We could also make the people behind that very famous. Don’t hide their names. Give them more attention.

I had long discussions with some mailcow contributors and it turns out, that some default settings can lead to an open relay if you are not careful. The biggest problem is that they use postfix. Postfix is not bad itself, as it is probably the most battle tested mail server. The configuration of postfix is a different story. And even if I prefer battle tested GNU/BSD software, postfix would be one of the rare exceptions where I would be careful.

I had a postfix running for years without issues, when I self-hosted SimpleLogin, and I fully agree with you. Once it runs, you only need to make sure that the security is managed.

I used mailcow, got an open relay immediately. Stalwart seems to do things a bit better.

I host so many services and it is not that I don’t want to learn new stuff. The effort is simply too high for a single service. And since there are very good providers which fully encrypt your data, I went this route to keep my mind off this part of my system.

One wrong config entry, and you have an open relay and a domain that can never be used for SMTP again, yay.

Actually managing an email server properly is demanding, as it is one of the most attacked services. Of course, you can also take the easy route and just pray.

I had the same thought. No real wooden joints, just pure screws and some prayers. This will probably not withstand winds above 80km/h

You know, next time you could just put them on a roof.
