my mom's email software (outlook express) out of work
the reason is because there's email which has only headers but not body.
when use dos to telnet to port 110 and use retr to get those emails, the connection will be disconnected.
but you can use "top 24 10" to check email#24.
then use "dele 24" to delete it.
I think it's because she didn't have outlook express patched.

the debug info is as follow:

top 24 10
+OK
