Actually Roland is right, our problem isn't with MUAs but with internal hosts relaying through our main mail server.

Later.-

Why would you want to limit the max connections per IP on a per IP basis ?

MAXPERIP=1 (or 2) makes sense with SMTP on small servers. Spammers jailed in the teergrube cant connect many times simultaneously which would render the logs unreadable.

But this is very short for hosts sending lots of mail, such as internal forwarding between two servers or any host which sends more than a couple of mails per hour.

Many IMAP clients create multiple connections from the same IP when reading mail.

You need to have limits fairly high otherwise the client will get TCP

resets.

s/client/outlook/

There are some imap-implementations which use only one connection per open folder.
