Reading this thread made me recall a possible way of providing the envelope
recipient to procmail. (I'm not sure if it will work--and I don't have time
to check it at the moment. I did a quick scan of the bat book and see
sections about macros not surviving queuing, etc. However, it is worth a
try, if you have the time).

You might try adding the following at the *bottom* of your sendmail mc file:

LOCAL_CONFIG
H?l?X-Rcpt-To: $u

(Note: the letter between the two question marks on the H line is a
lower-case l ("ell" ... L ...), which stands for "local")

I *think* it should insert a header in the incoming e-mail that looks
something like:

X-Rcpt-To: ben@xxxxxxxxxxx

where ben@xxxxxxxxxxx was specified during the SMTP conversation with the
command:

RCPT TO:<ben@xxxxxxxxxxx>

I haven't had time to

1. determine if this works at all
2. see how it behaves for e-mails delivered to multiple local recipients
(where the SMTP conversation is something like):

=============================
ehlo aol.com
mail from:<frodo@xxxxxxx>
rcpt to:<ben@xxxxxxxxxxx>
rcpt to:<scott@xxxxxxxxxxx>
rcpt to:<martin@xxxxxxxxxxx>
rcpt to:<alvin@xxxxxxxxxxx>
rcpt to:<godwin@xxxxxxxxxxx>
data
From: Good Guy <yourfriend@xxxxxxxxxxx>
To: info@xxxxxxxxxxx
Subject: How are you today

I gotcha, you sucker!

Bye
Good Guy
=================================

If someone has time to send to multiple local recipients, then check each of
their mailboxen and see if each recipient has his/her own
X-Rcpt-To: [me]@example.com

(where [me] is the person named in the RCPT TO command),

then you *might* be able to test for the X-Rcpt-To: header in procmailrc.

Sorry I don't have time to try this out completely. I hope it doesn't end up
being a wild goose chase.

Ben

(P.S. Even if this doesn't work perfectly, it might give someone else an
idea. I might have more time over the weekend to try this further.)
