Advice needed: dmarc setup and mail.ru (lemmy.ca)

I'm not in the security field so sorry if I seem like a newbie. Not sure where else to ask.

I setup my own email domain thing with the help of some kind Lemmy folk. I'm on Namecheap, it was a little tricky for me to set up but it seems to have been working out great.

But yesterday, and again today I got this notice from DMARC that Mail . ru is doing stuff with my account.

advice I was able to google suggest I needed to change a setting from "none" to "reject".

can anyone tell me if I've done this right? also has any damage been done by me not having this set sooner?

This appears to be a report from their mail server and is because of the rua field that you received it. By setting it to reject, you're telling them to not accept any email from someone that is spoofing your domain. I think the only other field you'd want to set is pct as it specifies what percentage of email this rule should apply.
