Recently I had to switch the IP address of my postfix server from 192.168.0.125
to 10.10.10.125.
After changing the IP address at the server level and rebooting, I am now
seeing the following in the logs.
I did not change anything else in the postfix configuration except adding
10.10.10.0/24 to the mynetworks file.
Any constructive assistance is greatly appreciated.
