Setting Up Thunderbird to Send Email From a Different Address

Certain staff members occasionally need to send mail which appears to come from another email address. There are two basic reasons one may wish to do this:

  1. You would like to send email as a different individual but would like the recipient to reply to you.
  2. You would like to send email from a group mail alias and would like the recipient to reply to that alias.

Please note that you are required to obtain permission before sending mail as another person.

Create and Configure Account or Identity

Thunderbird 16 and later

  1. From your main Thunderbird account, pull down your "Tools" menu and select "Account Settings."
    If your menu options are missing, right-click on the blue bar at the top of the window and select "Menu bar."
  2. In the right-side pane of the "Account Settings" window, click the "Manage Identities" button on the bottom right.
  3. Click the "Add" button.
  4. Press the various tabs of the "Identity Settings" window and configure the account as you wish. If you would like to receive the replies to any messages you send from this identity, be sure to put your full email address in the "Reply-to Address" field under the "Settings" tab.
  5. Click "OK" then "Close" then "OK."

Send a Test Message

Back in your main Thunderbird window:

  • Click on your Write icon to create a new message.
  • Pull down the drop-down menu next to the From: field and select the new account that you just created.
  • In the To: field type your own email address or the address of a coworker involved in the project. Put the word Test in the Subject: field and in the body of the message. Press Send
  • Look in your Sent mailbox for the message to verify that everything is correct.
