Really recommend this, it's very useful to us at work for capturing email from local dev environments for email testing - we run it as part of our dockerised dev setup. Means we don't have to worry about ever accidentally hitting real mail systems, while still letting us actually exercise our email sending code.
Also makes it very easy to see rendered HTML, HTML source, the text/plain part of a mailer, etc.
And as an excellent plus, the author is responsive to reasonable PRs!
I try to move over every six months to a year or so, and it's the same gripes every time at this point.
Driver support's reasonable now, and the desktop environments are generally solid enough, but things like mixed DPI work really badly on Linux, my browser nearly always tears when scrolling on my secondary display, etc.
But... the single biggest killer for me though is how badly Linux copes with very low amounts of free memory. Put 32G in a machine and it still periodically runs completely out under my dev workload and when that happens, the whole system becomes unusable and I have to hard reboot it. I'm not sure what macOS and Windows do differently, but it just doesn't happen on either of those two OSes.
I really want to have the freedom to pick and choose my hardware more, but at the moment I keep falling back to macOS.
It's a UNIX environment so it has the tooling I want and a solid GUI that works well.
