[BUG] Errormessage in fail2ban-log "Failed to execute ban jail 'dovecot' action 'nftables-allports' info 'ActionInfo"

### Miscellaneous first checks

- [X] I checked that all ports are open and not blocked by my ISP / hosting provider.
- [X] I know that SSL errors are likely the result of a wrong setup on the user side and not caused by DMS itself. I'm confident my setup is correct.

### Affected Component(s)

fail2ban inside docker-mailserver

### What happened and when does this occur?

```Markdown
In the fail2ban log of docker-mailserver I see lots of messages

2022-06-10 11:13:28,342 fail2ban.actions        [1173]: ERROR   Failed to execute ban jail 'dovecot' action 'nftables-allports' info 'ActionInfo({'ip': '36.137.157.218', 'family': 'inet4', 'fid': <function Actions.ActionInfo.<lambda> at 0x7f9b0dc8cb80>, 'raw-ticket': <function Actions.ActionInfo.<lambda> at 0x7f9b0dc8d280>})': Error starting action Jail('dovecot')/nftables-allports: 'Script error'
2022-06-10 11:13:30,005 fail2ban.actions        [1173]: ERROR   Failed to execute ban jail 'postfix-sasl' action 'nftables-allports' info 'ActionInfo({'ip': '36.137.157.218', 'family': 'inet4', 'fid': <function Actions.ActionInfo.<lambda> at 0x7f9b0dc8cb80>, 'raw-ticket': <function Actions.ActionInfo.<lambda> at 0x7f9b0dc8d280>})': Error starting action Jail('postfix-sasl')/nftables-allports: 'Script error'

The fail2ban jails of dovecot and postfix-sasl are empty, no bans have taken place
```


### What did you expect to happen?

```Markdown
The banned IPs should show up when listing the bans with 'setup.sh fail2ban'
```


### How do we replicate the issue?

```Markdown
1. Install mailserver v11.0.0 via docker/docker compose
2. Try unauthorized access to postfix-sasl or dovecot
3.
...
```
