I made a LOT of tests and it doesn't work 100%. I introduced 8bitmime
support in the early 2.3.0 alpha days, but unfortunately because of
james bugs and because of javamail bugs we had to remove it before
releasing. After javamail fixed the reported bugs I reenabled 8bitmime
support but we found another problem with javamail. We had to wait for
1.4.1 final. IIRC the current trunk, including an updated javamail,
should be probably 8bitmime compliant.

The critical scenario to be tested is receiving an 8bit mail via SMTP
and send it to a non-8bitmime server: james server have to convert from
8bit to 7bit.

No, the critical component is the RemoteDelivery and the underlying
javamail. Then input chain should already be ready for 8bit support
(since 2.3.0).
