Mail and multiple accounts in Gmail I Have a gmail account configured to receive and send emails of a live mail account and I have some services that I need to send emails as live mail to be identified, but in Apple Mail I'm only able to send using the gmail account.

What I need is, using Apple Mail, send emails on behalf live mail account without having to setup the account 'cause I already receive the emails through the gmail account.

Is this possible?
Open accounts tab in preferences
Open any mail account you have
Drop down "Outgoing Mail Server (SMTP)"
Select existing account or select "Edit SMTP Server List" to create and/or modify some.
