        [Tim McCarthy]  No. SMTP servers do not understand the contents
of the mail. They don't have the ability to determine who gets mailed
and who gets copied - that's a mail client function. Some of mail client
differences you're seeing may relate to the different client
capabilities - some are SMTP clients, some are MAPI.
