Find an email provider, sign up/pay for service, and use it. I recommend buying a domain, so you can have a fairly static email address even if you end up changing providers later on. Rolling your own email service never seemed worth it to me. You'll have to deal with backups/recovery, maintenance, and any quirks associated with the big mail places rejecting mails from your service. I'm almost certain someone will chime with "but it's not bad!", well, it's not bad until you're on vacation and suddenly your mail service goes down and now you have to either go without mail (stuff sent to you will be rejected), or stop what you are doing to fix it.
