Well,
i for one "resolved" the issue partially...
It has
to do with my former dns server that couldnt translate the requests from
courier...
once i
switched dns servers everything is working just fine.
there's something about courier using IPV6 by default where not all dns
servers can work with it...
and
courier does not try in IPV4 when the IPV6 request fails, that's a
bug.
