[Dovecot] Specifying passwd-file with virtual domains?
by Jeffrey Walton 01 Apr '14

01 Apr '14

I'm trying to use virtual domains and I'm suffering a disconnect. I have two domains - foo.com and bar.com. On the filesystem, they are located at /var/mail/foo.com/ and /var/mail/bar.com/. Users are located at /var/mail/foo.com/john/, /var/mail/bar.com/jane/, etc. There are two password files with <user>:<scheme><password> entries. The scheme is {PLAIN}. They are located at /var/mail/foo.com/users and /var/mail/bar.com/users. According to the wiki, these are passwd-file databases (http://wiki2.dovecot.org/AuthDatabase/PasswdFile) I specified the following in my dovecot.conf. passdb { args = /var/mail/%d/users driver = passwd-file } Attempts to use the configuration result in an authentication failure. Here's an entry from dovecot.log when the failure happens: Mar 31 16:04:12 imap-login: Info: Disconnected (auth failed, 1 attempts in 5 secs): user=<jeff(a)foo.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.1.1, secured, session=<n5/ajez1FgB/AAAB> What exactly goes where to have Dovecot use the 'users' files to authenticate users? Thanks in advance and my apologies for the question. Two days of blog posts, mini-HowTo's and mailing lists has only help me discover ways to do things incorrectly. ********** # dovecot --version 2.1.7 # doveconf -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-686-pae i686 Debian 7.4 disable_plaintext_auth = no log_path = /var/log/dovecot.log login_trusted_networks = 127.0.0.1 mail_location = mbox:~/mail:INBOX=/var/mail/%u namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } ... prefix = } passdb { args = /var/mail/%d/users driver = passwd-file } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap pop3" ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd }

Hi everybody, I'm trying to backup a dovecot instance, and i'm looking for a method to "snapshot" dovecot maildir in a properly way, and backup whole snapshot in a second step (tar). I read about dsync, end, if i'm not going wrong, it dumps correctly also dovecot indexes; is it the tool i need? Thank you for any hint. Ramon

[Dovecot] possible quota bug ?
by fernando.figaro＠uol.com.br 31 Mar '14

31 Mar '14

Hi, I'm using dovecot 2.2.5 with quota (maildir backend), zlib and expunge plugins. When I list maildirsize file, I get: 1073741824S 17952 16 If I receive a new message (example: 1204 bytes compressed and 2524 bytes plain text), the quota file is write correctly (2524 1 entry). When I move the message to trash folder (or between user custom folders) the file have wrong entries: 1073741824S 17952 16 2524 1 1204 1 (this is the size of the compressed message) -2524 -1 I coudn't find any relation with the config settings causing this problem and checked the changelog since 2.2.5. Had someone had this same problem? Thanks, Fernando

[Dovecot] pop3 mailbox mirroring issues using dsync
by Nikolaos Milas 30 Mar '14

30 Mar '14

Hello, I have setup v2.2.12 to mirror mailboxes between our main mail server (vmail.example.com) and a failover server (vmail1.example.com) The problem I have is the behavior of mailboxes used on the main server (*vmail*) over POP3. I have setup an IMAP account on the failover server (*vmail1*) on such a mailbox: the mailbox is used on vmail using POP3 and the same is monitored on vmail1 using IMAP. It's mailbox *userx*(in Maildir format). I notice that all mail coming in userx mailbox on vmail, is correctly replicated on vmail1, but when it is downloaded from vmail over POP3 (and the mailbox there remains empty), the same mailbox on vmail1 is not updated to be emptied (automatically) as well, but it is accumulating mail forever (which is real problem on the mirror server). Is there a setting to enable correct mirroring of a POP3 mailbox (to empty the respective mailbox on the failover server) when mail is downloaded from it or something else should be done in this respect? Please explain. I quote below the full current config on the main server.
