The above recipe is a quick hack, but I don't see much more to look at (per rfc2045) in the headers. If the message Content-Type is multipart then the boundary string is required, and I think the other information in that header line is superfluous to this task. A "bare" mulipart section (no content-type or similar in the body) should default to plain text or rfc822, so I don't think the inserted "part" needs to be any more complex. Maybe add a check for MIME version 1 in the headers? Beyond that, the recipe will only match if there's a terminating boundary line; is there more to check to see if it's valid MIME? -- Ken Irving -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
