSAPI and LMTP-proxying
by Jahnke-Zumbusch, Dirk 03 Jun '11

03 Jun '11

Hi all, I have a setup of some nodes running Dovecot 2.0.13 and Postfix 2.5.6 with storage in NFS and authentication happening with PAM. Poking around in the wiki, I tried out different possibilities but now I am stuck -- and are hoping for your (enlightening) comments and tips. My planned setup for IMAP and LMTP is like this: IMAP ==== 1. A loadbalancer directs new sessions to a Dovecot-Director instance; this extra amount of traffic routing is mostly done for automatic handling in case of a failing Director node; this works fine, the same IP will end always on the same backend, but user-based Directory proxying seems more appropriate, especially taking the NFS-setup and the delivery process into account 2. Then the Director decides where to direct the user's session; this works fine when I let the backend servers do the authentication work 3. The backend Dovecot server will happily provide the user's e-mail For now my section for the passdb in the Director instance is passdb { driver = static args = proxy=y nopassword=y } So the backend will do the authentication of the session. But this setup inhibits using Kerberos, as the TGT is not forwarded to the backend server. I would very much like to provide GSSAPI/Kerberos authentication, which already works fine with the backend servers being directly connected by mail clients. The backend servers are using the PAM driver. I could not figure out, how to setup the passdb entry for the director instance to use PAM (this way enabling GSSAPI/Kerberos) and also giving back the necessary "proxy=y" to make director proxying the IMAP session. Is this setup feasible at all? LMTP ==== 1. Postfix accepts incoming e-mail and decides, which e-mail will go the LMTP-way to be deliverd into a Dovecot mailbox with something like virtual_transport = lmtp:inet:DOVECOT-DIRECTORS-IP:LMTP-PORT-ABC 2. the Dovecot Director instance accepts the LMTP connections and will proxy this to the appropriate==user's current backend server For now Postfix delivers e-mails using LMTP to the _backend_ w/o proxying and everything like SIEVE-filtering works fine: virtual_transport = lmtp:inet:DOVECOT-BACKENDS-IP:LMTP-PORT-XYZ But when I use the Director's IP/Port combination for LMTP, I see an error "554 5.4.6 <the(a)addr.ess> Proxying loops to itself". Where may I specify the port number of the backend server's LMTP-port? I suspect that the missing port number implies that the receiving LMTP-backend server uses the same port and so this would lead to a loop, hence the loop error?! I browsed the Wiki and the archives but still cannot find the information I am looking for. Any hints on that?

[Dovecot] doveadm "-S <socket_path>" option enabled in 2.0.8?
by David Warden 03 Jun '11

03 Jun '11

I apologize if this is a stupid question but I just compiled 2.0.8 and am trying to use doveadm to get the quota for a user using the -S <socket_path> option because I have different options for the various local IPs that dovecot listens on. For example, my default quota is filesystem (NFS rquota) and I can get that by doing: doveadm quota get -u warden which tells me: Quota name Type Value Limit % User quota STORAGE 1313476 1766400 74 But when I try to get my quota on a different local IP using the -S flag to doveadm: doveadm quota get -u warden -S 137.238.2.244:143 I am told: get: invalid option -- S The strange thing is doveadm's usage says that the -S option is valid for quite a few commands and in the man pages for those commands it looks like they should work for the way I'm calling doveadm. In the 2.0.8 source I also see code that looks like it should be parsing the -S flag. I can telnet to 127.0.0.1:143 and do ". getquotaroot inbox" which gives me the same information as "doveadm quota get -u warden" and I can telnet to 137.238.2.244:143 and ". getquotaroot inbox" also tells me my quota, but I'm hoping to use doveadm to periodically recalc my Maildir++ quota and update the squat FTS indexes and for that to happen doveadm needs to be able to be told what local IP address/port to connect to (I think).

[Dovecot] [dovecot] notifications when delivery fails
by Héctor Moreno Blanco 03 Jun '11

03 Jun '11

Hello Timo, We have dovecot 1.2.13. Is there any way to send notifications to the postmaster when a delivery fails? For example, when the dovecot index are corrupted and the mail is not sent to the user (the user who sent the message receives an error informing that the mail has not sent). Thank you very much in advanced.

