I would be interested to hear folks opinions about services trying to auth
with a client.  I am especially interested in smtp, imap & pop3.

I notice with sendmail that it only tries twice and then gives up, but the
imap server that comes with RH (UW ??) keeps trying for 30 seconds before
giving up and allowing the connection to happen.

My opinion is that it is a bad thing for mail servers to try to auth as
many clients that are trying to connect are behind NAT firewalls, and the
server ends up trying to auth with the firewall (I assume iptables is not
_that_ stateful about auth as it is about ftp_data), and not the client.

At this stage I am basically rejecting auth attempts to speed the server
response up, but I wish I could find a way to stop the servers from
attempting to auth in the first place.
