Re: Spam score - a sum of all listed tests or not?

It seems that you are using Rspamd as an additional spam scanner. If so,
I see some possibilities.

1) Your @spam_scanners score_factor for Rspamd is something peculiar.
2) The score reported back by Rspamd is not the sum of reported symbol
scores.
3) The amavis-internal RspamdClient should incorporate the score_factor
into the values of reported tests.

With log_level 5 you could see the raw json rspamd response. It would be
helpful to check 2).
