The setting of feat_trust_pgp is confusing. By setting this to 0, do I turn
on scanning of PGP and Signatures, or am I turning this OFF
I have users using pgp (zixmail) so I need this to come through
Also, I will add msg_pgp_warning = WARNING: Unsanitized content follows.\n
to alert to this fact.
I also understand from the man that feat_boundaries must = 0
