For some definitions of fine, sure. I run my own mail, and relay it through an AWS EC2 instance that I've used on the same IP for over 5 years. It took an exceptional effort over many months to get off the Hotmail blacklist a while back. I still wonder when emailing someone I've never emailed before if that message will go do a Junk folder, or be delivered. The benefits outweigh the costs, but it is not easy, and you can start having problems that are very hard to solve.
