it's not what your hoping for, but anyone in your friends list will auto fill when you send a mail. Enter the first letter of their name and if there aren't several people in your friends list with the same first letter you wont have to type anymore. IF there are you'll have to type enough letter to narrow it down to the one you want.
I believe it's Friends list and Guild list... You could check out Postal - it adds a pull-down menu for you to select names from your friends and guild lists, but I don't recall off the top of my head if it lets you add names to it that aren't on those lists...

Unless you created a database of names yourself for it to autocomplete when you type them. But I haven't seen anything like that, personally.
