@bix Yeah, I have a post brewing in my mind about this…
I have a very Amish approach to technology. IMAP and Mail.app and my own domains/servers have worked well for me to 20+ years. Why change?
And, this may sound unkind but, here goes... I think people who use an email service versus hosting don't really care about email.
I really care abut it. Care enough to keep it in open standard protocols on servers and at domains I control.
I care enough that I want people to be able to email me at the same address for the rest of my life.
No features will ever outweigh that.
