Hopefully it also means they are more likely to stay up. During one of the next feats I downloaded a few demos to try later, but as soon as the fest ended I need to purchase to play some of them. I guess as the demo was just the main game, but set as a demo.
If you don’t mind having email go through Gmail etc, then you might not want to full host, but just run a local IMAP server. There are some pop to SMTP solutions you can use to pull your emails (fetchmail.) you can then use your account as an outbound relay. Keep in mind you’ll only be able to set this up for a single account if you use something like Gmail.
If you buy a business product like workspace or m365, you should be able to setup relay/hybrid connectors for multiple accounts.
