I ran a number of IPs through the different spam lists more out of curiosity than because we were having a problem. I started off using the declude tool for checking to see if our IP's were listed anywhere. (I checked the primary IP's for different servers we have)
Anyhow, to make a long story short -- and a word of warning to all -- shortly after doing this, in some cases within hours - I started to see some odd things in our logs. Apparently some of the anti-spam bots checking our servers for relaying etc. We have relaying secured, but sure enough, all of a sudden we started having problems on a couple of these servers we had never had problems with. In both of these cases, all of a sudden we're getting reports from clients that email they are sending is getting returned with a message that the return address was rejected by a recipient mail server. Unfortunately, I can't tell from the messages which list these ISP's/hosting companies may be using. I've ran these IP's again and they still aren't showing up on any listings. But the problems with rejected emails are increasing. Anyone have any ideas on what might be the cause of this? Thanks for any words of wisdom!
