Try running WireShark to see if you can find the affected PC(s). Take those off the network and scan them.

I installed wireshark but would that mean I have to open flow of mail out so I can capture?
You should be able to see that port. Run wireshark and then filter out that port. You should see that traffic coming from only certain IP addresses.
