I tried that.  If I logged on to xyz.com and sent "from netcom.ca",
smtp.xyz.com still forwarded the mail to smtp.netcom.ca which restamped it
"from attcanada.ca".

What bothered me is that in February they sent out a notice saying either
domain could be used and changing over to the new one would be voluntary,
and then one morning, posts submitted to lists were being returned "not
subscribed".
