Should be recognized and tokenized, maybe.  I don't suppose it happens
very often in legitimate mail; might be a useful spam indicator!

BTW I'm rerunning my tests of P options (ignore case, tag headers,
process A IMG and FONT html tags) after correcting two human errors,
and the results of the first 3 of 4 reruns suggest that ignoring case
is not a good thing to do, tagging headers is a very good idea, and
processing those html tag contents helps too.  A proper writeup will
appear on my website in a day or two.
