But how do I ensure that header_checks only apply to port 25 ?
<http://www.postfix.org/BUILTIN_FILTER_README.html#mx_submission>
thank you, but somehow I cannot make it work.
My header checks work fine when I have it in main.cf (globally)
header_checks = regexp:/var/local/postfix/maps/header_checks
But when I remove it from main.cf and add last line to master.cf:
smtp inet n - n - - smtpd
-o smtpd_tls_security_level=may
-o smtpd_sasl_auth_enable=no
-o syslog_name=postfix:25
-o header_checks=regexp:/var/local/postfix/maps/header_checks
then it does not work.
That is NOT what the cited example in BUILTIN_FILTER_README says to do.
The above provides a header_checks directive to the smtp service, which
runs the "smtpd" component of Postfix and does not use that directive.
The header_checks directive is used by the "cleanup" component of
Postfix, so if you need to use different header_checks for message
submission than for inbound transport, you need to define an alternative
cleanup service and use the cleanup_service_name directive to tell the
smtpd services (typically named smtp, smtps, and submission) which one
to use. The example in BUILTIN_FILTER_README names that msa_cleanup and
uses that for the smtps and submission services, leaving the standard
cleanup & its header_checks for the port 25 smtp service.
