I'm new to dovecot and sendmail and my server doesn't forward mails to 'dovecot deliver' at all. I was reading http://wiki.dovecot.org/LDA/Sendmail and this http://www.dovecot.org/list/dovecot/2009-June/040353.html from the mailling list but I could figure it out myself. I someone could point me into the right direction.

I'm confused with the config for LDA. Basically what I want is every message coming in go to 'deliver' except if there's no dovecot user of course. I'm using 'local_procmail' feature right now, but I tried to comile the dovecot Mailer also.

Anyway the dovecot 'deliver' itself works fine. But I cannot receiving emails or messages don't go anywhere. All the debugging I do with telnet right now.

first I got 'User Unknown' errors in the maillog so I thought I just missing an alias/virtuser entry. So I create one and forward those to procmail. But now the messages don't go anywhere and the status is sent and I don't seem them in the /var/log/dovecot-deliver.log either, so they are stuck in the middle somewhere.

Oct 16 14:26:26 sendmail[29939]: n9GIQQAh029939: to=|/usr/bin/procmail, ctladdr= (8/0), delay=00:00:00, xdelay=00:00:00, mailer=prog, pri=31420, dsn=2.0.0, stat=Sent

I don't seem to understand how the message get to dovecot's 'deliver' from sendmail.

Some questions I have which may help to solve the problem myself:

• how can I tell the LDA to lookup dovecot users too? to it would accept it?
• do I need aliases therefore for each dovecot users?
• What would the alias look like or is this the wrong way to do it? "test.user: |/usr/bin/procmail" ?
• what's the procmail recipe which would work for maildir:/home/vmail/%u mail_location?
