ubuntu hardy SPAM issue

I have one person receiving a lot of non deliverable email messages.
They have been blocked via Barracuda and UCEProtect.
I created a block rule for Port 25 in my Cisco Router. This is what is being blocked.
The MAC address is that of the router and the server.
[ACCESS_RULE]: IN=eth0 OUT= MAC=50:3d:e5:a2:40:d4:00:1
How can I troubleshoot this to determine where the issue is coming from. No changes on the server. This started about a week ago.
