During rollover with TTL rspamd creates a new keypair and set an
existing keypair to expire in some time (can't remember exactly what was
that time - 1 day maybe).
For some amount of time, till an old keypair expires, Rspamd inserts 2
(or 4 with dual rsa-ed25519) DKIM signatures - for an old key and for a
new key. It is done to ensure that all DNS caches update public key to
verify new key properly.
Hence, new key generation is something that is absolutely expected from
a rollover procedure.
