Instead of buying small VPS's like this, why not just use OCI free tier? Their ARM compute performs pretty damn good.

Yes I know it's Oracle (buuuuh), but this free tier/ARM compute is actually pretty good. Used it before to deploy stuff like Mastodon etc.

From the site:

Arm Compute Instance Arm-based Ampere A1 cores and 24 GB of memory usable as 1 VM or up to 4 VMs

Always Free 3,000 OCPU hours and 18,000 GB hours per month

I personally just use NPM in front of all of the services I make available public. It's easy and handles the let's encrypt certificates also.

From my Ubiquity router I just have port 80 and 443 forwarded to the NPM.

They "Recalled" it!... :P

Yeah, you a right. Didn't read that requirement carefully enough.

Will drop migadu into the pool of sugestions.

I would not go down the route of doing it myself. Take a look at something like: migadu if it is simple mail hosting you are looking for.
