I run an AWS instance that hosts my own domain mail server. I have hundreds of email addresses, and each of them is forwarded to a gmail account. (I use the myaddress+tag@gmail.com to make each one unique. I do this to identify and squash spam - if one email address becomes contaminated, I delete it and change my email on the compromised company's server. I also run a mailing list server. So my email is usually sent from a gmail.com address, and I usually receive email on my own domain. Some lessons - sending email from your own domain is difficult as you have to not only make it accepting to spammer-averse sites. You also have to protect it from sites that would LOVE to relay email through your server. As for receiving and reading email on your own domain - you have to provide your own spam filters - and this is VERY DIFFICULT. 320 billion spam emails are sent every day, and 94% of malware is delivered in those emails. That's one reason I use gmail as the way I read email.
