[Enigmail] Problems with decrypting PGP/MIME messages

Hi!

I just tried it, complete fresh user on my Linux box, with freshly
generated private key. And the problem remained.

But I think I managed to track down the source of the problem, and it
seems to be a Microsoft Exchange 2007 server (I am not completely
surprised here...).

When I send a PGP/MIME message and store a copy of it on my local
folder, I can decrypt it fine (see the attachment test_message_orig.asc,
which is the original message source). If I copy it to the Exchange
server of my university (which I access via IMAP), the message gets
changed on the server (see the attachment test_message_altered.asc).
Suddenly the whole message consists of two attachments and otherwise
changed.

I tried a none-Exchange server (imap.gmail.com), and the message does
not get changed (except a few headers in the beginning of the message
got deleted).

Do I interprete this right when I say it seems to be a problem of the
Exchange server? Is such a problem known in general? Is it a
missconfiguration of the Exchange server or a non-alterable problem on
the site of the Exchange server?

Thanks for the help so far,
- - Martin :)
