When you click this message, it should open a more detailed view with
the rules which applied to that message.

This is not the cause of your problem - but anyway: you should check
your DKIM configuration - either the key is missing or can not be found
due to a missing or incorrect domain or selector map or you should add
"try_fallback = false;" to /etc/rspamd/local.d/dkim_signing.conf.

If you don't use DKIM at all, disable the module by adding "enable =
fale" to /etc/rspamd/local.d/dkim_signing.conf.

This is the reason why the mail got tagged as spam:

MIME_GOOD - -0.20

Which sums up to 4.8.

However - where does "KEYWORD_BL" come from? This seems not to be a
standard symbol in rspamd. Did you define this locally?

Hope this helps,
