To get Gmail to recognize the Reply Address as the sender and to recognize the Reply-to in the header, you will have to create an alias.

To do this:

  1. Open Gmail.

  2. Click on Settings (Gear icon).

  3. Click on Accounts, or Accounts and Import.

  4. Next to Send mail as, click on Add another email address you own.

  1. Enter a name and the reply email address you want to see appear; i.e.,, and click Next Step to complete the process.

  1. After completion, you should see both the main and alias email address.

Verifying success

Sending an e-mail will now show the correct sender (reply-to) information in the recipient's inbox.

Logging into your account using the main-authenticating account (gmailacctUID) now allows you to send e-mails using the alternate (alias) email address.
