Hello,

until now I have use postfix and dovecot on the same server. Now I want/must split this both systems (server1 - postfix, server2 - dovecot).

I used dovecot auth system for postfix

## snip ##

smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth

## snap ##

but this does not work, if dovecot is not running on the same server.

you may use normal sasl setup asking another server over imap via saslauthd

/usr/sbin/saslauthd -n 5 -r -a rimap -O 127.0.0.1 ( should be ip of your other server )

I did not find any information in postfix/dovecot documentation, how I could solve this problem smart.

My only idea, but it looks like quick and dirty solution:

On the postfix system a small dovecot systems runs only for postfix sasl via /var/spool/postfix/private/auth. (Or I use saslauthd with sql or imap)

The postfix system (on server 1) delivers mails via transport map to the dovecot system. On the dovecot system postfix delivers this mails i.e. via ## snip ## dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient} ## snip ##

to the mail boxes.

Are there other ways, how I could solve this problem?

My wish configuration: postfix sends the auth request via tcp/ip to the dovecot auth system and not via a socket.

I use postfix 2.6 and dovecot 1.2.6.

Best regards, thomas polnik.
