Question With Plesk upgrade, do I need to change DKIM and DMARC?

[CobraArbok]

Server operating system version

Ubuntu 22.04.1 LTS

Plesk version and microupdate number

18.0.50

Since I continue to have problems with SPAM, I'm wondering if I should change the TXT records for DKIM and DMARC.
DNS is managed by the ISP and not by Plesk.
Thanks in advance.

DKIM is used to sign your outgoing emails, DMARC basically tells the servers what to do if it doesn't pass checks (route to your inbox, spam folder, whatever). You could change your DKIM if you wish but that should be the case if someone is spoofing your emails successfully but usually isn't needed. It's nice to have it rotated out every so often though but isn't required but best practice states you should rotate them out every 6 months

@scsa20
I asked because with the new 18.0.50 update the default policy has changed, but only for new domains.
I was wondering if it is appropriate to do it also for those who have already created them.

Like I mention, not a requirement but I'd probably do it anyways. Best practice is to rotate every 6 months after all.
