[Dovecot] Stop Maildir appending to path
by Henry 28 May '07

28 May '07

Dovecot is working perfectly except for one problem. I have local users and virtual users. Local users are ~/Maildir. And virtual users are /home/vmail/domain/user. The problem is, it keeps trying to fetch virtual mail at /home/vmail/domain/user/Maildir. It doesn't exist the user/ dir is the Maildir. To get around this, I have to make symlinks on each virtual email. What should I check? How do I make it stop appending Maildir to my virtual users path? If I set mail_location to the virtual user path, it works fine. But I won't be able to get local mail. So I... have mail_location pointing to local users ~/Maildir while UserDatabase/Extrafields feature will overwrite the path for virtual users. dovecat-sql.conf: password_query = SELECT email as user, password, CONCAT('/home/ vmail/', path) as userdb_mail, 5000 as userdb_uid, 5000 as userdb_gid FROM view_users WHERE email='%u';

Hello all, I'm wanting to set up IMAP bandwidth monitoring, but I don't see any IMAP size transfer entries in the log file. How would I turn this on? Please refer me to the manual if I've somehow missed it :) Thanks, Phillip

28 May '07

I have several POP mail accounts. I have installed and partially configured Dovecot 1.0.0 on Debian sid. I am having trouble understanding some of the basics. For starters do I need to fetch my POP mail (fetchmail, etc.) myself? TIA, Paul Scott

[Dovecot] Variable expansion in LDA vs POP/IMAP
by Stephane Enten 27 May '07

27 May '07

Hello all, I'm trying to understand when exactly the variable substitution happens in Dovecot, as I get different results in the LDA and in the POP/IMAP server. Here's my general setup: - Postfix MTA, delivers mail via Dovecot LDA - users list sits in a database - mail directory is stored in the database, but with Dovecot variables inside Delivery works perfectly fine, Dovecot's deliver get a "mail" column from the database (that looks like this: /mail/01/%2LMd/%2.2LMd/%LMd/mail/%Ln/ ) and expands variables, delivers the mail into the maildir's location. Now if I try to access the mailbox through Dovecot's POP/IMAP server, it looks like it gets the right field from the database, but won't expand the variables: May 24 18:31:14 mail1 dovecot: imap-login: Login: user=<XXXXX>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured May 24 18:31:14 mail1 dovecot: IMAP(XXXXX): Effective uid=1021, gid=304, home= May 24 18:31:14 mail1 dovecot: IMAP(XXXXX): maildir: data=/mail/01/%2LMd/%2.2LMd/%LMd/mail/%Ln/ May 24 18:31:14 mail1 dovecot: IMAP(XXXXX): maildir: root=/mail/01/%2LMd/%2.2LMd/%LMd/mail/%Ln, index=/srv/mail/01/%2LMd /%2.2LMd/%LMd/mail/%Ln, control=, inbox= May 24 18:31:14 wmail1-v dovecot: IMAP(XXXXX): Disconnected Am I missing something to get the pop/imap part expand those ? -- Stephane Enten

[Dovecot] UID confusion
by Kevin 27 May '07

27 May '07

I have just finished reading the info on the wiki on setting up virtual users with Dovecot and Postfix. http://wiki.dovecot.org/DovecotLDAPostfixAdminMySQL I'm confused about the UID and GID's. In the docs it shows a user, vmail being created with a UID of 101. Then it looks like GID 12 is used for Postfix or Mail. I'm not sure which it is and would like to know. Bulldozer

Re: [Dovecot] question mailbox format
by sc2＠gmx.at 27 May '07

27 May '07

ok after playing a while now it works , but i have one problem open.. a.) now he makes for pop3 index files in /var/indexes/%u/imap/index etc... you said that is correct too if i only use pop3 ? b.) i have as INBOX file /var/spool/mail/%u set, when somebody logs in, and the mailbox exist he gets the email (from mbox file), but when the mbox does not exist he makes a directory, instead of a file like /var/spool/mail/%u. The problem is when a new mail comes and the mbox file does not exist, the mail is saved to the directory as msg and not as mbox file any ideas? Btw im using version 1.0.0 thx

[Dovecot] locking question
by Paul Amaral 27 May '07

27 May '07

Hi, I'm using Maildir with dovecot .99, I'm getting some errors with fcntl locks. Do I still need to use a locking mechanism if I'm using maildir with pop3 access. For reasons I won't go into I cant upgrade from .99 to version one at the time. I'm getting this error with some users, I have tried to manually delete the .imap.index file but the error comes back, any thoughts? May 24 12:11:21 pop imap(generalg): Timeout while waiting for release of exclusive fcntl() lock for index file /home/g/generalg/Ma ildir/.INBOX/.imap.index TIA, Paul

[Dovecot] Address extensions with dovecot LDA
by Nick Kartsioukas 27 May '07

27 May '07

Greetings! I'm using Dovecot and Postfix with virtual mailboxes, the mailbox data is contained in a MySQL database. I'd like to use the Dovecot delivery agent so I can support Sieve filters. However, I'm not sure how to get the delivery agent to work with the Dovecot auth mechanism and MySQL to do proper lookups of email addresses with address extensions (such as test-blah(a)example.com). Does anyone have a similar setup that can tell me how I might get this to work? -- Nick Kartsioukas | KF6UZB change(a)nightwind.net | NK2694

[Dovecot] Quick question on multiple access to dovecot indexes
by Adam McDougall 26 May '07

26 May '07

I have up to 4 servers that will run dovecot behind a load balancer, which means the same user might be accessing the same mailbox from multiple servers, and it seems like dovecot doesn't like multiple access to the dovecot indexes for the one user since I currently have them stored in a nfs home directory. Is this a bad thing? Must I keep a seperate index location per server? Just today I started running dovecot on more than one server like this and started seeing things in the logs like: May 25 11:19:13 boomhauer dovecot: IMAP(mcdouga9): Corrupted transaction log file /home/mcdouga9/Maildir/dovecot/public/indexes/decs/.support.In/dovecot.index.log: end_offset (1332) > current sync_offset (1244) May 25 11:19:13 boomhauer dovecot: IMAP(mcdouga9): broken sync positions in index file /home/mcdouga9/Maildir/dovecot/public/indexes/decs/.support.In/dovecot.index May 25 11:19:13 boomhauer dovecot: IMAP(mcdouga9): fscking index file /home/mcdouga9/Maildir/dovecot/public/indexes/decs/.support.In/dovecot.index May 25 11:19:13 boomhauer dovecot: IMAP(mcdouga9): Fixed index file /home/mcdouga9/Maildir/dovecot/public/indexes/decs/.support.In/dovecot.index: log file sync pos 2,1332 -> 2, 1244 May 25 11:19:13 boomhauer dovecot: IMAP(mcdouga9): Unexpected transaction log desync with index /home/mcdouga9/Maildir/dovecot/public/indexes/decs/.support.In/dovecot.index May 25 11:19:13 boomhauer dovecot: IMAP(mcdouga9): Disconnected: Mailbox is in inconsistent state, please relogin.
