email@example.com is the email address I want to configure on my server running OS X 10.6 and 10.7 on a different machine. I know there are a lot of people who are frustrated with this because Comcast can supply an email address with similar constraints for a small fee. If it is so difficult to make your server run email services then why worry about it ?? I can't get any help from the Comcast telephone support team because they are not authorized to provide such information. Having said this is there a location in the support tab of the BusinessClass.Comcast.net website that talks about ports, pop3, iMap or SMTP ?? I have the same problems that everyone else is having such as "can send email but can't receive anything." Currently, I must rent email services from Godaddy in order to have email at all. For a small fee Godaddy drops a piece of code into your DNS domain editor so I can get and send emails from, for example, a windows computer at a different location. Anywhere in the world actually. Apple has almost completely dumped email services from its newer server apps. Providing access to a group of iPads or iPhones but not a web browser. You must still have DNS configured on your local server if you want to run email services such as a PTR and so forth. I know it's only $50 a year for a professional email address. However, if you could shed any light on this difficult question I might not feel like a sick animal anymore.
