[Dovecot] Why does dovecot require the {} password sheme even if there is a $ crypt scheme.
by da-dovecotlist-15＠abelonline.de 15 Jan '14

The wiki[1] says: If all the passwords are in same format, you can use default_pass_scheme to specify it. Otherwise each password needs to be prefixed with "{password-scheme}", for example "{plain}plaintext-password". Why doesn't dovecot recognize the crypt scheme identifier ($1$ for MD5-CRYPT, $6$ for SHA512-CRYPT etc.)? At the moment I have to have the following in my db for dovecot to work: {SHA512-CRYPT}$6$salt$passwordhash [1]http://wiki2.dovecot.org/AuthDatabase/SQL

[Dovecot] dsync mbox to maildir migration does not delete, deleted e-mails
by A M 15 Jan '14

15 Jan '14

Hello, I am planning to migrate all users from mbox to maildir. I am trying to do it with minimum downtime. (~100GB data) All users are currently using POP3. Dovecot version is 2.2.10 (latest). Command used is: dsync -u username mirror maildir:~/Maildir Process I plan is: (omitting steps related to sendmail / procmail) 1) keep dovecot running (with mail_location as mbox) 2) dsync for all users (this may take 3-4 hours or more) 3) (downtime starts) stop dovecot and sendmail (to stop new e-mails) 4) block pop3, imap ports on firewall (so users can not connect) 5) start dovecot (still with mbox) 6) dsync again to sync e-mails arrived between step 2 and 3 7) dsync again (just to make sure!) 8) (downtime ends) restart dovecot (with mail_location as maildir) Now, here is my problem. Lets say there is user joe, who has 50 NEW e-mails in mbox (INBOX). Step 2 perfectly syncs his 50 e-mails to 'new' folder of maildir. Now in the mean time, before step 3, he connected via POP3 and downloaded and deleted 50 e-mails. Now when we reach step 6 (re-sync), what I expected was dsync will detect that 50 e-mails are deleted and it will delete 50 e-mails from 'new' directory of maildir. But that is not happening. 50 e-mails are still there. I fear that these e-mails will be re-downloaded on his Outlook once I switch dovecot to maildir. This will happen for each and every user which will cause huge mess. So how to tell, dsync to delete non-existent e-mails which are no more there in mbox (INBOX)? Thanks in advance, Regards, A M

[Dovecot] Dovecot service not responding after about a week of uptime
by Matthieu 15 Jan '14

15 Jan '14

Hello, I am running a dovecot 2.1.13 server and lately it stops responding after about a week of uptime. Simply restarting the dovecot service solves the issue. I tried to look a bit in my maillog file but did not find anything obvious. During the time when the server is not responding I can still see imap-login entries from the connection attempt by my email client. Any help about how to diagnose the problem would be appreciated. Thanks, Matthieu

[Dovecot] Dovecot LMTP does not pass envelope recipient +detail to sieve
by Greg Rivers 14 Jan '14

14 Jan '14

I found this[1] thread that describes the same problem with dovecot-LDA, but the solution (add X-Original-To: header) has no effect with LMTP. My sendmail LMTP configuration: FEATURE(`local_lmtp',`[IPC]',`FILE /var/run/dovecot/lmtp') Sendmail's address test indicates that sendmail is providing user+detail to LMTP (see below). Except for this problem, dovecot, LMTP, and sieve are all working perfectly. Is there something I'm missing, or is this a bug?

[Dovecot] Sieve - not functioning for additional email aliases.
by Jacek Osiecki 14 Jan '14

14 Jan '14

Hi, On one of my servers (old one, version 1.2.5) user reported that vacation message for basic address works fine, but not for the aliases. I know that this is an old version, but we can't simply switch them to the most current dovecot release without preparing and testing everything... So I'm rather asking for help with debugging the case :) This person has email my.name(a)olddomain.pl. However, they are switching to new domain - newdomain.pl - and it is becoming their main brand. So temporarily olddomain.pl is still their "home" domain, but there is a domain alias newdomain->olddomain. The sieve file is simple: forward message and reply with vacation: ---- require ["copy","vacation"]; # rule:[redirect] if anyof (true) { redirect :copy "my.boss(a)newdomain.pl"; vacation :days 1 :addresses ["my.name(a)olddomain.pl","my.name(a)newdomain.pl"] text: I'm unavailable now. Please contact my boss: my.boss(a)newdomain.pl Greetings . ; } ---- When I send email to my.name(a)olddomain.pl - it is sent to my.boss(a)newdomain.pl and I receive the vacation message. When I send it to the alias (my.name(a)newdomain.pl) - none of above is done. Any idea how I can debug it? Running test-sieve does not help - it claims that will simply forward and deliver the message... Greetings, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need. I want something I want.

[Dovecot] dict ldap
by me＠electronico.nc 14 Jan '14

14 Jan '14

Hello everybody, Dovecot 2.2.6 with LDAP auth against AD (Samba4). I would like to know if it's possible to specify an LDAP transport for dict (something like dovecot-dict-ldap.conf.ext). I'm in need to setup shared mailboxes and if I could query LDAP, that would help a lot. IE : user1 user2 user3 are in OU=group1, so group1 (setup as user in AD) would share its mailbox with user1 user2 and user3. Thanks in advance for your time. Nicolas
