Is it possible to install my own mail server on digitalocean?

Question

Mail server

Please tell me, if I buy a domain name, for example, from godaddy.com without additional services in the form of mail, is it possible to independently attach my own mail server to this domain on digitalocean? I mean is it possible or do I have to pay for something on godaddy anyway? I am far from this topic, but I am able to administer ubuntu server. I don't know what to ask Google to give me the results I need.
The reason for this bike is that godaddy.com has a 100MB email limit, on the cheapest plan. To order it separately for 60 bucks a year, there is no desire, and banal - I want to try to set up the mail myself.

Answer 1

you can set up mail on Google but there is a fee of 5 bucks per box, you can also tie it to yandex here for free and all this to your own domain
so it will be easier
