Hi,
Spamassassin docs recommend that mail servers in transit of a message
records the envelope sender in the Received:-Header, since some of its
tests work more reliably if one can detect envelope sender rewrites
during the transit chain. This will probably get more important if
"schemes" like SRS get more common than they're now.
I find the arguments delivered on
http://wiki.apache.org/spamassassin/EnvelopeSenderInReceived quite
convincing, and will probably honor Debian wishlist request #335275 by
altering the Recipient header text:
--- old 2005-10-23 12:14:33.000000000 +1000
+++ new 2005-10-23 12:14:11.000000000 +1000
@@ -3,6 +3,8 @@
{${if def:sender_ident {from $sender_ident }}\
${if def:sender_helo_name {(helo=$sender_helo_name)\n\t}} }}\
by $primary_hostname \
+ ${if def:sender_address {(envelope-from\n\t\
+ <$sender_address>)\n\t}}\
${if def:received_protocol {with $received_protocol}} \
${if def:tls_cipher {($tls_cipher)\n\t}}\
(Exim $version_number)\n\t\
Before I do this, I would like to solicit the opinions of the exim
mailing list, and ask the developer team whether they would be willing
to do that change in exim's default as well - this only makes sense if
these records are widely deployed.
Greetings
Marc
