          This module exploits a buffer overflow in the W3C logging
19
          functionality of the MailEnable IMAPD service. Logging is

          not enabled by default and this exploit requires a valid
21

22
          Professional version 1.6 and prior and MailEnable Enterprise
23
          version 1.1 and prior are affected.
