You're going to have to give some more information on the message being
sent... It's about 5 years since i struggled with X.400<>RFC822 based
mail.
I suspect that the message being received (I don't even know if it's
being received as SMTP or X.400 from your message) is either a MIME
message or a X.400 message with a complex body-part.
The gateway is then converting the complex types into the corresponding
complex type, in otherwised it might be taking a P22 body-part and
splitting it into a couple of IA5 and an MS-WORD part, and then
recombining these to make a MIME message.
The difficulty happens when the gateway doing the conversion doesn't have
an appropraite filter installed, and the software authors haven't
considered providing a default encoder. this is partiticulary difficult
with x400->SMTP make since the body-part-types are tagged with OIDS which
might be specific to the site, the application, or anything one likes...
basically if you want to pass complex documents between X.400 and MIME
then you need someone very clueful running the realy system who is
prepared to add extra encoders as required.
