That was it! Return-Path: <> turns out to have been a problem with the
mutt interacting with xmail's sendmail. I've solved the problem by switching
from the xmail's sendmail to ssmtp.
The problem more specifically is way mutt calls sendmail
(with the ``envelop_from'' option set) (strace output):
333 execve("/usr/lib/sendmail",
["sendmail", "-f", "[EMAIL PROTECTED]",
"--", "[EMAIL PROTECTED]"], [/* 52 vars */]) = 0
Yielding the failed mail:

The problem is hypothesized to lie here (from SendMail.cpp::main()):
for (ii = 1; ii < iArgCount; ii++) {
if (pszArgs[ii][0] != '-')
break;
"[EMAIL PROTECTED]" works. "-f", "[EMAIL PROTECTED]" doesn't.
A simple solution of course would be to
add another variable for ``last-option seen was -f''; then, if true, we would
take a non-``-''-prefixed argument for our Return-Path: <> processing.
Or, to use gnu getopt().

After doing a little investigating, the ``DynDnsSetup'' string:
"DynDnsSetup" "members.dyndns.org,80,/nic/dyndns?action=edit\
&started=1&hostname=YES&host_id=starf.dyndns.org\
&myip=%s&wildcard=OFF&mx=mail.exchanger.ext\
&backmx=NO,fmarx,5trio5"
seems to be just the string for "updating" members current ip number.
Nothing fancy at all. Is that right?
I update as part of my login script. What would be the advantage of having
the mail-server do it?
Thank you again for a simple, powerful, secure, free mail-server. It's been
a joy to learn mail-serving with.
