I am running a Debian Lenny machine with Postfix 2.5.5 and Dovecot 2.0.8. Up until now I ran Postfix with the Procmail delivery agent succesfully. The machine has only local users; I am not using virtual mailboxes. Due to obvious reasons I want to switch to Dovecot LDA delivery, through LMTP.
I spend quite some time finding 'the' configuration for both Postfix and Dovecot, but without success. Find my current configuration below. Postfix receives the e-mail, but delivery through LMTP fails, resulting in Postfix sending an NDR.
I just cannot figure out what's wrong and I am not sure whether it's a Postfix or Dovecot problem either. Some log output from Postfix:
I finally figured out what's wrong. It appears that Dovecot in fact is checking the existance of user 'remy@hostname.domain.tld' in one of the configured user databases. Obviously, local users/usernames do not have the local domain added.
Adding
userdb {
driver = passwd-file
args = username_format=%n /etc/passwd
}to the 'protocol lmtp { }' block solves the issue. The only thing is that Dovecot now logs this to it's logs:
Mar 06 15:04:57 auth: Error: passwd-file /etc/passwd: User root has invalid UID '0'
Can't hurt, but is polutes the logs. Is there a way to configure Dovecot not to log these messages?
Thanks, Remy
