Right.  But it shouldn't matter what sort of random cruft Pegasus (or
any other client mailer) sticks in the From: line; when the Netcom
mail relay processes it, it should rewrite the From: line to a
canonical form.  That's trivial, and most ISPs seem to do that.

It would seem that their support burden would be greatly lessened if
they just fixed their mail relays to take care of this, instead of
trying to support every !~@#$% PC mailer out there.   But this is
Netcom we are talking about here, who is not exactly known for their
cluefulness.
