I'm on the fence. I wanted to do a super simple app hosting service on the Odroid SBC. I have few services running, but two of them: Authelia and Gitea need smtp for some actually valid reason.
Would you recommend hosting for that use case?

I know some folks have concerns with the privacy of that(1), and really want to run their own SMTP. If that's the case, Mail In A Box can do the job, or you can go with a pure SMTP solution like https://github.com/ix-ai/smtp (not endorsing it -- it's just been on my radar) or a roll-your-own Postfix/Exim solution. The latter requires almost zero resources after it's set up; slap it on a $20/year VM and you're done.
1. Chasing privacy with email is a chimera. If you really want private communications, email is not the tool.
I prefer something like Brevo, which has smaller jumps per tier or even something like MXRoute for $49 per year (limit of 300 emails/hour)
Edit: Completely forgot about ZeptoMail by Zoho - incredibly good value service.
What got me interested is their integration with traefik. It just worked. Not without 9 hours of finding out the right proxy settings, but know I'm attached to it like to IKEA furniture.
On a more serious note, they showed an example of properly proxying a imap/smtp SSL connection. If you asked me before integrating it, I'd have thought it might be impossible, since SMTP has some STARTTLS negotation baked into protocol.
I only knew how to proxy SSL in HTTP and never knew that bare TCP can be used to PROXY and terminate tls as well.
