Have you checked to see how the Mac user sending the files to you has
encoding set on his/her e-mail program??? For instance in Outlook
Express, you have four choices: None (not recommended for sending
binary files), BinHex (Best for Mac to Mac), UUEncode and Base 64.

Encoding has absolutely nothing to do with compression. It just
assures that the file arrives to you intact so that you can actually
open it (someone brighter than I can probably explain this better, but
basically this assures that your resource fork and data fork aren't
separated -- and I think it has something to do with e-mail sending 7
bit files).

You might try having them encode the files as Base 64. To the best of
my knowledge, this does not add a three character extension; and based
on my experience works just fine with the Mac and Outlook Express --
and might solve any issues related to your NT mail server.

At the very least, it would be an easy experiment to try, and would
not require any changes except for the sender to change the encoding
default to Base 64.
