Can you say Spammers?

A common trick spammers use is to search out the lowest
priority mail server (basically your backup servers) and
deliver to that machine. Typically backup servers have no
accounts on them and they are a trusted source for the main
server. Also typically backup servers do not share the same
blacklisting features as your primary server.

One trick some server admins have used is to add yet another
DNS entry for the primary server with an even lower priority
setting. This way, the spammers will hit the lowest priority
box which in fact is your primary machine and has your full
blacklists and anti-virus fighting tools.

Hope this helps.

Dale
