There is a thread in the Dovecot mailing list discussing this subject,
but I think it best to ask here aswell:
My Dovecot 2.0 configuration contains these lines
auth_username_format = %Ln
service lmtp {
unix_listener /var/spool/postfix/private/dovecot-lmtp {
user = postfix
group = postfix
mode = 0660
}
}
and I have included the lines
myhostname = server.domain.tld
mydestination = $myhostname localhost.$mydomain localhost
mailbox_transport = lmtp:unix:private/dovecot-lmtp
in my main.cf. When Postfix is asked to deliver mail to
u...@server.domain.tld
it does so using Dovecot's LMTP socket. What bothers me about this
configuration is "auth_username_format = %Ln" in my Dovecot config.
The parameter affects all user lookups, which means that one cannot
distinguish between u...@domaina and u...@domainb during IMAP login.
I wonder how I can setup a transport which drops the @server.domain.tld
suffix when Postfix delivers mail via LMTP?
