Why don't you check your maillog files to see where the stuff is coming
from? Listening only on 127.0.0.1 doesn't help if one is running an
insecure webmail application or provides other avenues of mail access.

Also perform an nmap and nessus scan from another machine on the network as
well as a machine from outside your LAN. You might be surprised at what
vulnerabilities you have wide open.
