Greetings, again... I just got a reply from AT&T. They said the problem probably lies in the HELO statement in the header. (Unfortunately, I am not the Notes administrator, but...)
Our Notes server is in a private network (napcc.aspca.int), so that is the domain presented in the HELO statement. Reverse lookups find the IP address, but it does not resolve to "napcc.aspca.int" but rather to "mwro.aspca.org". Do messaging servers such as Notes or Exchange have a setting so that it identifies itself other than with its local network name? I'm sure the "internal to external" situation I have is far from unique.