[Dovecot] 2.0: deliver run from multiple uids and configuration files
by Arkadiusz Miskiewicz 03 Jun '11

03 Jun '11

I'm trying to run deliver from exim transport in a way that it doesn't need to query userdb AND doesn't need to read configuration files. The problem is that config files are readable for root only and if I run deliver with multiple UIDs then I would have to allow reading config files for everyone. Of course that's not a option because configs contain database passwords and such stuff. I wonder if it is possible to avoid reading config files by deliver? The only solution I see it to run deliver via sudo which doesn't look nice. -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] LMTP/Sieve/sendmail path
by Andreas Schulze 03 Jun '11

03 Jun '11

Hello, I have a system using postfix multi instance feature. The first, main postfix-instance is a nullclient as suggested by http://www.postfix.org/MULTI_INSTANCE_README.html#split The second instance is for real use. Postfix receive mail and handover them to the dovecot lmtp server. Thats working. The lmtp server supports sieve. One account has activated a vacation rule. So while delivering a mail to this account, dovecot creates a new mail based on the vacation rules. *This one* fail. It is injected in the main postfix instance, which is wrong in this case. I tried to start dovecot with an additional environment MAIL_CONFIG=/etc/postfix-instance2 and enabled alternate_config_directories in main.cf of the first insance. ( http://www.postfix.org/postconf.5.html#alternate_config_directories ) I also configured the userdb to return an extrafield userdb_mail_config=/etc/postfix-instance2. But all produce strance postfix errors I never saw in my last 6 years as postfix-admin. Would it be possible to configure dovecot lmtp server to use an external smtp-server to submit new mails ? Any other Ideas ?

[Dovecot] Baffled after upgrade
by Bert Todger 02 Jun '11

02 Jun '11

Hello all, I have just upgraded my Fedora 13 system to F15. With it came a shiny new dovecot 2.0.13 (Details of dovecot -n below). The configuration is different from the dovecot 1.something that I had been used to with F13, but I managed to get it working and all was well... Without changing anything related to dovecot (as far as I know), after a reboot, dovecot stopped working. I did a bit of digging, upped the verbosity of logging and found this in the logs: =======8<================================================================= Jun 02 09:58:21 auth: Debug: passwd-file /etc/passwd.dovecot: Read 3 users Jun 02 09:58:21 auth: Debug: auth client connected (pid=16699) Jun 02 09:58:21 auth: Debug: client in: AUTH 1 PLAIN service=imap secured lip=192.168.2.2 rip=192.168.2.2 lport=993 rport=33960 Jun 02 09:58:21 auth: Debug: client out: CONT 1 Jun 02 09:58:21 auth: Debug: client in: CONT 1 AG1hcmsAaWxIYWFkSFA= Jun 02 09:58:21 auth: Debug: Loading modules from directory: /usr/lib/dovecot/auth Jun 02 09:58:21 auth: Debug: Module loaded: /usr/lib/dovecot/auth/libauthdb_ldap.so Jun 02 09:58:21 auth: Debug: Module loaded: /usr/lib/dovecot/auth/libdriver_sqlite.so Jun 02 09:58:21 auth: Debug: Module loaded: /usr/lib/dovecot/auth/libmech_gssapi.so Jun 02 09:58:21 auth: Debug: passwd-file /etc/passwd.dovecot: Read 3 users Jun 02 09:58:21 auth: Debug: pam(mark,192.168.2.2): lookup service=dovecot Jun 02 09:58:21 auth: Debug: pam(mark,192.168.2.2): #1/1 style=1 msg=Password: Jun 02 09:58:23 auth: Info: pam(mark,192.168.2.2): pam_authenticate() failed: Authentication failure (password mismatch?)

I am puzzled by the reference to PAM authentication in the logs and in the dovecot -n output. Should I comment out all references to PAM? (in auth-system.conf.ext?) I and my family access mail through a variety of means, using Evolution on the home network, mobile devices (eg iPhone), webmail (using squirrelmail configured to access dovecot) and over ssh (using mutt). I don't necessarily want my (or their) email passwords to be the same as our PAM logon passwords (and at the moment they're not). So for me PLAIN has been the best solution up until now. What is my best (and simplest) solution?

