Connection drops immediately, no clue given as to why. However, from another mail server just a few IP numbers away (in the same /24), the connection goes through just fine. The workaround was obviously to configure the first mail server to relay mail for msn.com via the second one, and to try to get Microsoft to tell us what was up. No luck on that last front though. -mm-
