Adding custom header

2012-02-21 Thread Jack Knowlton 
Hi guys.
My mailserver uses a relayhost which basically only signs messages with
DKIM and delivers them.
I would like to add a custom header, something like "X-Abuse: if spam/uce
email ab...@mydomain.com".
How should I go about, without postfix adding the header twice (before and
after dkimfilter-out)?

Thanks.

See the discussion of receive_override_options in the FILTER_README
documentation (http://www.postfix.org/FILTER_README.html).

Thanks. It does seem to work :)

Now I would like to add another header, right under the X-Abuse. How can I
perform that?
I tried with the same regex based on /^Subject: .*/, but it doesn't seem
to be adding both..

Postfix header/body_checks are not intended to provide a complete
message content manipulation system.

In this case, a Milter plug-in would be more appropriate. 

Applying header/body_checks etc. rules to output from header/body_checks
rules would be unsafe.
