Though the question was partially answered in another post here today, but I have a question. I just checked my email stats in whm, and it has a list of over 4600 errors, which are bounced emails. Does this mean that someone is using my server for spam? If so, how do I know for sure? And, is there a way to stop it if they are? Also, I'd love any email server settings advice to help stop this problem (if there is a problem in the first place). Thanks guys.
