Blacklisted
We are being blacklisted by 9 different blacklist companies according to mxtoolbox. They include; Barracuda, CBL, Choon, ivmSIP, LASHBACK, NIXSPAM, SPAMCOP, Spamhaus Zen, UCEPROTECTL1. Not long after I discovered the problem this morning I had a user call and say their computer is basically under attack. I have shut down the computer. What is the best way for me to verify that it was this computer causing the issue?
Hello
It is better to remove the HD, add it as a secondary drive to another PC and scan it with updated antivirus and antimalware software.
Some examples

Write down all possible threats that these programs will find and search them to a virus database. In their decription you will if any of them is causing spamming

VEry sound advice, but in my experience nothing clears bugs out except reformatting and setting up from scratch =D
ASKER
I will reformat the computer before I put it back in use. I'm just trying to verify that this computer is the culprit for us being blacklisted

Its either someone in house doing mass mailers or your outbound security is low so people are spoofing your name.
Barracuda is often one that blocks me...