[Dovecot] DOVECOT v2.0.11 using SIEVE not working

Hi, I'm trying to get sieve working with dovecot. I seem to have everything enabled but my scripts done seem to work. both sieve-filter (2000) and sieve (4190) are running along with pop3 and imap. I have a simple script which checks the email address and moves it to a folder. I'm at a loss as to what to check next. Thanks in advance, Matt

[Dovecot] Client IP log variable for proxy/director setups?
by Kelsey Cummings 01 Jun '11

01 Jun '11

Timo - it would be very convenient if we could get a variable that held the real client ip for use in logging with director/proxy setups. It's clearly already passed around in client->user->remote_ip but at this point, I don't see anyway to get it into the logs and it would take me ages to figure out the Right place to add it since client->user doesn't seem to be available in client-common.c: get_var_expand_table(..). Perhaps I'm missing something obvious? -- Kelsey Cummings - kgc(a)corp.sonic.net sonic.net, inc. System Architect 2260 Apollo Way 707.522.1000 Santa Rosa, CA 95407

[Dovecot] PAM config problem...

Hi, I had some troubles with PAM configuration. I need to restrict imap access to some users (and allow pop3 to all).

Is there a known workaround for users who want to use the old recipient delimiter plus sign method of sorting their mail? eg: foo.bat +dovecot(a)example.com <foe.blow%2Bdovecot(a)example.com> This does not work with postfix/dovecot, but if we tell postfix/system-passwd to use the recipient_delimiter = + it works just like I recall sendmail did, but we no longer use local users only virtual dovecot LDA w/mysql. postfix appears to accept it testing by telnet, but then the message gets a new DSN generated saying no user, so dovecot LDA must not work by default with this.

[Dovecot] Email being stored in "cur" folder and not being downloaded in Thunderbird
by Jay Welch 27 May '11

27 May '11

Hi, I have recently noticed that a random number of emails are being stored in the "cur" folder under certain users and cannot be downloaded in Thunderbird. I have tried moving the emails from "cur" to "new" but everytime I try to download the email from Thunderbird, the emails go back to the "cur" folder. What could be causing this? What is the "cur" folder used for? I had thought that the "cur" folder was used for IMAP but all the users here are using POP. Also, I have tried testing this on Outlook and Outlook seems to download the files from "cur". Thanks

Is there any specific optimization/tunning on dovecot for use GFS2 on rhel6??, we have configured the director to make the user mailbox persistent in a node, we will thank's any help from you. we are interested in using GFS2 or NFS, we believe the problem is the locks, how can we improve this?? best regards, Aliet The results rhel 4.8 x86_64/GFS1 two nodes, shared FC lun on a SAN Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 1- 2608 1321 1311 2608 2508 3545 547 2001 2493 2702 5282 2- 2810 1440 1430 2810 2688 3835 403 2154 2679 2925 5706 3- 2913 1457 1441 2908 2778 3913 417 2253 2773 3034 5924 4- 2814 1448 1412 2812 2695 3910 401 2186 2686 2929 5712 5- 2789 1464 1432 2787 2652 3774 427 2112 2649 2879 5676 6- 2843 1460 1444 2839 2722 3948 422 2164 2713 2957 5778 rhel6 x86_64/GFS2 two nodes, shared FC lun on a SAN(Used RDM in VMWare vSphere for GFS2 lun) Tunned cluster suite cluster.conf + <dlm plock_ownership="1" plock_rate_limit="0"/> <gfs_controld plock_rate_limit="0"/> Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 1- 2730 1340 1356 2704 2644 3748 522 2125 2643 2662 5422 2- 3309 1618 1659 3294 3223 4658 531 2563 3221 3239 6596 3- 2131 1046 1017 2055 2025 2911 381 1608 2024 2052 4256 4- 2176 1055 1039 2082 2058 2947 377 1671 2058 2078 4344 5- 1859 928 931 1859 1800 2626 304 1454 1799 1801 3706 6- 2672 1322 1329 2672 2607 3758 464 2097 2606 2615 5326 rhel6 x86_64/GFS2 two nodes, shared FC lun on a SAN(Used RDM in VMWare vSphere for GFS2 lun) Cluster suite defaults configs for plocks Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 1- 1417 644 676 1325 1305 1872 308 1048 1302 1318 2824 2- 837 378 392 742 726 1050 117 588 722 734 1658 3- 803 363 347 752 745 1069 153 597 744 750 1658 4- 1682 802 811 1587 1569 2261 291 1299 1569 1585 3360 5- 1146 583 564 1146 1037 1500 213 811 1037 1049 2290 6- 838 403 366 744 734 1057 152 561 731 736 1664 rhel6 x86_64 two nodes used NFS(NAS Freenas 0.8, nfsvers 3) Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 1- 1382 699 691 1357 1063 1500 224 861 1053 1313 2694 2- 1634 785 799 1610 1459 2120 311 1192 1451 1570 3204 2- 1635 826 806 1611 1463 2088 345 1159 1459 1568 3190 3- 1574 758 781 1537 1403 2060 324 1135 1396 1504 3090 4- 1685 842 807 1653 1506 2135 349 1215 1504 1634 3344 5- 1766 850 893 1737 1582 2289 335 1288 1579 1705 3480 6- 1597 797 769 1572 1423 2007 313 1133 1420 1536 3142 rhel6 x86_64 local storage Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 1- 7798 3868 3889 7706 7566 10713 1080 6089 7559 7688 15562 2- 7806 3879 3874 7716 7585 10873 1114 6018 7578 7696 15572 3- 7866 3910 3855 7773 7748 11053 1076 6253 7747 7761 15710 4- 7893 3978 3931 7802 7772 10988 1117 6197 7767 7789 15760 5- 7775 3853 3809 7683 7654 10897 1081 6142 7651 7675 15534 6- 7877 3919 3872 7789 7758 10986 1085 6218 7755 7773 15720

