The path of least resistance might be to try the gmail account for the flyrotary list, which is the ONLY thing I have a problem with.  Otherwise, Bellsouth has been just outstanding.  Fast, reliable, etc, except when dealing with the lancaironline server.   I just wish I knew enough about how this all worked to figure out where the problem really is.

Rusty, I guarantee that even if you knew what you were doing there'd be no way you could resolve this problem yourself, unless the problem is on your PC. SMTP is a very simple and very old protocol that contains no delivery guarantees, security mechanisms, or other features we expect from software today. All it does is send a message from one server to another. The message may go directly to the recipient's (or mailing list's) e-mail server, or it may bounce through six servers on its way there. Either way, the sender and recipient are not part of the actual transaction, so you aren't provided with the debugging information you'd need to analyze the problem.
