> The IP lookups to connect to your MX host needs to be DNSSEC-protected Really? It does not seem necessary to require this. I mean, the security is guaranteed by the public keys in the TLSA records, right? Yes, the MX lookup and the TLSA lookups must be DNSSEC signed, but does DANE actually require the A/AAAA lookup of the server name in the MX record to also be DNSSEC signed? It does not seem necessary from a secur…

You are correct that it is not needed for security. It is also not required for plain DANE. But it is for DANE for SMTP. The reason is interoperability. Apparently, some DNS servers would not respond at all to requests for TLSA records (probably fixed in the software by now, but some infra may still run old software). If a sending mail server would request TLSA records, not receive a response, it would have to assume…

Oh, right. Thanks for explaining!

More typos: ”Staic”, “domian”, “PRT record”, “fullfill”, “ploice”, and “intrested”.

Fixed, again ;-) thank you very much :)

Lots of singular/plural errors as well. Might run the text through Grammarly or ChatGPT to rectify those.

That is the free tier. The fix is very simple. You add a credit card but not go over the free tier usage limits. Then they don't touch your stuff and you still don't pay anything. (Free tier applies to everyone including paying customers)

And then, poof, something goes wrong, Oracle bills you a kilodollar and now you need to fight _Oracle_ if you want any recourse. No thanks.

You're absolutely right. It can happen.

This seems risky, Oracle Cloud shuts down VPS they deem to be "inactive", in other words, not under any load or traffic. This would fit that category.

But then Oracle has your credit card number.

Quite a lot of critical responses here.

Personally I think this is a great write-up. Most people in tech these days appear to look down their nose and say 'oh no, you can't host your own mail server anymore'.

This write-up goes to show that it's not as complex as people seem to think.

I'd be curious to see a follow up from the author to address the other claim of this crowd - that the big mail providers mark you as spam due to no existing reputation on the IP, despite all the processes and policy being correct.

What can go wrong with a single VM? Billing explosions in the cloud are always to do with auto-scaling services that go wrong. Plus, in that case your alternative is fighting Microsoft, Google or Amazon.

I understand Squirrelmail to be basically dead for over a decade.

It was removed from Debian in 2016. But there seems to be some recent activity: https://squirrelmail.org/>, https://sourceforge.net/projects/squirrelmail/>

If you run the free tier until the intro period ends you'll know exactly what you can run for free. (There are some free credits during the trial that might skew the resurls) If you do not add anything extra after rhat, there's no visible way you can have a bill larger than 0. But you have to pay attention. Whereas before you would be told "you can't do that", later it'll just go through.
