What’s up, what’s down and what are you not sure about?
Let us know what you set up lately, what kind of problems you currently think about or are running into, what new device you added to your homelab or what interesting service or article you found.
I self-host my email using Mailcow, and use a VPS for it. I don’t trust my home server to be reliable enough, and the VPS providers have nicer equipment (modern AMD EPYC CPUs, enterprise SSDs, datacenter-grade 10Gbps or 40Gbps connections, etc). I use a separate VPS just for my emails - it’s the one thing I want to ensure is secure, so I didn’t want any other random software (that could potentially have security issues) running on it…
I also use an outbound SMTP relay to avoid having to deal with IP reputation. Very easy to configure this in Mailcow. SMTP2Go has a free plan for sending <1000 emails per month.
It kind of amazes me that, in this day and age, email has turned out to be the lynchpin of security. Email as a 2FA endpoint. Email password reset systems. If email is compromised, everything else falls. They used to tell us not to put anything in email that you wouldn’t put on a postcard…how did this happen?
