The scope of the relevant implemented functions are to determine if the
(on-wire) mail headers are suspicious or not, and do so reliably.  We
can add a slew of other functions for other types of DWIM
suspiciousness, of course, but that's outside the remit.

(For instance, if you wish to implement a filter that looks for
suspicious emails, you'd typically find anything that looks like an
email, see whether it can be RFC2047 encoded, encode it, and then call
the -email-suspicious-p function.)
