When using dovecot for authentication of an SASL (postfix) request, i cannot use the allow_nets parameter. The IP-address of the requester is not known in dovecot.
I would like to allow sasl for certain users, others are not allowed to access via SASL. Some users can have access to imap and pop3 from certain IP-addresses.
How could i combine this in then dovecot configuration?
Since Postfix doesn't send the IP to Dovecot, there isn't anything on Dovecot's side you can do. You could try asking about this in Postfix list.. Someone at least had a patch which allowed sending local IP to Dovecot (http://marc.info/?t=119306971600010&r=1&w=2). Maybe it sends remote IP as well.
I wrote that patch. It passes both endpoints (remote & local) through to dovecot . This lets you restrict smtp-auth just like pop3 or imap using the remote IP. In my case, I had played around with a quick hack for doing per-ip realming (using the local IP) w/ dovecot-sql.
