[Mimedefang] Header being added incorrectly

[Steve Robb]

I've had MD 2.21/SA 2.41 up and running for a while in a production
environment without any real problems (Solaris 9, Sun Ultra10, ~15,000
msgs/day) and just set up a new test server platform. The odd thing that I
noticed with the new server is that any mail that is sent through this new
machine adds a header to every message labeled - "X-UIDL:
74n!!4^&"!UJK"!g/&#!" (no quotes). The header content appears to random
characters and seems to be different for each message.

I grepped mimdefang.pl and mimedefang-filter for UIDL and didn't come up
with anything that might be adding it. Any thoughts?
