At 7:45 AM -0400 9/21/04, David Muszynski  imposed structure on a stream of electrons, yielding:
I set up a new domain and was having trouble getting mail accepted when sent to my new address. All I did was do a mail forward at to send any mail sent to my new domain to an existing account on SIMS. It was being rejected so I turned off all of my RBL servers for a day (what a SPAM nightmare) and it was still being rejected. So I double checked, and the forwarding IP really isn't in my blacklist even though that's the message I'm sending back from SIMS. Below is the full content of one of the sessions incase that helps.

Definitely no RBL checks there.

I am not aware of anything that would cause that particular message other than that SIMS sees the address in its own local internal blacklist, so I guess you have to ask yourself why you blacklisted ZoneEdit.


I'd recommend going over your local blacklist very carefully, making sure you have no typos at all. I don't recall how SIMS reacts to bad blacklist syntax, but it might be seeing a line that is formatted just slightly wrong and interpreting it to cover more space than you intend.
