I added an IP to the Mail Proxy Whitelist and Networks. I thought that this would set up a bypass to postscreen and rate limiting but the IP is still getting rate limited. I noticed that the postfix service has not restarted so I am wondering if settings are just not being applied once I add them to those lists. If I look at the postfix config, I can see the IP in the my_networks variable and I can also see the IP in the postscreen_access file. Do I need to restart postfix on each of the servers in the cluster when I make these changes or am I not adding the IP in the right spot to bypass the rate limit?
