Hello,

in /etc/postfix/main.cf

i have this:

# network settings
inet_interfaces = all
mydomain = sub.domain.tld
myhostname = sub.domain.tld
mynetworks = all,127.0.0.1
mydestination = localhost.$mydomain, localhost
relay_domains = proxy:mysql:/etc/zpanel/configs/postfix/mysql-relay_domains_maps.cf
i want to ask if

mynetworks = all,127.0.0.1
is correct (that: all)

Here is postfix documentation regarding that parameter: Postfix Configuration Parameters

but im unsure out of that if mine setting is correct. i tried many open relay tests and all passwed, like im NOT open relay.

the server is a webserver

thx
