I dumped Proton and moved to selfhosted email using mailcow. Moved my calendars and contacts over to Nextcloud since I already had it run for files.
Some will say self hosting email is not worth the trouble. I disagree. Once you have the DNS records all setup correctly its just a matter of keeping the software up to date. With mailcow that’s usually a monthly update using the included update script. Also setup something like crowdsec to watch your logs and block the script kiddies. Also don’t even try sending email from your server itself, save yourself the headache and use a relay service.
Please at least put Librewolf and Mullvad in there. If you’re feeling generous, even TOR browser.
Has Waterfox resolved their security issues?
It is mentioned in the deep dive :) https://lemmy.world/post/27983334
Waterfox was bought out by an advertising company, but they became independent again.
