Thank you for your replys. I agree that I don't think it is a problem with the Pegasus software, I just didn't know where else or who else to turn to.
One thing I did notice is that after I restart the computer, the software is already running and logged on as "Admin". Then I send an email and that is when there are mulitple messages sent.
I do not know how to capture a session log. Could someone share that with me? I also don't believe a spammer has access to my email server, as the only time it occurs is when I send an email out of Pegasus. If I send an email from the server it acts normally.
