If you have one or more email aliases configured under your mail box, you can use the following procedure to send email from all of your addresses and aliases.
Note: An alias email address is an account in which all email sent to it automatically goes to a master email address. This is not the same thing as having different email addresses that aren't automatically tied to a central address.
- In Mail, choose Preferences from the Mail menu
- Click Accounts
- Select your master account (the one to which email from your alias addresses gets sent)
- Click Account Information and in the Email Address field, add all of the accounts associated alias addresses, each separated by a comma
- Save your changes
Now when you create a new message you can select one of the aliases from the account pop-up menu in the new message window.
