Marissa(_at_)yahoo(_dot_)com(_dot_)MANUALLY(_dot_)REMOVE(_dot_)THE.TRAILING.PARTS

less work and worries.  IMHO, it is not so much its forcing recipients
to refurbish their wit in order to discern phishes, as its rendering the
From: field meaningless, which troubles this workaround's viability.

Since the IETF already has a global white list of approved posters that
is already used by mailman, it shouldn' be hard to use the same white list
to admit traffic to the remailer and reject bogons.
