I've been running my own for about a decade or so. Recently, I finally gave up running my own outbound email, because I realized that no matter what I do, I'm still being blocked based on my IP address. I now pay FastMail 5 USD a month basically for their IP address, using them for outbound email only. Email is anyway inherently and fundamentally inadequate for security. I'd rather not use it at all now, and stop having an email address.
