Allow html messages for spam.whitelist.rules

[Richard Alexander]

Is there any way to allow html for anyone in the spam.whitelist.rules
list?  Maybe a stupid question, but i am a little confused as to the
difference between: Spam Actions = deliver striphtml, Convert Dangerous
HTML text = yes, and Convert Html to text = yes.  We have internal users
that have html signatures, etc that we would like to allow, but do not
want PORN html coming through.
