Howto add extra networks to mynetworks

[doets001]

I use PERMIT_DOCKER=container and so mynetworks is filled dynamically with the container IP. How can I add an extra network to the mynetworks and also keep the PERMIT_DOCKER=container working.
I can overrule mynetworks by adding it to the postfix-main.cf, but then it will completely overwrite the value with what I add in the postfix-main.cf.

Put something like this in your user-patches.sh script should work:

CUSTOM_NETWORK="x.x.x.x/xx"
postconf -e "$(postconf | grep '^mynetworks =') $CUSTOM_NETWORK"
echo "$CUSTOM_NETWORK" >> /etc/opendmarc/ignore.hosts
echo "$CUSTOM_NETWORK" >> /etc/opendkim/TrustedHosts
