Uhm, one must wonder why you can't simply autoreply from the main
(endpoint) server?

You need to rewrite that individual recipient within sendmail, so that it
becomes a LOCAL address not subject to the relay.

As it should - it's relaying mail for AN ENTIRE DOMAIN. Addresses

You *REALLY* don't want to try to ALL your messages through to procmail as
if they were local deliveries and then have procmail redeliver the ones it
isn't supposed to autoreply to.
There is a procmail mantra. Please recite it with me:
PROCMAIL IS NOT AN MTA.
You will encounter an unbelieveable number of problems trying to repurpose
procmail as an MTA. You will experience unnatural hair loss and a high
blood pressure. Your medical insurance carrier will try to deny your
coverage, citing that you didn't disclose that you tried to use procmail as
an MTA.
I'd consider using the "genericstable" feature of sendmail. This way, you
could rewrite the ONE address you want to autoreply for into another
hostname (say, an alias on the relay host, rather than the same domain as
the endpoint host), and from there a regular alias could invoke procmail:
autoreply: |/usr/local/bin/procmail -m /etc/procmailrcs/autoreply.rc
(FTR, the rcfile wouldn't really need to check ^TO for a given recipient,
since mere invocation would indicate that the message was destined for that
user, and no other).
If you have inquiries about genericstable, you should post them to the
aforementioned sendmail usenet group, or engage the services of a qualified
sendmail administration expert.
