In this article you will learn how to setup your Gmail account to 'Send Mail As' using another email address. This is helpful if you use Gmail for your primary mail account using a personal email address such as myname@gmail.com but you want to be able to receive email from and reply from another email account such as myname@mydomain.com.
Before beginning this guide it is often desired/needed to have mail from myname@mydomain.com forward to myname@gmail.com. If you do not already have a forward setup in your account please setup your mail forwarding so that you can receive your domain emails at your gmail address.

1) Login to your gmail account.
2) Go to https://www.google.com/settings/security/lesssecureapps and Turn On this feature.
3) Go to https://accounts.google.com/DisplayUnlockCaptcha and click Continue.
