I hate to sound all snippish, but this isn't a microsoft list. If
sympatico chooses to run that stuff, that's their business, but I'd
simply refer my user to them for help.  Your logs show the message
accepted for delivery at bellnexxia.  End of your involvement.  But
as seekers after truth, let us proceed ;-)

I take it that the sender of the mail is [EMAIL PROTECTED], that
she sent one mail to [EMAIL PROTECTED] with a CC: to [EMAIL PROTECTED]
and that you expect the one to [EMAIL PROTECTED] to be relayed also
to [EMAIL PROTECTED], i.e. that [EMAIL PROTECTED] should get two
copies of the same mail, same msgid?  On *my* system, the user
software would throw out one of those as a duplicate ;-)  That's
a non-standard hack, two messages should be received.

Try conducting a controlled experiment.

1) Send an email to [EMAIL PROTECTED]  Send one to [EMAIL PROTECTED]
In the body of the email, put text like
        "This is to [EMAIL PROTECTED]   Code word "ELEPHANT""
and
        "This is to [EMAIL PROTECTED]  Code word "WARTHOG"

Are both mails received?

2) Send an email to [EMAIL PROTECTED] with CC to [EMAIL PROTECTED]
In the body of the email, put the text
        "This is to both of them with a CC  Code word "GIRAFFE""

Are both mails received?

Do (1) and (2) as a user unconnected with either sympatico or 
"domain".  (Like the user you used to send this Q to the list.)

By "are both mails received?" I mean verify by speech over the 'phone
or by a separate set of emails with the user.  "Did you get the
email about the ELEPHANT?  How about the WARTHOG?  And the GIRAFFE?
Did you get two GIRAFFE mails?"

The use of the li'l beasties to refer to the messages is a clever
trick to avoid having the user actually have to read headers and
figure out which email is which of your test cases.  It is easy
to confuse messages, but everybody knows the difference between an
elephant and a warthog.

3) Now have the user do (1) & (2) as "[EMAIL PROTECTED]" (if that's the
user).  The logs are harder for a stranger (me) to read if mail is
being sent to oneself.

Are all four mails received?

DSN doesn't work.  Don't expect it to.  Don't accept problem reports
about DSN from users.  In so many words, the last email below told
you this ... "mail relayed to non-DSN aware mailer" i.e. sent off to
Billy G's idea of a mailer.

Don't overlook the possibility that mail is getting lost by sympatico.

This gets hard to read because of all the jeffs and not knowing who
user is sending as, and from where.

Looks like that to me, too.
" stat=Sent (ok:  Message 197669801 accepted)" seems to sum it all up.
Not your problem.

This isn't you, is it?  No.  This is your user being told that
bellnexxia has failed some how.

You see this from M$ servers a lot more than from BSD ones ;-)

Again, it looks like your end did its job.
