I have emails with subject:
Subject: blah blah [Our Ref:XXX99999]
I would like to have that changed to:
X-Our-Ref: XXX99999
Subject: blah blah
I can add the header with header_checks:
/^Subject: .*(\[Our Ref:[A-Z]*[0-9]*\])$/ PREPEND X-Our-Ref: $1
I can change the subject with header_checks:
/^Subject: (.*)\[Our Ref:[A-Z]*[0-9]*\](.*)/ REPLACE Subject: $1$2
But it seems I cannot do both. According to man header_checks PREPEND
and REPLACE "inspect the next input line", which will explain why this
does not work. As far as I can tell I cannot have 2 PREPEND acting on
the same header.
Is there a work-around for this?
Not inside postfix. As you've found, only one action is
allowed per header.
You can pass mail through postfix twice (just use postfix as a
content_filter) and do the PREPEND first time through, and
munge the Subject: the second time (requires separate cleanup
services in master.cf for different header_checks; see the
archives). If you're already using a content_filter, you get
this for free.
Maybe there's a content_filter or milter that can do what you
need; mimedefang is a first guess.
