How exactly do they do this? Unless the Verizon machines are on an RBL that I use, I don't think I'd be rejecting them. Plus using bogus domains seemed to get past the block. I know when I get to the bottom of this, and find that once again it isn't really my fault, I'm going to get some grief. So I'd like to fully understand what the situation is so I can go into the "meeting" I'm going to get called into with enough ammo to get myself cleanly off the hook. I'd crank up the logging on my SIMS server to see more info so I can tell what Verizon is doing back to me, but for some reason it wasn't taking my setting change earlier (no matter what I set it to, it would only log at the Problems level... I'm guessing a reboot will fix it, but the door to the room its in is behind a large pile of computers so I couldn't get to it today.) -chris <http://www.mythtech.net> ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
