-Per default mailcow considers all networks as untrusted, except for its own IPV4_NETWORK and IPV6_NETWORK scope. Though it is reasonable in most cases, you may want to loosen this restriction under certain circumstances to allow connections from other networks.
+## Default Unauthenticated Relaying
+By default mailcow considers all networks as untrusted, excluding its own IPV4_NETWORK and IPV6_NETWORK scopes. Though it is reasonable in most cases, there may be circumstances that you need to loosen this restriction 
+As default we use "mynetworks_style = subnet".
 
-To change this behaviour override the default value of `mynetworks` parameter through the `data/conf/postfix/extra.cf` configuration file.
+## Permitting unauthenticated relaying.
 
-**Important**: Do **not** remove the networks listed as `IPV4_NETWORK` and `IPV6_NETWORK` in your mailcow.conf. You should also keep local addresses. To add `1.2.3.4/32` it may look like the configuration below:
+!!! Warning
+Incorrect setup of mynetworks will allow your server to be used as an open relay to send unsolicitated bulk email. This **will** affect your ability to send emails to other mail servers, and can take some time to be reversed. If you don't know what this is for, than you do not need it.

+!!! Note  Do **not** remove the networks listed as `IPV4_NETWORK` and `IPV6_NETWORK` from your mailcow.conf, or the loopback ranges 127.0.0.0/8, [::ffff:127.0.0.0]/104, and [::1].

+### Permitting IPV4 hosts
+To add `192.0.2.0/24` it may look like the configuration below:
+
+``` data/conf/postfix/extra.cf
+mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 [fe80::]/10 172.22.1.0/24 [fd4d:6169:6c63:6f77::]/64 192.0.2.0/24
 ```
 
-Per default we use "mynetworks_style = subnet" to only include local networks we are part of.
+### Permitting IPv6 hosts
+
+The addition of ipv6 hosts is done the same as ipv4, however the subnet needs to be placed between [ ] with the netmask appearing after it. To add 2001:DB8::/32 to be allowed to relay we would use the following configuration:
+
+``` data/conf/postfix/extra.cf
+mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 [fe80::]/10 172.22.1.0/24 [fd4d:6169:6c63:6f77::]/64 [2001:DB8::]/32
+```
