Gmail sends email with wrong name

Question

I just set up an email account on G-Suite and its like that:

Name: MyDomain.com
Email: [email protected]

However when I send email from this email account it is displayed as:

Name: AnotherDomain.com

I don't have this domain on G-Suite a long time ago and don't know why it fetches this wrong name from it. Any ideas?

I tried adding an SPF record, but it doesn't solve the problem:

"v=spf1 include:_spf.google.com ~all"

Answer 1

The username must be a valid account in your domain. Read more at G-Suite APIs Gmail Users Settings.

• Sign in to the Google Admin console.

• From the dashboard, click Apps.

• Click G Suite > Gmail > User settings.

• In the Catch-all address section, select the Forward the mail to: option.

• Enter the username for the catch-all address. The username must be a valid account in your domain. Don’t include the domain name, @your-domain. It’s automatically added to the address.

• At the bottom, click Save.

If you want to bounce messages addressed to nonexistent recipients:

• Sign in to the Google Admin console.

• From the dashboard, click Apps.

• Click G Suite > Gmail > User settings.

• In the Catch-all address section, select the Discard option.

• At the bottom, click Save.
