Hello,
I run a docker container on my server. To not have all docker containers need
to authenticate when sending mail, I added
the private network range 172.16/12 to mynetworks:
# Added private network 172.16/12 for Docker
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 172.16.0.0/12
* Is this safe?
* Is there another / better way to achieve what I want?
# ip route
default via 188.68.36.1 dev ens3
172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1
188.68.36.0/22 dev ens3 proto kernel scope link src 188.68.38.242
