Philip, thanks very much for responding to this. In a way, it's a relief
to know that haven't been missing something obvious (apart from the fact
that I've probably been looking in the wrong direction altogether!)

It's interesting that no one's mentioned this before, but I take the
point that (particularly on a multi-user system) this sort of thing is
probably better done using the MUA than the MTA (up to now, I've
predominantly been using Turnpike under W98, but it's fairly limited in
terms of mailing list support: Ximian Evolution under Linux seems to
offer rather more in the way of possibilities.)

I had a look at using a headers_rewrite line in SMTP transport: however,
I couldn't see how to get at the envelope address within the right-hand
side of the rewrite rule. ($local_part and $domain seem to be still set
to the alias name and the local domain.)
