Isn't this because of the flags on the Mprog mailer that says to output a
"From_" line, which on entry to another sendmail process forces sendmail to
insert a blank line in front of the headers it didn't see? If so, this is
why tail+2 is needed, and why wrapper (majordomo, really) doesn't... it
spawns sendmail and submits ONLY headers down the pipe.
I use procmail's formail -s instead of tail+2, myself, since it works no
matter what the flags are for the Mprog mailer entry (if using sendmail) or
with smail, or local.mail, and so on.

Ok, remarkably enough this does work, which means the blank line
is getting prepended to the message _before_ it is passed to the
command in the alias.
Surely there's a way to prevent the blank line from happening in the
first place. I find it hard to believe that everyone running a recent
version of sendmail is adding tail +2 to all their list aliases.
Or do programs like majordomo's 'wrapper' check for this and do it
if needed?
