It gets even more interesting.
I CAN send mail via SMTP using my companys SMTP via their domain also on TCH, but not my own. Both are sent from the same computer (my office computer her in VN) but if I use my own SMTP via my domain on TCH it gets the rejection warning. Both domains are on server27. I can send email via my domain SMTP to myself only, but not to my company email account - that get's rejected. While from my company email account I can send anything without rejection. (This is all from the same IP)
When I went to the spamhaus.org website they said they had the IP listed because it was on the CBL. When I went to cbl.abuseat.org they did have the IP listed, but as I understand it they don't list SMTP relays, just the source IP. According to everything I've read on smamhaus.org and cbl.abuseat.org the most common reason for listings is a compromised mail server... at this point I can't see how my domain SMTP on TCH is getting blocked, and my companies domain SMTP on TCH works fine (both server27)... so I am a bit confused at this point why one works and the other doesnt. I am going to contact SBL and see if I can get any more specific information. Thanks for your help, but I'm going to keep plodding along to see if I canf ind a solution. (Hehe, I really don't care for webmail!)
