Hello,
for incoming mails logging the X-Headers works pretty fine by using:
header_checks = regexp:/etc/postfix/header_checks
the file header_checks contains:
/^X-.*:/ INFO
Logfile:
Aug 17 16:56:31 mta01 postfix/cleanup[15387]: 3xY8Rz2rFJzDxk2: info:
header X-TEST: value from localhost[127.0.0.1]:54582;
from=<f...@example.com> to=<r...@example.com> proto=ESMTP
helo=<mta01.dev.local>
For sending mails using `smtp_header_checks` it _only_ logs the headers
if a connection to the destination server was established:
Aug 17 16:48:48 mta01 postfix/smtp[14811]: 3xY8Rz2rFJzDxk2: info: header
X-TEST: value
in case of a tempfail there is no header logged, is it possible to
change this behavior to always log the headers for each delivery attempt?
No header in delivery attampt:
