[Rspamd-Users] Backup MX?

I'd like to ask about best practices revolving around setting up backup
MX server with rspamd. Mainly, how complex this setup should be?
I'll describe my specific use case here, though I'm sure this can be
generalized to a more broad use-case range. But without further due:
I have a personal self-hosted at home mailserver and I'm planning on
setting up a proper backup MX in OVH. The stack is composed of
postfix/dovecot/rspamd/clamav/roundcube, put together manually from
distribution's packages (in this case, gentoo).
I'm planning on setting up a backup in OVH and was wondering if simple
plain postfix with proper backup mx transport configuration would do, or
do I also have to setup rspamd there as well? As far as I noticed,
rspamd only checks direct sender against spam lists so I guess with such
simple setup those checks would effectively stop working, as most email
senders would try backup after noticing that primary server rejected
On the other hand, if I were to setup rspamd there, how complex the
deployment has to be as to not degrade protection measures? Do I have to
cluster/synchronize bayes/neural/other storages? Or is there a simpler
setup that I can get up to speed on backup MX that would not degrade my
Any input is highly appreciated guys :)
