I need to change the settings on my SonicWall Pro 100 firewall.

I need to block all the incoming traffic to my exchange server, only accept certain IP’s (12 of them).

I need to know how I can do it. I have never created any rules for Sonic Wall Pro 100.

Basically all the emails for my exchange server will filter out at this company who provide spam protection. I need to make changes in my firewall to only except emails from that company.

Outgoing emails don't go through them.

My concern is that if I block everyone else (just allow those 12 IP’s), will my outgoing emails be effected as I am modifying SMTP port 25.

Many thanks

I hope my question is clear.
