Self-hosting my emails again

After three years with Purelymail, I’m back at self-hosting my mail server. Not because it’s cheaper (it’s actually much pricier to pay for a VPS), but because my mails are now hosted in Europe (who knows what happens next in the USA), I have more control to configure things how I want, and I can comply with GDPR.

This time, I decided to use docker-mailserver (boring setup with Postfix + Dovecot + Rspamd with Abusix Guardian Mail + ClamAV) running on a Fedora CoreOS VPS at Hetzner in their Finland data center.

First, I migrated just a few domains to see if everything was working, checked with various tools all the security mechanisms:

https://mecsa.jrc.ec.europa.eu/

https://www.appmaildev.com/

https://www.mail-tester.com/

https://mxtoolbox.com/

And today, I migrated my main domain and copied all mails using imapsync.
