The remote mail server is affected by an account enumeration
The remote server appears to be running a version of Qpopper that is
older than 4.0.6.
Versions older than 4.0.6 are vulnerable to a bug where remote
attackers can enumerate valid usernames based on server responses
during the authentication process.
There is no known solution at this time.
