[Dovecot] Dovecot's deliver trouble (...probably bug?)
Hello everybody!
I am a Linux admin trying to move my mail system based on qmail to the software which is more spam-protected: exim4 + dovecot-1.0rc15 + pgsql . I've downloaded and rebuild dovecot from src.rpm (for fc4). During the testing stage I've discovered two troubles:
- the problem with deliver (...I'm not sure it's a really bug). Here is relevant part of my /var/log/messages :
Jan 3 10:40:37 serge deliver(serge@test.net): auth input: serge@test.net Jan 3 10:40:37 serge deliver(serge@test.net): auth input: home=/var/spool/mail/test.net/serge/ Jan 3 10:40:37 serge deliver(serge@test.net): auth input: uid=500 Jan 3 10:40:37 serge deliver(serge@test.net): auth input: gid=12 Jan 3 10:40:37 serge deliver(serge@test.net): setuid(500) failed: Operation not permitted
-- my system is fc4 based Linux. uid/gid are according to /etc/dovecot-sql.conf : user_query = SELECT maildir AS home, 500 AS uid, 12 AS gid FROM mailbox WHERE username = '%n@%d' AND active='1' I was trying to chown 500.12 /var/spool/mail -R , chmod u+s ...etc, but it does not helps. Please, help. I don't want another MDA, people adviced me dovecot as good and well tested solution. I have already spent about two work days to configure and test it...
- Because of mentioned above problem deliver generates a bounce message for exim, and here is a bug with e-mail in the header. It was taken "as is" from the queue of Exim -- have a look at "Return-path:", "envelope-from" and "Sender:" Because of these errors exim can not deliver the message back to sender. It freezes it, ...trying again, ...freezes ... etc...

Test message body.
As for POP3 with dovecot, it seems working OK. Dovecot generates mail directories according to the user data returned by SQL, and creates index files proper way - everything with given uid.gid = 500.12 ...
If you will need some extra piece of information, or my configs or logs -- please feel free to ask for it.
Any kind of help: advices, URLs, patches, etc.., are welcome.I badly need to bring up this new system as soon as possible.
Thank you in advance.

Deliver is not being run as root, so it cannot change UID to "serge" user...

I'm not a Linux user, but I often see messages like this where various enhanced security packages cause problems, have you ruled these out?
Either that or deliver is being run as user with insufficient rights. You shouldn't have to chmod the mail store, the delivery program assumes the appropriate credentials. At least that is how I understand it.
Hope this helps, Dominic

Configure Exim to start deliver with UID 500. I don't use Exim, so I
don't know how.

Since deliver isn't even started, this is probably also an Exim
configuration problem.
Hello!
Thank you, Timo and the other people answered, for the right clue. All the problems are solved!
