Help Add email domain to auto complete

[bobbake4]

I find myself entering my email alot on my phone and I use a domain from my own web site and was wondering how I can add that domain to the email auto complete. Like with a hotmail email if you type @h it will fill in @hotmail.com. This list is stored somewhere and I was wondering if there is a place that you can add email domains to this list.

I have a HTC EVO 4G

Thanks
