:-)  Yes, I got that.  I was wondering what *Mailman* checks.  That is 
what I don't know.  I posted the above as an example interaction since 
I've been known to confuse other's various discussions of "mail from" in 
SMTP and "from" in eml.  (I'm also aware that we're an educational 
group, and I know that at least I learn from examples.)

Cheers,
