[TriLUG] Filtering and Bouncing HTML Mail

[Jonathan Hassell]

I am looking for a way to configure Exim to detect whether a message is in
HTML or in plain text, and if it is HTML, to bounce it back to the sender
with an error message.  I could also do this with SpamAssassin if it's
possible.

I'd also prefer it to be configurable per domain (I host several on this
box), but that's not 100% required.

Has anybody done this? Does anyone have ideas?

Thanks
Jon
