Question Namecheap MX to Plesk

[P4R4DiSi4C]

Hello,

I'm a bit confused on how to make my mails working and managed by Plesk...

My domains, subdomains etc are managed on Namecheap. I added an MX record pointing to my Plesk webmail subdomain: https://webmail.p4sqch.net/

I don't know what to do on Plesk side now, to be able to send and recieve my mails because right now it's not working, When I send mails, I don't recieve them and if I send mails to my mail adress: [email protected] I don't recieve them either...

What is the best way to get this working ?

Thanks
