I think that would be quite interesting though after some tweaking of
the backend server. So if there is some volunteer, jump in :-)

I'm having just a pretty limited knowledge of LDAP currently so I can't
comment on that one.

when facing problems. And there are a lot of broken mailservers out ...
also the MEN & MICE survey for com TLD from February 2003
(http://www.menandmice.com/6000/61_recent_survey.html) outlines, that
68,4 % of 5000 randomly chosen .com zones are misconfigured.
