[Mimedefang] HTML Emails converted as an Attachment?

[Tom D]

Hi all,

I'm using a totally basic mimedefang-filter, with nothing fancy with it, and
i'm not blaming
that this is mimedefang doing that it might be the Exchange.

But for any reason, would MIMEDefang strip the whole body of an email and
send it as
an attachment?  Email gets to the client but with the whole body being sent
as an attachment
named like: ATT####.ATT  I'm not aware of any $entity that would block html
emails or anything
And i don't have any problems with it when running at the other client, just
wanted to ask.

Thank You,
Tom D.
