!!! warning
You will lose the integrated fail2ban functionality when using a logging driver other than json (default).
!!! warning
In newer versions of mailcow: dockerized we decided to set a max. log size. You need to remove all "logging: xy" lines and options from docker-compose.yml to be able to start the stack.
Example:
````
logging:
options:
max-size: "5m"
```

If you prefere the udp protocol use:
```
$ModLoad imudp
$UDPServerRun 524
```
at `rsyslog.conf` and `"syslog-address": "udp://127.0.0.1:524"` at `daemon.json`.

Restart the Docker daemon and run `docker-compose down && docker-compose up -d` to recreate the containers.
### Fail2ban with Docker syslog logging driver
**This only applies to syslog-enabled Docker environments.**
Open `/etc/fail2ban/filter.d/common.conf` and search for the prefix_line parameter, change it to ".*":
```
__prefix_line = .*
```
Create `/etc/fail2ban/jail.d/dovecot.conf`...
```
[dovecot]
enabled = true
filter = dovecot
logpath = /var/log/syslog
chain = FORWARD
```
and `jail.d/postfix-sasl.conf`:
```
[postfix-sasl]
enabled = true
filter = postfix-sasl
logpath = /var/log/syslog
chain = FORWARD
```
Restart Fail2ban.
