Hello,
I'm using Postfix with Dovecot 2.3.13, and trying to get LMTP proxy to
work for authentication and delivery in the following scenario:
Incoming Mail -> Postfix (server A) -> LMTP to Dovecot (server A) ->
LMTP to Dovecot (server B)
I'm using MySQL for authentication.
I've created a user on both server A and server B, test at domain.tld
On server A, host parameter in password_query for test at domain.tld is set
to server B's address, and proxy_maybe is enabled.
Delivery and authentication to Server A works fine.
Authentication and IMAP proxy to server B works fine as well. I can
connect to IMAP on server A with credentials for test at domain.tld and
access the maildir on server B. This works surprisingly well, and is
about half the battle for me..
What I can't figure out, is how can I get Postfix to deliver mail using
LMTP via server A to server B.. Currently, mail still gets delivered to
the user's maildir on server A.
Is this possible with Dovecot alone, or do I need to use another method
to get messages to hop to server B via server A?
Any help would be appreciated..
cheers,
Vlad
