I’ve been using Thunderbird for email for years. I use it with some SMTP servers on shared hosting platforms, a yahoo account and a few gmail accounts - one with calendars. I don’t have any problems with it. Runs stable, doesn’t crash or do weird things. My only complaint would be search is a little clunky, but it works.

I had to use Outlook client for year at another job and that client was hot garbage.

All the linux stacks I was involved with over the years always had SELinux disabled as part of the base config. I can’t think of a single server it was enabled on.

I had assumed Mark Rober was a sponsored member of the alt-right intellectual dark web.

He is.

Maybe it was downvoted because of Mormon weirdo Mark Rober and not the content itself?
