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.
|
||
|
|
|
||
|
|
To change this behaviour override the default value of `mynetworks` parameter through the `data/conf/postfix/extra.cf` configuration file.
|
||
|
|
|
||
|
|
**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:
|
||
|
|
|
||
|
|
```
|
||
|
|
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 1.2.3.4/32
|
||
|
|
```
|
||
|
|

Per default we use "mynetworks_style = subnet" to only include local networks we are part of.
