problem with sendmail -XV - VERP expansion
in [Postfix]
|
From: Keld Simonsen on 26 Jun 2010 17:02 Hi I now trached down my sendlail delivery line for my email list server, and adding the -XV option I changed it to : /usr/lib/sendmail -XV -odq -oee -oi -f $LIST-request $LIST-list < munge1$$ My problem is now that it does not generate the return addresses I want. I want the recipient address to be reflected in the envelope, instead I get the sender address: > Fromm dansk-request+dansk-list=ghz.klid.dk(a)klid.dk Sat Jun 26 22: 7:50 2010 > Return-Path: <dansk-request+dansk-list=ghz.klid.dk(a)klid.dk> > X-Original-To: keld(a)rap.rap.dk > Delivered-To: keld(a)rap.rap.dk postfix-2.3.5-0.2.20060mlcs4 best regards keld

I was talking about VERP expansion. That is that the from address gets expanded to list-owner+recipient=recipient-domain(a)site.tld I do of cause have an include line of the kind you mention ala whatever: :include:/file/name This does not get expanded as VERP addresses with each of the email addresses in the /file/name file, but only generated VERP addresses as list-owner+whatever=site.tld(a)site.tld where "whatever" is the list name. the mail does get sent to each recipient on the list, but with the list name as the sender and bounce address in the envelope. best regards keld

I checked out a few details, and the result is that turning on VERP, before sending to a mailing list alias, does not turn on VERP when delivering to the members of that mailing list (except in a very special case that involves only local recipients). It can (and should) be made to work outside that special case, but that requires a few changes to Postfix internals, and that will take more time than I have available now. There is a workaround to turn on VERP after the mailing list. For example, deliver mail to the mailing list alias with one Postfix instance, then deliver mail to the members of that list with a second Postfix instance that turns on VERP via one of the methods in message <20100626210934.27B7E1F3EA8(a)spike.porcupine.org> (this involves content filters, or the Postfix 2.7 smtpd_command_filter feature).
