Hi,
I'm new to procmail and am having a bit of trouble getting sendmail and
procmail to cooperate (at least I think that's what's going wrong).
The problem I'm trying to solve is this: I have a couple of different
email addresses for virtual domains that are all hosted on the same
server (charlie(_at_)tabloid(_dot_)net and
charlie(_at_)nothingspecial(_dot_)com are two of
them). They all go to my user account 'charlie' on the server. However,
one of them -- my old charlie(_at_)tabloid(_dot_)net address -- has been
completely
inundated with spam, and I'd like to stop using it ... but I don't
necessarily want to start sending bounces right away. I'd prefer to
generate an auto-reply to any messages that arrive at the
charlie(_at_)tabloid(_dot_)net address, telling people (nicely) that unless
they're
sending me spam, they should use my other address
(charlie(_at_)nothingspecial(_dot_)com).
(It might be worth noting at this point that I don't actually log in
over POP3 to the 'charlie' account, since that account has shell access
to the server and I don't like sending such passwords in the clear;
instead, the last line in my .procmailrc file forwards all messages for
charlie to a mail-only account on the same machine.)
My hope was that I could use a variation on the recipe given at
http://www.sendmail.org/faq/section3.html#3.29 to identify and
auto-respond to any messages that arrived via tabloid.net.
So I added the following line to sendmail's virtusertable file:
charlie(_at_)tabloid(_dot_)net charlie+tabloid
then rebuilt the virtusertable.db file and hupped sendmail. Next, I
added the following to my .procmailrc file:
ENV_TO=$1
DOMAIN=tabloid.net
:0f
* ENV_TO ?? .
| formail -i "X-Envelope-To: "$ENV_TO(_at_)$DOMAIN
:0fE
| formail -i "X-Envelope-To: UNKNOWN"
(The full .procmailrc file is shown at the end of this message.)
The problem is that the first condition ("* ENV_TO ?? .") is never
satisfied, and I can't figure out why. Every time I send a message to
charlie(_at_)tabloid(_dot_)net, it comes through with the X-Envelope-To: header
set
to "UNKNOWN".
I've even tried sending messages to charlie+test(_at_)tabloid(_dot_)net and
charlie+test(_at_)nothingspecial(_dot_)com, but I still don't see the behavior
I'm
looking for. It seems like procmail just isn't getting passed the '+'
part of the recipient address ... either that or it's storing it
somewhere other than in $1. (The virtusertable entry for
charlie(_at_)nothingspecial(_dot_)com just points to 'charlie' -- no
plus-addressing or anything weird.)
The logs for procmail look pretty much like you'd expect; here's what
happened when I sent a test message (subject: test #1) to
charlie+test(_at_)nothingspecial(_dot_)com:
procmail: [1507] Fri Jul 26 13:18:18 2002
procmail: Assigning "ENV_TO="
procmail: Assigning "DOMAIN=tabloid.net"
procmail: No match on "."
procmail: Executing "formail,-i,X-Envelope-To: UNKNOWN"

procmail: [1507] Fri Jul 26 13:18:19 2002
procmail: Assigning "LASTFOLDER=/usr/sbin/sendmail -oi clhmail"
procmail: Notified comsat: "charlie@:/usr/sbin/sendmail -oi clhmail"

procmail: [1507] Fri Jul 26 13:18:19 2002
procmail: Executing "/usr/sbin/sendmail,-oi,clhmail"
And here's the resulting message:
