Hi,
I want to prevent that sendmail milter rejections generates bounces
messages. Reading sendmail documentation I see "-N" option:
echo "HELLO" | sendmail -N 'never' t...@test.es; echo $?
0
Jun 8 13:51:30 server.test postfix/cleanup[597560]: 077616620F:
milter-reject: END-OF-MESSAGE from localhost[127.0.0.1]: 5.7.1 Rejected
for policy reason; from=<r...@server.test> to=<t...@test.es>
Jun 8 13:51:30 server.test postfix/cleanup[597560]: 077616620F:
to=<t...@test.es>, relay=none, delay=0.1, delays=0.1/0/0/0, dsn=5.7.1,
status=bounced (Rejected for policy reason)
non-delivery notification seems not executed (no logs related). But logs
shows as "status=bounced". This generate confusions on post-log-anilisis.
I can prenvent this "status=bounced" on logs (status=rejected)?
This is not configurable. Perhaps your log analyzer could look for
messages that do not have an
<old messsage ID>: sender non-delivery notification: <new message ID>
record. Those messages were not returned to the sender.
Note that "sendmail -N" (and NOTIFY=NONE in RCPT TO comands) disable
sender notifications only, not postmaster notifications. Those are
configured with main.cf:notify_classes, and produce similar logging:
<old messsage ID>: postmaster non-delivery notification: <new message ID>
When Postfix logs the status= value, it logs 'bounced' for compatibility
with logfile analyzers that were written when Postfix had no support
to disable sender non-delivery notifications.
Postfix 'status=' logging was inspred by RFC 3461, which uses
'failed' in non-delivery status notifications. I suppose that here
there could be a parameter setting to log 'failed' instead of
'bounced'. I would not log the REASON in the status= field; the
reason is logged in the text portion in the logfile record.
