I was once asked to fix a Eudora Internet Mail Server installation 
that was freezing POP clients. Every client in the office froze while 
trying to download mail. Turned out that they were all on a mailing 
list & someone had sent a mail to that list with a blank body. They 
were also all using M$ LookOut Express, which chokes on messages with 
blank bodies in some circumstances. After wiping out the offending 
message, everything was okay again. So, as others have said, don't 
use M$ software. :)  To see if this is the problem, do this from your 
mail server:

-----
%telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
+OK <[EMAIL PROTECTED]>
user [EMAIL PROTECTED]
+OK
pass password
+OK
list
+OK
1 2784
2 1690
3 1353
4 1871
.
-----

You can then use the "retr" command to look at the offending message, 
i.e. "retr 4" if message #4 is causing the problem. To remove a 
problematic message, use the "dele" command, i.e. "dele 4". When 
you're done, type "quit" to exit the POP session.
