The thing to check for is the combination of the presence of Content-Disposition or Content-Transfer-Encoding _with_ the absence of Mime-Version. Mime-Version _is_ a required header for MIME-formatted messages. A separate rule might test for Content-Type without Mime-Version but there are some broken MUAs that do that, so it wouldn't be as good an indicator. Perhaps combined with some of the USER_AGENT tests ... Just remember that Content-Length is NOT a MIME header and shouldn't be included in any such tests. ------------------------------------------------------- This SF.net email is sponsored by: ApacheCon, November 18-21 in Las Vegas (supported by COMDEX), the only Apache event to be fully supported by the ASF. http://www.apachecon.com _______________________________________________ Spamassassin-talk mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/spamassassin-talk
