Subject: Eudora Pro 4.0 attachment/long filename problem

Eudora Pro 4.0 crashes when it trys to retrieve a message that has an
attachments with an extra long filename.  The length of the filename
effects the type of crash that will occur.  A filename of greater then 233
characters in length will cause an illegal operation.  However, a
bluescreen of death occurs and a reboot is necessary if the filename is
exactly 233 characters.

Heres how to recreate it on Windows 95.
1. Create a file with a long name(>=233).
2. In Eudora, send an e-mail to your self with the new file attached.
3. Now check your mail, Eudora should crash when it starts to download the
attachment.

And since Eudora crashes before it deletes the message from the server you
will have to do this in order to check your mail again:
1. Telnet to your mail server.
2. Type USER yourusername, hit enter.
3. Type PASS yourpassword, hit enter.
4. Type DELE 1, hit enter.
5. Type QUIT, hit enter.

The same bug is apparently in version 3.x as some funny person at my office
just exploited it...
