Still having muchos problemos with my Exchange 5.5 server.
Situation is that previously reliable distribution lists have ceased to
work and they're bouncing straight back to the sender with the following
Source: MSExchangeMTA Event: 290 Description: A non-delivery report (reason
code unable-to-transfer and diagnostic code content-type-not-supported) is
being generated for message <address>. It was originally destined for
<address>; <recipient>, and was to be redirected to. [MTA DISP:RESULT 16
I know it's something to do with X.400 but WHAT.
I've deleted people from a distribution list and then I can e-mail them and
I've tried numerous other things but I'm really stuck now......HELP
