My solution is to put To: uk-motss@dircon.co.uk in the headers of the
messages, and rather than stuff everything into sendmail, I have a
script that's used at the actual mailer, which talks SMTP directly;
for speed of processing it works best chattering away to smap (from
the TIS toolkit). Result - no outbound alias for the list exists.
(That's a bit of a simplification, since the old script is now built
into the list software that I wrote, but I do have it somewhere here,
and I think there's at least one incarnation of it that could be
shoehorned into a system like majordomo)
