What is your ideal personal email setup?

I still am working with a central Gmail account (forwarders and aliases from different addresses) and am thinking with the new year coming it is a fitting time to make a move to improve my setup. I've always been happy to pay, but have never found a combination which felt 'right'.

So help inspire me - What is your ideal 'email stack' for personal email?

Do you have randomised disposable addresses (if so, how do you generate them? Or are you just using a wildcard?), who hosts your mailbox (or do spend the energy to maintain your own?), and how you view your mail? I have wondered about the benefits of moving to a desktop client, but have never found one for Windows which feels good to use.
