Get a good spam filtering program for your exchange server, Sunbelt's
product comes to mind. Get a good anti-virus/anti-malware program that

Do something a little more proactive
Have you verified you're not configured as an open relay?
Is your firewall only allowing SMTP traffic to/from your Exchange box?

To be clear, this is the same as normal traffic. This is not being done on an
open relay, a user has given out their ID/Password to a phishing scheme, and
they are logging in remotely over OWA to send out large amounts of spam. It
