SMTP AUTH not subjected to unnecessary check?
Voytek Eymont a �crit : I have Postfix with SMTP AUTH with self issued certificate, it all works well (as long as I don't touch it..) I have now "allowed" some users to use SMTP AUTH, but, some of their mail then gets evaluated as 'spam' by amavisd/spamassasin scores, amongst these, 'dynamic ip' type... 6 Mar 2010 06:23

PATCH reject_rhsbl_reverse_client
This patch adds a "reject_rhsbl_reverse_client" function that uses the unverified client hostname for the RBL lookup. The idea is that this might increase rhsbl hit rates if the hostname is more frequently available. On the other hand, spam-only domains seem to usually have verifiable hostnames, so I'm not ... 5 Mar 2010 09:25

Dual Transports
I have been looking through archives and through the man pages and thought I'd go ahead and post my question. My situation is this: I need to deliver mail coming in addressed to a specific domain to two separate transports. There are no mailboxes local to the server at all.

Postfix Book
What happened to the Ralf and Patrick Book of Postfix book that seems to be out of print? Is there another edition scheduled or was the market just not large enough to keep the book in print? Is there another Postfix book recommended by the group? Thanks. ... 4 Mar 2010 20:17

Postfix doesn't fall back on other IP addresses
Hi, I noticed that Postfix doesn't fall back on other IP addresses associated with a certain MX-server when it fails to accept mail, but only uses the firs IP address it finds. If that fails, Postfix will move on to the next MX-server, but won't try any other available IP addresses for each of the MX-servers. T... 7 Mar 2010 20:41

outbound sender
We have two postfix machines, one is a (weak) MX in/out gateway with amavisd+sa+clam that falls way behind during a huge (trusted) outbound send-only distribution list. The other, powerful postfix machine is not-yet-fully configged next-up to replace the current weak MX, but we can't do that, yet (waiting for ... 5 Mar 2010 08:19
