I've not seen this before today but XMail fell
over during a pop3 password attack.

     pop3 connections at firewall                
Feb 10 05:00-06:00     0
Feb 10 06:00-07:00  1161 
Feb 10 07:00-08:00  9851
Feb 10 08:00-09:00   248 
Feb 10 09:00-10:00     0

Pop3 log on one server has 4987 entries all 
"ELOGIN" but nothing else.  Second server on
network has 3 similar entries from Feb 6.

Can I just add offending source ip range to spammers.tab
or is it best to block at firewall?

I believe firewall can block on connection rate so
might investigate that.

David
