How can a plugin add message-specific headers to an email?

[Alban Deniz <al...@baker-research.com>]

Hello,

I'm developing a plugin, and need to add message-specific headers to the
email.  Because the headers are different for each message, adding a
"add_header" line in the .cf file isn't what I need.

I did find the put_metadata method, but invoking it in
Mail::SpamAssassin::Plugin::extract_metadata() didn't work.  Here's the
code:

        sub extract_metadata {
        
         my ($self, $opts) = @_;
        
         $opts->{msg}->put_metadata("X-Extract-Metadata", "Test
        header");
        
        }

I was hoping to see the header "X-Extract-Metadata: Test header" in the
email, but that didn't happen.

Is there any way to make that happen?  I looked over the documentation,
other plugins, and developer email lists, but didn't find an answer.
I'd appreciate any help (suggestions, references, etc).

I tried this using the spamassassin command line using SA 3.2 on Fedora
7, and also SA 3.2.4 on Ubuntu 8.0.4.

Thanks,
Alban

Plugins can't directly add headers to the message rewrite process.
However, the plugin can create a tag which you can setup to be added
w/ add_header.

ie:

$permsgstatus->{tag_data}->{FOO} = "foo";

then

add_header all Foo _FOO_

will add X-Spam-Foo to all mails.
