Microsoft Windows SMTP Service Malformed BDAT Request Remote DoS
Medium Nessus Plugin ID 10885
The remote SMTP server is affected by a denial of service vulnerability.
It is possible to make the remote SMTP server fail and restart by sending specially crafted 'BDAT' requests. The service will restart automatically, but all the connections established at the time of the attack will be dropped. An attacker may use this flaw to make mail delivery to your site less efficient.
