[Dovecot] dovecot not delivering emails in the right folder
by paulino＠calderonpale.com 10 Feb '11

Hello everyone, I'm having trouble getting postfix + dovecot to work correctly. It seems like Postfix is receiving and delivering the emails correctly but dovecot is placing/looking for them in the wrong folder therefore the clients aren't receiving any new emails. I switched from courier and followed a tutorial found here: http://library.linode.com/email/postfix/dovecot-mysql-debian-5-lenny Dovecot's log: deliver(adomain.com/test/@adomain.com): 2011-02-04 21:48:04 Info: Module loaded: /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so deliver(adomain.com/test/@adomain.com): 2011-02-04 21:48:04 Info: auth input: adomain.com/test/@adomain.com deliver(adomain.com/test/@adomain.com): 2011-02-04 21:48:04 Info: auth input: uid=5000 deliver(adomain.com/test/@adomain.com): 2011-02-04 21:48:04 Info: auth input: gid=5000 deliver(adomain.com/test/@adomain.com): 2011-02-04 21:48:04 Info: auth input: home=/home/vmail/adomain.com/adomain.com/test/ deliver(adomain.com/test/@adomain.com): 2011-02-04 21:48:04 Info: maildir: data=/home/vmail/adomain.com/adomain.com/test/ deliver(adomain.com/test/@adomain.com): 2011-02-04 21:48:04 Info: maildir: root=/home/vmail/adomain.com/adomain.com/test, index=/home/vmail/adomain.com/adomain.com/test, control=, inbox= deliver(adomain.com/test/@adomain.com): 2011-02-04 21:48:04 Info: cmusieve: Using sieve path: /home/vmail/globalsieverc deliver(adomain.com/test/@adomain.com): 2011-02-04 21:48:04 Info: cmusieve: Executing script /home/vmail/globalsievercc deliver(adomain.com/test/@adomain.com): 2011-02-04 21:48:04 Info: msgid=<AANLkTimZi7pD2eSFNipHtmS5HZVstk9UF6kjWEyqynz-(a)mail.gmail.com>: saved mail to INBOX It seems like is using a wrong folder value since it should be using /home/vmail/adomain.com/test. Another odd thing is that postfix is replacing the email address with /folder/user(a)adomain.com.

[Dovecot] pop3 index virtual question
by Robert Schetterer 10 Feb '11

10 Feb '11

Hi @ll, Timo, on 2.0.9 i have a user reporting pop3 leaving mails on the server does not work as desired i have namespace default { # type = private separator = / prefix = "" list = yes # hidden = no subscriptions = yes } namespace virtual { # type = private prefix = "virtual/" separator = / location = virtual:/etc/dovecot/virtual:LAYOUT=maildir++ #location = virtual:/etc/dovecot/virtual hidden = yes list = no subscriptions= no } namespace real { # type = private prefix = "RealMails/" separator = / list = no hidden = yes } and pop3_uidl_format = %08Xu%08Xv before it was pop3_uidl_format = %g ( not sure what best ) # Permanently save UIDLs sent to POP3 clients, so pop3_uidl_format changes # won't change those UIDLs. Currently this works only with Maildir. #pop3_save_uidl = no my guess is that location = virtual:/etc/dovecot/virtual:LAYOUT=maildir++ isnt enough should be location = virtual:/etc/dovecot/virtual:LAYOUT=maildir++:INDEX=~/ to store/use indexes in the local maildir which is physical under /usr/local/virtual/domain/user@domain any meanings to this -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] Using -s in "doveadm mailbox create"
by Christoph Pleger 10 Feb '11

10 Feb '11

Hello, it seems that "doveadm mailbox create" does not handle the mailbox parameters correctly if used with the "-s"-Parameter. I am using the following command in a script for adding new users: doveadm mailbox create -u "${ACCOUNT}" -s INBOX Drafts Sent Trash Spam Templates This creates mailboxes Drafts, Sent, Trash, Spam and Templates, but not INBOX. Likewise, when I omit INBOX in the command, only Sent, Trash, Spam and Templates are created, but not Drafts. With only one mailbox parameter, I get an error message about incorrect usage. When I enter the command without the "-s"-Parameter, all given mailboxes are created. As a workaround, I have to use the command without "-s" first and then call "doveadm mailbox subscribe". Regards Christoph

[Dovecot] Force STARTTLS on port 143 for !internalnetwork
by Ralf Hildebrandt 09 Feb '11

09 Feb '11

Hi! How can I force users which are connecting from OUTSIDE our newtworks to user STARTTLS on Port 143? Right now we resort to IMAPS on port 993, but an additional STARTTLS enabled login on the default port would make things easier! -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] Dovecot + Solr does not index without break-imap-search?
by Jose Álvaro Domínguez Díaz 09 Feb '11

09 Feb '11

Hi folks, We are working with Dovecot 2.0.9 with Solr support and there is a thing, a little strange for us. Let me explain. We have this conf for Solr: plugin { ... fts = solr fts_solr = url=http:// solr.domain:8983/solr/ break-imap-search quota = maildir ... } With 'break-imap-search', Dovecot connects with solr, solr indexes all, searchs are fast and all works fine. BUT if we don't add 'break-imap-search', solr doesn't index anything. Logs don't report errors with debug/verbose options enabled. Somebody has any idea about this?. Thank you very much for all. Regards. -- Jose Álvaro Domínguez adominguez(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] Permissions in shared folders
by Lukas Haase 09 Feb '11

