The Content-Type: header *ought* to provide this information.

This is an attempt by the spammers to bypass simple-minded text-matching blocks. One solution to this is to parse the HTML the way the mail reader would and match on the parsed version. Better yet, use spamassassin or spambayes to identify just spam. Unfortunately many people send non-spam mail in HTML or with both text/plain and text/html parts. -D -- "Don't use C; In my opinion, C is a library programming language not an app programming language." - Owen Taylor (GTK+ developer) http://dman13.dyndns.org/~dman/
