Hello,
I have been investigating some issues I have with a few machines and
envelope senders.
Since I want to keep envelopes intact inside my local network, I want to
do the cleaning up on my outgoing smarthost.
So after adding an entry to a check_sender_restricting, I get to see
that the smarthost receives e.g. x...@shell1.local.dohd.org as envelope
sender, and I want to change that to x...@dohd.org, the simplest case I
want to rewrite.
What have I done so far:
add the follow config to my main.cf (for Postfix 3.8.4, installed from FreeBSD
pkg):
# some debugging to hopefully see what happens
debug_peer_level = 3
debug_peer_list = 10.0.0.170,10.0.0.220,[2a06:2602:1d:40::25]
# the adding of the envelope sender to a header
smtpd_sender_restrictions = check_sender_access
regexp:$config_directory/sender_access
# the canonical mapping part
sender_canonical_classes = envelope_sender
sender_canonical_maps = regexp:$config_directory/sender_canonical
I have tested with and without, just to be sure.
local_header_rewrite_clients=permit_mynetworks
The files here:
* sender_access:
/(.*)/ prepend X-Envelope-From: $1
* sender_canonical:
/^(.*)@shell1\.local\.dohd\.org$/i $1...@dohd.org
/^<(.*)@shell1\.local\.dohd\.org>$/i $1...@dohd.org
The second line was just an attempt based on what I saw in log files. Checked
it with postmap -q to see what it does.
If I then send mail going through the relay, and check the maillog for
canonical lines and the envelope lines:
Sep 16 08:15:58 s-mailrelay2 postfix/smtpd[95962]: <
shell1.local.dohd.org[10.0.0.170]: MAIL FROM:<x...@shell1.local.dohd.org>

Sep 16 08:15:58 s-mailrelay2 postfix/smtpd[95962]: <

ORCPT=rfc822;x...@dohd.org
Sep 16 08:15:58 s-mailrelay2 postfix/smtpd[95962]: maps_find:
recipient_canonical_maps: x...@dohd.org: not found
Sep 16 08:15:58 s-mailrelay2 postfix/smtpd[95962]: maps_find:
recipient_canonical_maps: @dohd.org: not found
Sep 16 08:15:58 s-mailrelay2 postfix/smtpd[95962]: maps_find: canonical_maps:
x...@dohd.org: not found
Sep 16 08:15:58 s-mailrelay2 postfix/smtpd[95962]: maps_find: canonical_maps:
@dohd.org: not found
So I don't see any action being taken for sender canonical mapping.
Does anyone have a slight hint what logging I should be looking for, or even
better: what I'm doing wrong?
Kind regards,
Mark
