Thanks Matt and Sean for your replies which have answered my question.
Thanks also for holding back on the scorn and sarcasm!
In my defence, can I point out in closing that I *did* do all the
searches suggested some months ago and, with help, got a successful
Sircam/vulnerable attachments blocking procmailrc working. This time I
just wondered if there was an easy to protect users from sending these
as well as receiving them; since you suggest this is rarely done and
not a good idea I'll live without it.

Uh, NO. If you see 'man procmail', you'd see that by setting
sendmail up
to have a procmail mailer (separate from Mlocal=procmail), and
adding some
sendmail rules, it is possible to invoke procmail via a sendmail
rule
(which can apply to outbound messages), but this isn't the
"standard"
procmail config - it requires some hacking of the
sendmail.cf. Consequently, an incorrect alteration can hose ALL
YOUR MAIL.
See some FAQ-type items I have at:
<http://www.professional.org/procmail/smtp.html>
It IS possible to invoke procmail - it just requires alterations to
the MTA
config, and if you don't have a clue how to make those changes, when
the
manpages give explicit examples, then you're unlikely to find anyone
here
who will be willing to spend the time explaining it.
I'm a procmail newbie but a kind mentor helped me set up virus
filtering on my RaQ4. This is designed to stop emails with
undesirable
attachments and also to stop Sircam by looking for patterns in the
body of the email. It's proved to work well for a few months.
A quick search of deja^H^H^H^Hgoogle for "sendmail.cf sircam"
reveals a
number of interesting posts. Among them:

Web searches are interesting things if you use them...
