How to add a domain to DMARC whitelist in Plesk for Linux?

Connect to a Plesk server via SSH.
Create the dmarc.conf file in /etc/psa/:

# touch /etc/psa/dmarc.conf
Open the dmarc.conf file in a text editor. In this example, we are using the vi editor:

# vi /etc/psa/dmarc.conf
Add the following configuration to the file. Replace example domains with domains that must be ignored by DMARC check:

Note: If several domains are to be added, separate them by a comma.

CONFIG_TEXT: IgnoreMailFrom example.com, example.net

## IgnoreMailFrom domain[,...]
## default (none)
## Gives a list of domain names whose mail (based on the From: domain) is to
## be ignored by the filter. The list should be comma-separated. Matching
## against this list is case-insensitive. The default is an empty list,
## meaning no mail is ignored.
Save the changes and close the file.

I tried these steps, but I still get mails rejected because of DKIM validation errors. Also mentioned at https://talk.plesk.com/threads/exclude-dkim-verification-for-incoming-mail-plesk-solution-not-working.371974/#post-936828 .

Also another person in https://support.plesk.com/hc/en-us/articles/12377454166935 states that this solution is not working.

Hi,
we need customers to be able to independently exclude a domain from DMARC checks for their own domain, i.e. to create their own DMARC AllowDomainList, rather than asking us to edit /etc/psa/dmarc.conf and forcing the whitelist on all domains in Plesk.
Can you develop this?
