You do not need 100% uptime to receive mail. Because email is store and forward, other server will retry for a reasonable time.
The most complex part is setting up all the DKIM and friends to make your outgoing mail authenticated.
- GordonS 7y agoWas going to say much the same - other mail servers will retry failed sends for several days. Setting up the basics is relatively straightforward, but I found it tricky to setup TLS correctly for SMTP and IMAP, and DKIM and SPF were horrible to configure and get working right! I've been running my own mail server for 15 years or so - I really wish Mail In a Box had existed back then!