09 Feb '11

Hi, On my mail server I want to implement shared folders for each workgroup where there are many workgroups. One way would be to create a separate namespace for each workgroup. However, this does not scale well so I decided to use a single Shared mailbox and use ACLs: namespace public { separator = . prefix = Shared. location = maildir:/var/mail/shared:CONTROL=~/Maildir/shared } Each workgroup should get a subfolder in "Shared". Until now, this works, I create .Group1, .Group2 and assign correct group permissions and ACL files. However, now a user from group1 wants to create a subfolder in his IMAP folder. Since the permissions for /var/mail/shared/.Group1 are correct (writeable to group1 and the user is member of group1 and 'k' ACL permissions are active) I would expect it to work. However, for obvious reasons, the *sub*folder is created as /var/mail/shared/.Group1.Subfolder so it is actually not a subfolder in sense of the filesystem but rather a folder inside /var/mail/shared However, the user does (and should) not have write permissions to /var/mail/shared (only to /var/mail/shared/.Group1). Is there a way to overcome this problem? Why can't dovecot just use /var/mail/shared/.Group1/.Subfolder? Is there an option to do so? It would make everything a lot easier. The one option is to make /var/mail/shared world-writeable - which is not really a good option. A second option might be to use ACLs and give each group write permissions to /var/mail/shared. However, not even this seems very "clean" to me. What is the best way to handle this? Best regards, Luke

[Dovecot] ldap: LDAP attribute used multiple times. This is currently unsupported
by Lukas Haase 09 Feb '11

09 Feb '11

Hi, I have a problem when migrating from dovecot 1.0 to dovecot 1.2 (Debian lenny to Debian squeeze). In my dovecot-ldap.conf I have: user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,uid=system_groups_user I use the last parameter for the groups which I need for shared folders. If I only use this, everything works. However, I also use LDAP as passdb with prefetch: pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid,uid=userdb_system_groups_user In this configuration I get the error in the subject line that uid is used multiple times. I know, but the message is somehow "weird" since it says it is *currently* unsupported. However, it seems to me that it is not supported any more. Is this true? Is there a reason for this? How can I fix this problem? Until now my shared folders do not works anymore because the group memberships are not assigned any more because of the missing system_groups_user parameter. Best regards, Luke

[Dovecot] Great time savings backing a mdbox versus Maildir
by Javier Miguel Rodríguez 09 Feb '11

09 Feb '11

Hello I am writing to this mailing list to thanks Timo for dovecot 2 & mdbox. We have almost 30.000 active users and our life was sad with Maildir & backup: 24 hours for a full backup with bacula (zlib enabled maildirs, 1.4 TB). After switching to mdbox, the backup time is under 12 hours ! Instead of backing 17 millions files, with mdbox our backup is only of 1 million files, and that speeds up a lot the backup operation. Timo, here you have detailed info about the bacula backup jobs, you can use them in the wiki if you desire. If you need aditional info (hardware specs, dovecot config, etc) I can share it. *Maildir:* |//Job: Backup_Linux_buzon_us.2011-01-21_19.03.26_38 Backup Level: Full Client: "buzon_us" 2.0.3 (06Mar07) x86_64-redhat-linux-gnu,redhat,Enterprise release FileSet: "Full Buzon" 2011-01-21 19:03:26 Pool: "Pool_Linux_Buzones_US" (From Job resource) Catalog: "MyCatalog" (From Client resource) Storage: "File" (From command line) Scheduled time: 21-ene-2011 19:03:20 Start time: 21-ene-2011 19:03:29 End time: 22-ene-2011 19:46:45 Elapsed time:*1 day 43 mins 16 secs* Priority: 10 FD Files Written: 16,903,801 SD Files Written:*16,903,801* FD Bytes Written: 1,445,943,227,706 (1.445 TB) SD Bytes Written: 1,448,983,971,450 (1.448 TB) Rate:*16247.3 KB/s* Software Compression: None VSS: no Encryption: no Accurate: no Volume name(s): Buzones_US_2 Volume Session Id: 26 Volume Session Time: 1295511704 Last Volume Bytes: 1,450,628,892,676 (*1.450 TB*) Non-fatal FD errors: 0 SD Errors: 0 FD termination status: OK SD termination status: OK Termination: Backup OK//| *mdbox with mdbox_rotate_size=10m:* |Build OS: x86_64-redhat-linux-gnu redhat Enterprise release JobId: 3587 Job: Backup_Linux_buzon_us.2011-02-07_08.13.52_53 Backup Level: Full (upgraded from Incremental) Client: "buzon_us" 2.0.3 (06Mar07) x86_64-redhat-linux-gnu,redhat,Enterprise release FileSet: "Full Buzon" 2011-01-21 19:03:26 Pool: "Pool_Linux_Buzones_US" (From Job resource) Catalog: "MyCatalog" (From Client resource) Storage: "File" (From command line) Scheduled time: 07-feb-2011 08:13:44 Start time: 07-feb-2011 08:13:54 End time: 07-feb-2011 19:43:50 Elapsed time:*11 hours 29 mins 56 secs* Priority: 10 FD Files Written:*1,148,780* SD Files Written: 1,148,780 FD Bytes Written:*1,537,062,152,773 (1.537 TB)* SD Bytes Written: 1,537,218,147,402 (1.537 TB) Rate:*37130.7 KB/s* Software Compression: None VSS: no Encryption: no Accurate: yes Volume name(s): Buzones_US_4|Buzones_US_5 Volume Session Id: 101 Volume Session Time: 1296724657 Last Volume Bytes: 438,873,898,586 (438.8 GB) Non-fatal FD errors: 0 SD Errors: 0 FD termination status: OK SD termination status: OK Termination: Backup OK| Regards Javier de Miguel University of Seville
