I have a brand new Motorola Razr Maxx running Android 2.3.6.
For my personal email address, I have a vanity domain, and forward email to the vanity domain to my gmail account. I don't like to reveal my gmail account. I want my contacts to have my vanity domain email address in their contact lists, because if I ever switch away from gmail, my public facing email address will remain the same.
On a web browser on a standard home computer, I have my gmail setting configured to "Send mail as:" my vanity domain. That is, if you're in gmail on your home computer web browser, and you click the Settings icon on the upper right, then click the "Accounts and Import" tab, the third setting down, where it says "Send mail as:", I have a second email address configured as the default. This works great!
How do I do the same thing on my Android phone?
