Oh but I have them !
Every day an email is sent out with the backup status.
Every day I got my email in the morning with the back up logs.
For years.
I associated email received to backup successful, until a month or so when my vpn broke and the emails where just “could not connect”, but it took me a while to bother actually opening the message body as it had always been the same for years.

So I’ll manage it differently, have the email subject be more explicit about a success or a failure amongst other things.
Always learning :^)

Then it turns out your monitoring system failed and FUCK IT’S BEEN A MONTH SINCE THE LAST PROPER BACKUP

Wait…
What happens if you take the cat out of the box then ?

I ended up going with Crowdsec.

The setup was a bit of a challenge as I like to do it the RTFM way abd that there is a bunch of concepts to grasp before you really understand what you are doing, but since then it’s been working pretty great ! And it’s free (as in you are providing them with data on the occurence of threats etc, so you don’t pay)

I’m properly in awe at this project. Not only does it support a wide range of protocols and runs practically everywhere, but it can play audio, video, display images and has keyboard shortcut support ???

It’s got everything I could think about and so much more.

I can’t wait to try it out !

Thank you so much for your time and for making this open source.

Full disclaimer : I’ve only ever used stalwart. Started with it and had no reason to change.

Been using it for about a year as a mail server for my services.

The set up is simple, configuration can be done through the webui or the conf files.
Creating users, mails, aliases etc is very straight forward.
Everything is pretty much painless, the documentation has almost everything you might need.
You can also configure automatic cert renewal. Something else I really like is that when you add a domain (you can have multiple) it also gives you the DNS configuration to add to your DNS server.

Honestly I’d say it’s a solid choice. On my side it’ll be part of futur projects where a mail server is needed.

Thanks that’s good to know :)

I just read a bit about it and it sounds quite interesting with the community aspect of it all. I’ll give it a deeper look later, thanks !
