Hi,

We have a Sonicwall 3600 with SonicOS Enhanced 6.1.1.9-30n. Recently we had a virus on one of our computers and the result was it sending emails out and blacklisting our IP. Is there a way to set the sonicwall to only be able to send email from our Exchange servers internal IP and block everyone else behind it?

Thanks!
