Hi there.

To be honest, mail servers are not that hard to setup, they’re pretty hard for maintance and security. DigitalOcean has a article Why You May Not Want To Run Your Own Mail Server, which can explain what’s the problem with mail servers.

DigitalOcean has a lot of mail server tutorial which you can look for under Email tag.

My personal recommendation would be Postfix one. How To Install and Configure Postfix on Ubuntu 16.04 is a great tutorial.

You can also go with something like Zoho mail. How To Set Up Zoho Mail with a Custom Domain Managed by DigitalOcean DNS will cover you. Zoho mail is service something like Google offer, but it also has Free tier that’s great if you’re under 25 mail accounts (at time of writing tutorial, it was 10).

If you got any more question, feel free to ask.

Instead of maintaining your own mail server sign up with MXroute, it is a mail hosting service run by Jarland, the platform support specialist of DO. They have a 40GB storage promo that only costs $40 Biennially - But note that MXroute is not affiliated to DO.

Plenty of mail servers are happy with 512 MB (Sendmail, Postfix, Exim). Or just use Google Apps.
