yes, that's the best approach i'd say. i've learned a lot over the last
few months struggling with this mail server setup and the conclusions
are that mtas should never share a machine with other critical services
and they deserve their own local replica :)

yeah, that was mandatory for keeping the daemon running. i didn't tune
the bdb caches in the beginning ( lack of knowledge... ), which resulted
in all ldap daemons failing after some hours.