[Dovecot] Moving maildir mailboxes
by Willie Gillespie 26 May '11

26 May '11

I am using Maildir with Dovecot 1.2. (Config available if needed, but should be a simple question.) I have a bunch of mail that I would like to do a one-time move from a private namespace to a shared namespace. The namespaces are already set up, etc. Can I just move the folders to their new location? I am not merging with existing folders, they would be new subfolders. Thanks! - Willie

[Dovecot] 2.0.12 (fa2e92526716): Deleting mails and folders from public namespaces
by Binarus 26 May '11

26 May '11

Hello, we basically run a dovecot imap setup where users' mailboxes are in private namespaces (as usual), but there is a public namespace with several thousand deeply nested folders also. The client we use is Thunderbird 3. The public namespace shows up in each user's account at the top level (i.e. same level as Inbox, Sent and so on), and users can make new subfolders in the public namespace, copy mails to it and so on. So, our setup basically works. But whenever a user tries to delete a folder from the public namespace, dovecot gives the following error: "Renaming not supported across non-private namespaces". I think I have a grasp why this happens (Thunderbird tries to move the folder from the public namespace into the trash folder (private namespace) of the user who does the deletion), and I also have read Timo's statement that he does not plan to support such renaming due to big problems he is seeing with it. Nevertheless, since deleting a folder from a public archive is not a too uncommon thing, I wanted to ask how other people have solved that. It came to my mind to configure Thunderbird to immediately delete folders and messages (instead of moving them to trash folder). I have tested that, and it worked, but is somehow dangerous and unsatisfying. Furthermore, I haven't completely understood the reason for the different behaviour of folders in the public namespace and a single message therein. If I configure Thunderbird to use the trash folder, users can delete messages from the public namespace, i.e. Thunderbird can move messages from the public namespace to the private trash folder of the respective account. This is obviously not true for folders (even if they are empty). What's the difference between an empty folder and a single message in this respect? Is it really the ACL thing which makes folders so difficult to handle opposed to single messages? Thank you very much for any ideas!

