I've heard of this problem before, but unfortunately, it's never happened to me until moving to KnownHost last month. Not sure how or why, but I'm getting dozens of spam e-mail per day with the return address being my own personal e-mail account. I'm getting almost 100 SPAM messages per day, but only a handful (so far) that appear to be from me. I'm very concerned I will end up being blacklisted on other sites.... Please share your advice on how to A) decrease the amount of SPAM I'm getting and B) prevent my own e-mail address (and domain) from being blacklisted for SPAM I'm not sending. I've enabled SpamAssasin in cPanel with a score of 4, and BoxTrapper. I am catching the SPAM in Boxtrapper, but after a month or so I am exhausted deleting, blacklisting, ignoring SPAM. Please Help!
