So... is it safe to assume their servers are configured
incorrectly? Or should our MTA be somehow adding that
header if it's missing? Or is there some other way that our
MailScanner+SpamAssassin combo should be getting the envelope
sender information?
Your MDA should be adding it, and whatever is calling SpamAssassin
(MailScanner) should be at least faking it in the message it hands SA.
Well, MTA since MailScanner is scanning while the message is
still in the MTA phase of things.
But, here's the funny thing. If I connect to our mail server
on port 25 and submit a message manually to the SMTP server
(sendmail 8.13.7) by hand, it does get added. That is, if I
do this (edited for brevity):
$ telnet localhost smtp
helo blah.blah.emitinc.com
mail from: [EMAIL PROTECTED]
rcpt to: [EMAIL PROTECTED]
data
From: [EMAIL PROTECTED]
To: [EMAIL PROTECTED]
Subject: testing
body body body
.
then the message I receive in my mailbox will have Return-Path
added. So apparently if it's missing, it adds it, and
if it's there, it preserves it, except if it comes from
majorcustomer.com, in which case it doesn't exist.
