Scenario and description of problem.
3 XP_SP3 Systems on standard home network. Let's call them systems X, A, and B.
System X - running Outlook 2003, both A and B running Outlook Express 6
Mail server is - RoadRunner pop-server.cfl.rr.com (POP/SMTP)
All mail systems operate normally except X==>A where A does not provide ANY attachments from X.
Meanwhile X==>B, A==>X, B==>X, A==>B, and B==A all work fine as does X==> outside world mail recipients.
That is to say, system A receives message body contents normally from X, but does not include attachments of any kind.
This is ONLY for emails to A from X. I can send a message from X to B, then forward it from B to A, and A receives it normally including attachments.
A is somehow discriminating against attached content from X, but only from X. I have not been able to find any settings on A that would cause this behavior.
Any suggestions would be appreciated.
