## Backup MX, Secondary MX
For whitelisting a IP-Address from the SPF test, you can create a config file(See [policyd-spf.conf](http://www.linuxcertif.com/man/5/policyd-spf.conf/)) and mount that file into `/etc/postfix-policyd-spf-python/policyd-spf.conf`
**Example:**
Create and edit a policyd-spf.conf file here `/<your Docker-Mailserver dir>/config/postfix-policyd-spf.conf`:
```shell
debugLevel = 1
#0(only errors)-4(complete data received)
skip_addresses = 127.0.0.0/8,::ffff:127.0.0.0/104,::1
# Preferably use IP-Addresses for whitelist lookups:
Whitelist = 192.168.0.0/31,192.168.1.0/30
# Domain_Whitelist = mx1.mybackupmx.com,mx2.mybackupmx.com
```
Then add this line to `docker-compose.yml` below the `volumes:` section
```yaml
- ./config/postfix-policyd-spf.conf:/etc/postfix-policyd-spf-python/policyd-spf.conf
```
