[lug] Lots o' email bounces

[Dave Pitts]

Hello:

It seems that we have a new scourge, I'm getting hundreds of apparent 
bounced email messages. It seems that the spammers send stuff to the 
recipient systems with a forged return address that points to my system. 
I catch most of the stuff with Spamassassin; but it chews up so much CPU 
it is almost a denial of service attack. Has anyone else seen these 
types of errors? How do we get rid of this crap? I'm running CentOS 5 
using the default sendmail and Spamassassin.

Thanks.
