I seem to be misunderstanding something about writing mimeheader rules. I'm trying to match these MIME headers:
Content-Type: text/plain; charset = "utf-8" Content-Transfer-Encoding: base64 Content-Type: text/html; charset = "utf-8" Content-Transfer-Encoding: base64 with these rules: mimeheader MG_CT1 Content-Type =~ /text\/(plain|html)/i mimeheader MG_CT2 Content-Transfer-Encoding =~ /base64/i The first rule fires but not the second. What have I not understood? Also, I haven't found a manual page that lists the MIME-headers the plugin can handle. This one doesn't give much detail: http://search.cpan.org/~jmason/Mail-SpamAssassin-3.3.1/lib/Mail/SpamAssassin/Plugin/MIMEHeader.pm A reference to a more comprehensive description would be gratefully received.
