X-Spam-Report:
* 2.4 RDNS_NONE Delivered to internal network by a host with no rDNS

How can I disable this rule ?

Spamassassin support said create this line into C:\Program Files (x86)\Parallels\Plesk\Additional\SpamAssassin\etc\mail\spamassassin\local.cf file

So, you have performed all resolution steps from https://kb.plesk.com/en/128586 and it didn't help?
Have you asked help from Plesk Support Team in this case? https://cscontact.plesk.com/form/32/?Product=Plesk

Hello,
None of the suggested solutions worked for me. I had to add several domains in the whitelist in Server-Wide Mail Settings.
I would prefer something less wide...
Is it possible to adjust SpamAssassin rules in a Plesk installation?

System: Plesk 12.5.30 Update #36 on W2k8R2

Thanks
