    Actually, "multipart/alternative" messages don't necessarily
contain HTML attachments, some Sun mailers f.i. send "text/plain" and
"text/enriched" alternatives.

    There are a few other problems with the above recipes.  Here's a
more realistic version:

:0 h
*     ! ^FROM_DAEMON
*  $  ! ^X-Loop: $USER@$HOST
* BH ?? ^Content-Type:[         ]+text/html\>
| (formail -rA "X-Loop: $USER@$HOST" -I "Precedence: junk"; \
         echo "You have sent a mail in HTML format, please \
resend it in plain text format.") | $SENDMAIL -oi -t
