There was a mistake in examples in mx_check module
(https://rspamd.com/doc/modules/mx_check.html) documentation.

Words `true` or `false` in the parameter `one_shot` must NOT be quoted.
Hence, the culprit is likely in your `/etc/rspamd/local.d/metrics.conf`
file.

You could do the same investigation by grep'ing `MX_MISSING` word in
your configs. That's why I considered message `one_shot attribute is not
boolean for symbol: 'MX_MISSING'` as a self-explanatory one...
