Would like to rewrite arbitrary headers

[ar...@waikato.ac.nz]

Greetings, battlers.

I would like to rewrite headers on incoming spam without having SA
prepend "X-Spam-" to them.  Two reasons:

First, I want to get rid of "Disposition-Notification-To" because many
of my users configure their Outlook to automatically honour delivery
notifications.  That creates an outgoing email when they read or
delete a spam message.

Second, I have a set of GroupWise users.  They cannot write rules on
arbitrary headers, such as "X-Spam-Flag".  Instead, they can only
write rules based on a list of headers that Novell have chosen, none
of which begins with "X-Spam-".

Sadly both of these reasons sound lame: daft Outlook users and a daft
Novell application.  However there's nothing I can do about that so
I'm going to hack SA instead.

Does anyone else have similar needs?  Is such a feature already in the
works?

Thanks in advance.

You may need to use a tool like procmail to perform this rewriting.
With procmail, at least, it would be duck soup to rewrite those
kind of headers or delete them altogether.

you can do this in many places:
- MTA. with postfix, you can use header_checks (after the content filter 
for the x-spam header) and REPLACE or IGNORE
- content filter. you can hack amavisd if you're using it.
- MDA. this is easy with either procmail or maildrop

If you're using Sendmail as your MTA, you could use MIMEDefang (a 
milter) to do that very easily.

I'm not sure what your set up is, but I use procmail and formail to 
rewrite headers.
