Project mention: Alternative to MailCow | /r/selfhosted | 2023-06-04

I can recommend Docker mailserver (it also works with Podman). It is already pretty lightweight but you can even make it lighter and it has an active community as well as regular updates.

Simple SMTP server / postfix null relay host for your Docker and Kubernetes containers. Based on Alpine Linux.

Project mention: Ask HN: Those making $500/month on side projects in 2024 – Show and tell | news.ycombinator.com | 2024-01-23

https://sre.rs - DevOps course for small companies and individuals/self-hosters.
I’ve posted this previously, but it’s been more than a year since I published the course and it’s still right about $500/mon.
When I was starting all this, I had higher hopes, but it’s been difficult competing with instructors who already have tens of thousands of students and thousands of reviews - they appear on first page when you search for a particular subject and “no one” goes past the first page.
