Stuck with E-Mail install on EE

Hello EE Support.

I’m a bit stuck with the e-mail system on easyengine. I’ve started by using ee stack install --mail, and after that i’ve proceed to the vibadmin setup.

Do i need to add MX records on my host? (using digital ocean atm) I can’t acess webmail.mydomain.com, do i need to create the sub-domain for this?

Thank you for the help, this is probably a newbie question but i’m really stuck on this.

Update: I’m really a noob… Added the A record with webmail, and the mx record. Thanks!
