mynetworks is used by the permit_mynetworks feature.
If you don't use permit_mynetworks at all (check with: "postconf |
grep permit_mynetworks"), then mynetworks can be empty.
To allow mail from local programs that send SMTP mail through the
loopback interface, you could set one of the following:
mynetworks = 127.0.0.1/32
mynetworks = 127.0.0.1/32 [::1]/128
