Description:
ISA Server detected an all port scan attack from Internet Protocol (IP) address 216.250.24.64.

IP address mentioned is Symantec IP address which uses brightmail feature to communicate with server

My question is how can i set rule in ISA server for this IP address not to mark as port scan attack, In addition I don't want to disable port scan feature in ISA  

Thanks

Not much lee-way on the port scan option anyway as it is a global setting. On for everytghing or off for everything.

I do not believe you have an option to amend the entry in the log either though fir the same reason. In the logging section it is the same - log all or log nonce - there is no criteria, system key, script or the like that will let you select an exception.

In 2006 you get a new set of options in the configuration - general section (don't recall if 2004 had it or not) called flood mitigation. In here you could put mitigators fir a number of things but i still do not thing it would cover a spread of ports requests.

Sorry - the answer is No.
