Still no answers everyone?  

I just need to know how to stop all email traffic unless it comes from these two IP ranges.

209.222.80.0/21 

and 

64.235.144.0/20

Where would I input those two strings?

Thanks,

Daryl

Daryl,

One thing you could do is blacklist an entire IP address range and Whitelist the IP addresses/ranges you want to allow to send to SmarterMail.  You could also create a content filter for a whole domain, but there is not a way to use IP addresses as the criteria for those.  You may also want to adjust your spam weights and spam filtering actions.  If the messages that are coming through are getting scored too low you could adjust the weights.  Or if they have a satisfactory score you could adjust the spam filtering actions as needed.

To just allow two IP addresses I would set up a filter at the firewall instead. That will block it all and maybe clean up the logs by not having all the other attempted connections happening all day.

I only use the built in spam filters with a LOT of GeoIP and TLD blocking at the firewall. We get very little truly unwanted spam come through.
