I've searched the archive, and Ben Parker also gave me this link:

We're now running ListServ Classic, at 14.4, so I should be able to do this now.

I have a list we use for testing, so I used the web interface to
create a listname.mailtpl file, and put this into it:
.BB
&*TO, if you report this as spam, I'll know about it.
.EB

(like I said, it's a test list)

The web interface took care of putting:
>>> BOTTOM_BANNER Appended at the bottom of all non-digest messages
at the top of the file.

I then added Mail-merge = Yes to my configuration for that list, and
finally (based on a glimmer of understanding from the developer's
guide), added EMBEDDED_MAIL_MERGE=1 to my go.user file, and restarted
listserv.

I'm getting this error:

-> XMRG FROM:<[log in to unmask]> VERSION=1
502 Error: command not implemented
5 Jan 2006 20:13:56 >>> Error X'00C00FB3' enqueuing mail for delivery <<<
5 Jan 2006 20:13:56  -> Severity: Error

5 Jan 2006 20:13:56  -> Abstract: Unspecified error (502) - See RFC821 et seq.


After you finish laughing at me, could someone tell me what I've
omitted, or done wrong?

Many thanks.