[Dovecot] v1.1.20 vs v1.2 & v2.0
by Adam 25 May '11

25 May '11

I am currently running v1.1.20 and was wondering if there is any compelling reason to upgrade to v1.2 or v2.0? For example is there any security updates in v1.2 or v2.0 that aren't included in v1.1.20? The other major thing I would be interested in knowing is there any speed enhancements in the newer versions? I am using basic PAM Auth and Maildir mailboxes on a Linux box. Let me know if you need any more information to answer my questions. Thanks, Adam

[Dovecot] problems with debian 5.0 and thunderbird
by Steven Jones 25 May '11

25 May '11

Hi, Does anyone have a setup guide for Thunderbird and Dovecot on Debian please? Dovecot is 1.0.15 I have Dovecot running listening on 143 and I can telnet from the XP guest but Thunderbird cant or wont talk to it. I have taken the # off listen and I get a telnet reply, no firewall is configured.... Ive set thunderbird up lots so I suspect its not Thunderbird but a dovecot config I have wrong. regards

[Dovecot] libwrap does it work on in 2.0?
by a.smith＠ukgrid.net 24 May '11

24 May '11

Hi, I noticed recently that libwrap (TCP Wrappers) is supported, although disabled by default, in the current Dovecot 2.0 but doesn't seem to be mentioned anywhere on the wiki. Is this working well/at all? Anyone care with experience using this care to share their experiences? My OS is FreeBSD, I noticed on some Linux distributions there may be issues, but this won't affect my installation. thanks Andy.

I'm all for that since I don't seem to have any need for a home directory. Any idea of how to do it with a passwd-file userdb backend? I also tried to override home directory with userdb { driver = passwd-file args = /etc/passwd home=/bundled/home/$n } but that didn't work out too well.

[Dovecot] delegation of admin rights
by Ariel Biener 23 May '11

23 May '11

Hello, We're a rather largish university (largest in Israel), with some 60-70k users, using Dovecot 1.2.14 (we're cautious about moving to 2.0.x for now). We need to provide admin rights to faculty computer/IT staff, so they can have access to the mailboxes of their respective users. We use LDAP as an authentication/authorization backend. Currently, dovecot has a "master user" which can access all mailboxes. I am looking for a solution, preferably within dovecot, to create a delegation type of administration, allowing certain users to access the mailboxes of other users based on an LDAP filter or LDAP attribute value. If possible, allowing per protocol access(that is, I would like to give them IMAP access and not POP3) and within IMAP allowing only to view a mailbox, but not to change it, that would be even better. Does anyone on this list know of any IMAP proxy providing such abilities, and also, would the Dovecot team consider this as a candidate for a request for enhancement ? This would be very useful in a delegated administration environment, like most larger organizations, hosting & ISP, and other environments where delegation is an important and very much needed ability. thanks a bunch, -- Ariel -- Ariel Biener e-mail: ariel(a)post.tau.ac.il PGP: http://www.tau.ac.il/~ariel/pgp.html

I'm considering to move my mails from maildir/mbox to mdbox. One of my doubts is: how can I restore my mails when something terrribly wrong happens. I understand that I should use doveadm import "backup_location" "mailbox" all. So I try to import with: doveadm -v import "sdbox:~/Mail/dbox-temp/spamcop/reports/" "#Dbox/spamcop/reports" all #Dbox namespace were defined as: --8<---------------cut here---------------start------------->8--- namespace { hidden = no inbox = no list = yes location = mdbox:~/Mail/Dbox prefix = "#Dbox/" separator = / subscriptions = yes type = private } --8<---------------cut here---------------end--------------->8--- dbox-temp were defined earlier as --8<---------------cut here---------------start------------->8--- namespace { hidden = no inbox = no list = yes location = sdbox:~/Mail/dbox-temp separator = / subscriptions = yes type = private } --8<---------------cut here---------------end--------------->8--- 1. when I specified for example sdbox:~/Mail/dbox-temp/spamcop/reports/ doveadm search mails under ~/Mail/dbox-temp/spamcop/reports/mailboxes/INBOX/dbox-Mails/ - am I missing something from documentation? (I expected rather ~/Mail/dbox-temp/mailboxes/spamcop/reports/dbox-Mails) 2. when I move dbox-Mails to proper place I got: doveadm(kjonca): Error: sdbox /home/kjonca/Mail/dbox-temp/spamcop/reports/mailboxes/INBOX/dbox-Mails: Invalid dbox header size doveadm(kjonca): Error: sdbox /home/kjonca/Mail/dbox-temp/spamcop/reports/mailboxes/INBOX/dbox-Mails: Invalid dbox header size And nothing were imported. Notices: a) there were only u.* files, no indexes. b) u.* files were created on i386 system, and import test on amd64. KJ -- http://blogdebart.pl/2010/03/17/dalsze-przygody-swinki-w-new-jersey/
