You should see "Authenticated $username, session treated as local."

It also is helpful to run a script using a command-line POP3 client (I
have  used  Getmail.exe)  against  all  of your mailboxes to check for
($username == $password) or ($password == "password") or ($password ==
<other  extremely  obvious cases>). You can't apply much intelligence,
but you can catch obvious vulnerabilities. Be sure to use command-line
options to avoid retrieving any actual mail!
