Hi, all,

I want to change the existence and delete header in following format:

X-<variable>: 

where <variable> is some arbitrary strings.

I'd like to know if it is possible to do that using milter (either in
C or Perl).  I'm using sendmail 8.12.11.

Would anyone please help?  Thanks.

If you use a milter for other purposes too, then I can recommend
MimeDefang. It is very easy to delete such header entries with it. Just a
line

action_delete_all_headers("X-Spam-Level");

in the mimedefang-filter and it deletes in my case the X-Spam-Level header
tags my universities SPAM checker adds.

Thanks for all response.  Sorry that I didn't specify the question
correctly.
In the headers of the format, X-<variable>, the <variable> is
arbitrary string which is unknown beforehand, say something like this:

X-RBL-host1.domainA
X-DCC-host2.domainB
....

Thus the milter will have to take care of X-* headers.  Is it possible
to handle such X-* headers using wildcard or regular expressions?

Thanks again.
Best Regards,

Using a milter like MIMEDefang, you can go through all the headers
and delete the ones you don't like.  It can probably be done in 10 lines
of Perl.

Thanks.

Can MIMEDefang delete such changing headers which are unknown
beforehand ?  In other words, does MIMEDefang provide regluar
expression or wild card support in header deletion?  Thanks again.

As far as Perl can MimeDefang can :)

     Not quite.  What you would do is open a file called "HEADERS" (you
will be placed in the correct directory automatically) and read each
line from it.  When you find a header that starts with "X-", you would
pass that header to action_delete_header().
