No, but as I said in my last message, I tested the whole .muttrc
possibility just now by disabling (renaming) my .muttrc and running
Mutt afresh without a .muttrc in effect at all.  Same error.

By now I'm fairly sure this is related to my having started to set up
SMTP authorization on both FreeBSD systems.  This doesn't explain,
though, why only Mutt-generated mail is affected, particularly with no
.muttrc in effect.  Pine mail sends out fine to this site.

So I see it as a three-pronged problem:  (1) WebShield refuses From:
lines containing "AUTH=<>", and WebShield just went into effect at the
destination site; (2) my SMTP installation probably sometimes sends
the "AUTH=<>" line because I started configuring that a while back
(months ago); and (3) Mutt and somehow ONLY Mutt triggers the sending
of the "AUTH=<>" on From: lines.

I hope to identify how (3) can be happening, then maybe if (2) can or
should be fixed or if "AUTH=<>" is supposed to be legal SMTP syntax on
a From: line, and finally whether the destination site is likely to be
refusing much mail as a result of their WebShield installation.
