Thanks for your reply, it's not so much a problem for me, 
just that when I have some email problem, I often need someone else
to point it out to me, as from my perspective, everything is working
fine!  :-)

	It does for most things, but not for 'Mail-Followup-To'.
Never seen it on anyone else's email...

	Really?... so sendmail should strip off duplicate addresses.
I wasn't aware of that.  I'll have to try it.

I see others who sign their email, but hers is the only one that
comes through in an attachment.

So wondering why her email in particular comes through that way.

My "weird" Thunderbird mail agent...hmmmm...it may be old, but
first time I've heard Tbird called weird.
