Plesk version and microupdate number

Plesk Obsidian Web Admin Se Edition Version 18.0.43

Hi Guys

Sorry very primitive question, but no my cup of tea.

I have a domain hosted on "Plesk Obsidian' the Domain is pointing to Office 365 using Microsoft Name Servers (Basically they are hosting the DNS records) from there pointing to the website on "Plesk Obsidian' using IP "A" Record.

My question is should the DNS Setting on "Plesk Obsidian" be set to "Enabled", "Disabled" or "Switched to Slave"?

When checking MXToolBox it comes up with "SMTP Reverse DNS Mismatch" + "SMTP Banner Check" + "DKIM" + "DMARC" issues that are beyond me.

I much appreciate the help.

Thanks

Ben
