Hello,
I'm running postfix (version 2.5.5, from debian lenny package)
with amavis and spamassassin for spam checks.
For amavis and SA to work, we have 2 postfix instances, the main
one running in port 25 and other running in other port 2500 that
receive mails from amavis.
In the first one, I want to apply a header_checks (a
header_check.pcre) that replaces some headers with another one.
Specifically, I want to replace X-Spam-.* headers with X-MySpam-$1
(because we are an internal server that receive mail from another one
that also run SA and I want to preserve both headers, but with another
name).
So I have write a rule like:
/^X-Spam-(.*)/ REPLACE X-MySpam-$1
in header_checks.pcre
In the main.cf of postfix at port 25 I have configured:
header_checks = pcre:/etc/postfix/header_checks.pcre
In master.cf I have a line like:
10025 inet n - n - - smtpd
...
-o header_checks=
So, second postfix instance doesn't use this header_check.
The problem I have is that both postfix instances uses this
header_check, so I have my own SA headers also renamed like X-MySpam-$1.
header_checks is a cleanup(8) setting, not an smtpd(8) one.
You can specify a different cleanup service by adding
-o cleanup_service_name=my_cleanup_service
to your SA resubmission smtpd listener, and defining
my_cleanup_service unix - - - - - cleanup
-o header_checks=
Credits to Wietse; I did not come up with this.
