Gmail has made a small change that has a big benefit for those who use email forwarding and have their email forwarded to a Gmail account. Under Settings > Accounts, you may send mail from another email account. Gmail has had a similar feature for some time, but it actually still used their outgoing mail server and showed “on behalf of” message in the from section of the email for users of Microsoft Outlook. Now you may use your own SMTP (outgoing) mail server and send mail without the “on behalf of” note being displayed to your recipients. Learn more about email forwarding.
