I have been getting some complaints from my hosting company that people have been receiving alot of spam from my server, and the domains on the server. Obviously I am not sending this spam on purpose, and I'm afraid that I might have been hacked. How do I check to see if the emails are actually being sent from my server, and not simply being forwarded with my address in the "from" section?
If it turns out that I am being used to send spam, what would you guys suggest I do to get these guys out of there? I am using linux and ensim.
I really appreciate any feedback you have, as I have no experience with this issue.
