Is HTML mail ever anything but spam?  I added it to my sendmail spam
filter many moons ago and now don't have to wear out my "d" key quite
as much when I read email in the morning.

For your sendmail.mc file:

KParseCT regex -a<@> multipart/alternative|html|multipart/related

HContent-Type: $>CheckContentType
SCheckContentType
R$+		$: $(ParseCT $1 $: <OK> $)
R<OK>		$@ OK
R$*		$#error $: 553 HTML mail not accepted here -- Please resend as plain text -- Microsoft Weenies: to turn off HTML mail, choose Tools . . . Options . . .Mail Format . . . Message Format . . Plain text.
