However, I would much rather fix his problem than dump him--we're a new, small, and collegial list, and I want to figure this out. I've just about decided (whether it's true or not) that this is being caused by a firewall. Unfortunately, I haven't had an answer from writing to Pfizer's postmaster. If I don't get any other ideas or info by Monday, I'll tell my subscriber that he has to contact the system administrator at Pfizer himself. Thanks again for the help! -- Ione -- Ione L.
