[Dovecot] Fixing bad maildir message sizes
by Richard Platel 23 Jan '13

23 Jan '13

Hello. As stated in my previous message, we have some old compressed maildir messages with incorrect sizes in the filename. These messages cause dovecot 2.x problems. I'm trying to write a script to crawl all our messages, check the actual message size and if necessary, fix the filename. However, when I do this, dovecot gives the message a new UID on next login. If I change the filename in dovecot-uidlist, dovecot still gives a new UID on next login. If I change dovecot-uidlist and delete the index, then the UID is preserved. Re-indexing our millions of mailboxes is not a great solution for us. Is there a good way to fix this?

[Dovecot] question on "doveadm user" and pass/userdb
by Gábor Lénárt 22 Jan '13

22 Jan '13

Hi, I'm about getting to know dovecot in details, I am about the command "doveadm user". The man page shows this example: userdb: jane uid : 8001 gid : 8001 home : /home/jane mail : sdbox:~/sdbox plugins : sieve quota_rule: *:storage=150M It seems to be nice, however I never got this only: ~# doveadm user lgb@office userdb: lgb@office That's all. The dovecot test configuration works otherwise via IMAP/POP3/LMTP nicely. What I guess that the lack of extra information (which would be needed by some scripts of mine, eg for getting user's home easily from shell scripts, as it's hash based, etc) is caused because I don't pass home (and/or other settings) back from userdb and/or passdb. However I do have these in global scope: mail_home = /mailstorage/%Ld/%Ln (yes, this is not hashed at all at the momement but it will be soon) mail_location = maildir:~/Maildir mail_uid = vmail mail_gid = vmail (... and also some global quota stuffs configured in plugin section) Now, I am a bit confused: even with passdb/userdb does not return with user home or GID/UID, dovecot knows these in case of pop3/imap/lmtp access, since these information can be "composed" from those settings. But then, wouldn't it possible so "doveadm user" shows those as well, like lmtp/pop3/imap can resolve those too? Honestly, it's a bit redundant to put needed information into user and pass attrs in every dbs (I have some) when dovecot knows those otherwise ... If I interpret "doveadm user"'s goal wrong (it's just for userdb/passdb query tool nothing more), is there any tool which works in this config, displaying extra information (at least user's home), or should I create some script which just repeats the functionality of dovecot's configured mail_home resolution? Thanks.

[Dovecot] Mail logger question
by Hungerburg 22 Jan '13

22 Jan '13

I use Dovecot simply as a way, to provide an e-mail archive for people on the LAN, where they can move messages into from within thunderbird. Mails are stored in a maildir of one system user where all the people know the password of. This was very easy to setup in ubuntu 12. Today I started using the mail_log plugin to provide an audit trail. Now I am looking for a light way, to get the log reflect the different people or principals. One way is, to create users with the same ID in the passwd and shadow files, but I'd rather have them in a separate file, something like a list of aliases for the system user. Can you suggest a simple way, without going virtual users? Below the relevant info on dovecot: $ dovecot --version 2.0.19 $ dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-35-generic x86_64 Ubuntu 12.04.1 LTS mail_plugins = " fts fts_squat mail_log notify" passdb { driver = pam } plugin { fts = squat fts_squat = partial=4 full=10 mail_log_events = save delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size from subject } protocols = " imap" ssl_cert = </etc/ssl/certs/ssl-cert-snakeoil.pem ssl_key = </etc/ssl/private/ssl-cert-snakeoil.key userdb { driver = passwd } Thank you all -- peter

[Dovecot] %d in configuration file does not work
by Jens Tobiska 20 Jan '13

20 Jan '13

I am trying to set up dovecot in a postfix virtual account/domains setting. In the configuration file I would like to use %d in two places, for: mail_location = /var/mail/vhosts/%d/%n and to specify the location of the respective passwd file: passdb passwd-file { args = /etc/auth/%d/shadow } Looking at the logs, %d is empty while %n works, so dovecot is looking for something in /var/mail/vhosts//myname and /etc/auth//shadow which don't exist. Replacing %d in dovecot.conf with the actual domain name works. So, the quesiton is, why is %d empty, and from where does it take its value?

[Dovecot] [PATCH] LMTP: Permit user IDs containing recipient_delimiter
by Ulrich Zehl 19 Jan '13

19 Jan '13

The Dovecot 2.1 LMTP server currently always strips the address extension from a recipient address (if recipient_delimiter is set), meaning user IDs cannot contain the recipient delimiter character, e.g. "user+foo" is not supported. This was surprising for me, as Postfix behaves differently in this regard: It first looks up "user+foo", and only then "user". The attached patch works for me and brings Dovecot's behavior in line with Postfix. Please let me know what you think about it.
