Expected behavior

Normal startup of Haraka

Observed behavior

Error message at the top

Steps To Reproduce

1. Install Haraka
2. Configure Haraka with Redis and LImit plugin
3. Try to start

System Info:

Haraka	Haraka.js — Version: 3.0.2
Node	v20.9.0
OS	Linux mail 6.1.0-13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.55-1 (2023-09-29) x86_64 GNU/Linux
openssl	OpenSSL 3.0.11 19 Sep 2023 (Library: OpenSSL 3.0.11 19 Sep 2023)

Additional context

I could not install the node hiredis Package as required in the documentation. I'm running Debian 12 and with that, Python2.7 has been removed from the OS. Python 3 is not supported by hiredis. Even that, hiredis is deprecated since at least 4 years.

Found the issue!
[NOTICE] [-] [core] the plugin max_unrecognized_commands has been replaced by 'limit'. Please update config/plugins

Removing this plugin from the config resolved the problem and the server has started. I will see if it even works without hiredis.
