I'm trying to write a procmail recipe that'll auto-generate unsubscribe
messages in response to RFC 2369 compliant headers. Mail for an entire
domain is being delivered to a single user with a Sendmail virtusertable
entry. I'm seeing about 20000 messages a day, about a quarter of which
is "valid" lists (notwithstanding the fact that they ignore bounces) and
three quarters of which is spam.
Obviously, I need a way to re-create the list recipient's email address,
so this is really a Sendmail config question than a Procmail one; it is
Sendmail that determines the local username to pass to procmail on the
command line specified by Mlocal.
Is there a way to get SMTP's RCPT TO data to show up somewhere in the
headers, so that procmail can do things with it? Could I perhaps have
sendmail pass the RCPT TO address to procmail via an additional -a on
Mlocal's command line?
Pointers to relevant documentation online would be appreciated. :)
