[IMail Forum] spamming

[Dan from Tigerlink]

where is my system would I look to find out who was using one of my  IP
addresses last night  for spamming???. i woke to dozens of angry emails
about my system being used for spamming, but it appears the email came from
out of the country. Of course, there was no user name from my clients. It
was  masked..
