[Dovecot] Reading Mutt mboxes from Thunderbird
by Leonardo M. Ramé 25 Apr '12

25 Apr '12

Hi, I'm a user of Mutt, and before moving to Thunderbird I'm trying to share mboxes between them. To do this, I installed Dovecot to create an IMAP server in my local machine, to serve mutt mboxes to be read by Thunderbird. So far, I can read my inbox from /var/mail/%u, but in mutt, I have many folders in ~/mail, like 2010-mails, 2011-mails, mailing-list-x, mailing-list-y, and so on. How can I configure Dovecot to read them?. In /etc/dovecot/conf.d/10-mail.conf I have this: mail_location = mbox:~/Mail:INBOX=/var/mail/%u I'm using Ubuntu 11.10, and Dovecot 2.0.13.

[Dovecot] How to remove duplicate GUID messages from storage?
by Daniel Parthey 25 Apr '12

25 Apr '12

Hi, I tried to import messages like this: doveadm import -u username(a)example.org mdbox:/mail/dovecot/example.org/username/mail mbox:/root/mail.txt all This seemed to have imported the same messages in the mail storage, as they were already there. And now I have got a lot of duplicates. Then I deleted the mbox:/root/mail mail stuff from "mailboxes" folder and the storage remained, with duplicate GUIDs. The following command doveadm -v force-resync -u username(a)example.org INBOX outputs lots of messages like this one, with different GUID doveadm(username(a)example.org): Error: mdbox /mail/dovecot/example.org/username/mail/storage: Duplicate GUID 0b8a032d66a0924fb42c0000de5f8128 in m.55:45484041 and m.14:52173045 The messages at m.55:45484041 and m.14:52173045 have the same content, since they were seemingly imported from the mail store itself, they are in the storage twice now and require twice as much disk space as before. How can I manually remove these identical, duplicate messages from the storage to save space? Dovecot does not do it automatically. Kind regards, Daniel

[Dovecot] 2.1.5 problem with mail_location
by postmaster 25 Apr '12

25 Apr '12

I've been advised to set : mail_location = maildir:~/ as the home directory is found through a sql request. this has been working perfectly up to and including 2.1.4 from 2.1.5 however this setting gives cause to a problem : instead of looking in the mail home eg /var/mail/domain/user\@domain/ dovecot is looking for mail in /var/mail/domain/user\@domain/~ the '~' directory is created upon the first request for mail and all future mail transactions in dovecot is done relative to this folder. is this behavior a bug or a feature ??? -- Bjarne D Mathiesen København N ; Danmark ; Europa ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ denne besked er skrevet i et totalt M$-frit miljø MacOS X 10.7.3 Lion ; 2.8GHz Intel Core i7 ; 16GB 1067MHz DDR3

[Dovecot] dsync on large mailbox "fails"
by Jeff Kletsky 25 Apr '12

25 Apr '12

I've been trying to convert an existing set of mbox mail to maildir using dsync, but it seems to fail when it gets to the large boxes. $ dsync -Dv mirror maildir:~/Maildir Everything seems to work reasonably well until the first of the large boxes hits: dsync(jeff): Warning: Maildir /home/jeff/Maildir/.cron.2010-07-10: Synchronization took 1210 seconds (102289 new msgs, 0 flag change attempts, 0 expunge attempts) dsync(jeff): Warning: Transaction log file /home/jeff/Maildir/.cron.2010-07-10/dovecot.index.log was locked for 1210 seconds After this, the doveadm process goes from ~75% of the CPU core utilization to 100% and stays there, even overnight. I've also tried $ dsync -Dv backup maildir:~/Maildir with similar results. While I did see some threads on dsync speed, they seemed to be minutes for a few GB of data, not hours. There is plenty of space on the drive, and, from what I understand, there is not a file-count limit on FreeBSD's ufs (at least not one that I'm anywhere near) Any suggestions? Thanks!

[Dovecot] trash plugin bug?
by Cor Bosman 25 Apr '12

25 Apr '12

Hey all, has anyone ever tried turning on the trash plugin when the directory is already over quota? I see some messages being deleted, but it seems it just deletes enough to fit the new email, not enough to go below quota. Example: . getquotaroot "Spam" * QUOTAROOT "Spam" "User quota" "Spam Quota" * QUOTA "User quota" (STORAGE 591036 5242880) * QUOTA "Spam Quota" (STORAGE 21173 20480) I now move a 5K message into this folder, and I see: Apr 23 22:26:43 lmtp1 dovecot: imap(cor): expunge: box=Spam, uid=226337, msgid=<3YVKIIE4II6R0064BA7IM55C2Q4MD01VX12U1I(a)shedevils.com>, size=12984 Apr 23 22:26:43 lmtp1 dovecot: imap(cor): expunge: box=Spam, uid=226338, msgid=<aab6bffa3ad83767d4a7bc571c31449c(a)bonus-news.com>, size=5623 Apr 23 22:26:43 lmtp1 dovecot: imap(cor): save: box=Spam, uid=227759, msgid=<20120423191509.F3B584A355B(a)signal.groundspeak.com>, size=2694 And now: . getquotaroot "Spam" * QUOTAROOT "Spam" "User quota" "Spam Quota" * QUOTA "User quota" (STORAGE 591016 5242880) * QUOTA "Spam Quota" (STORAGE 21158 20480) . OK Getquotaroot completed. This seems like a possible bug. For one, it shouldnt be allowed to actually save a message into that folder, but it does. The email does end up in the Spam folder even though the folder is over quota. And of course it doesnt clear up enough space to have the new email fit, it just deleted enough to match the 5K. Without the trash plugin quota is being properly enforced. Everything works fine if you start out below the quota limit btw. Regards, Cor ps: this is 2.1.4, but with the recent trash and quota patches applied.

[Dovecot] Dovecot Virtual Users with Users Domain Mapping
by Piotr Maier 24 Apr '12

24 Apr '12

I have successfully compiled, configured and ran Dovecot with virtual users feature. Here's part of my /etc/dovecot.conf configuration file: mail_location = maildir:~/Maildir auth default { mechanisms = plain login userdb passwd-file { args = /home/%d/etc/passwd } passdb passwd-file { args = /home/%d/etc/shadow } socket listen { master { path = /var/run/dovecot/auth-worker mode = 0600 } } } I faced one issue I can't resolve myself. Is there anyway to create users' domains mapping and provide username in mail_location? Example of usersdomains file: domain.com:user1 domain2.org:user3 Examples: 1. currently I have /home/domain.com/user/Maildir 2. I'd like to have /home/SYSTEM_USER/domain.com/user/Maildir Can I achieve this somehow?
