Sorry for sending this to the group, but name resolution of "dmntor.on.ca"
failed from here (perhaps due to recent troubles with SuraNet connectivity,
as I have every confidence that it is properly registered and served 8-) ).
Anyway, since this is short I won't bother with trying the evil bang-path.
Someone else may have a better solution, too.

This happened to me about a year ago.  When I started a sendmail daemon by
hand while su'ed to root, the daemon would read my NAME environment variable
and use that on any mail that it forwarded.  Included below is a fix that
I wrote (and posted).  If the same thing is happening to you, this might
help.  Anyway, my problem arose when I configured a central mail server
(with exported /var/spool/mail) to accept mail from clients (which didn't
run sendmail daemons), to rewrite the host name so that mail appeared to come
from the domain, and then to forward it on.  It seemed strange that the
forwarding daemon would rewrite the senders full name to mine.  This quick
hack didn't really fix that problem directly, but did prevent it from ever
happening by preventing sendmail from reading the NAME environment variable
when started in daemon mode.

Let me (us?) know what fixes your problem.

Regards,
Chuck

P.S. If it fits your style better, feel free to substitute 
	FullName = (daemonmode) ? NULL : getenv("NAME");
for the if-else construct.  I probably will when I eventually move to 5.64.
At least it doesn't gratuitously mess up the line numbers as much in diffs.
