The remote server is vulnerable to information disclosure.
The remote POP3 server (probably intellipeer pop3 server) is
vulnerable to an account enumeration issue.
If an attacker attempts to log into the remote host by submitting a
bogus username, then the server will reply with a specific error
message if the account is nonexistent, while it will reply with
another message if the account exists.
An attacker may use this flaw to set up a brute-force attack against
the remote server to obtain a list of valid user names and accounts.
