GSS question

Hi,

We are planning to have two e-mail serevrs located at two different locations. And we need to have redundancy. Can GSS act as DNS query resolver? Is it possible to watch or monitor connectivity of the first location ( by say hello or snmp or test packet ) so as long as first location is up that e-mail server will be used. If first e-mail server location is down it will some how direct the traffic to second location. This can be accomplished by resolving mx record to point to the secondary location.

In nutshell : if primary location is up MX will point to the first location. When primary is down, MX will point to second location.

We are also considering RADware linkProof device which does this work.

Any experience or link cisco.com?

Thanks in advance.
