How to reject a specific email address in gsuite mail

In G Suite (formerly Google Apps), you can reject specific email addresses using a feature called "Spam filters" or "Email filters". Here are the steps to reject a specific email address:

Method 1: Using Spam filters

1. Log in to your G Suite account and go to the Google Admin console.
2. Click on "Security" and then "Spam filters".
3. Click on "Create a new filter".
4. In the "From" field, enter the email address you want to reject (e.g., [email protected]).
5. Click on "Create filter".
6. In the "Filter actions" section, select "Reject" as the action.
7. Click "Save changes".

Method 2: Using Email filters

1. Log in to your G Suite account and go to the Google Admin console.
2. Click on "Users" and then "Email filters".
3. Click on "Create a new filter".
4. In the "From" field, enter the email address you want to reject (e.g., [email protected]).
5. Click on "Create filter".
6. In the "Filter actions" section, select "Reject" as the action.
7. Click "Save changes".

Note: When you reject an email address using either method, the email will be automatically deleted from the recipient's inbox without being delivered.

Additional tips:

• You can also use wildcards in the "From" field to reject multiple email addresses at once. For example, *@example.com would reject all emails from example.com.
• If you want to reject emails from a specific domain but allow emails from subdomains, you can use the @ symbol followed by the domain name. For example, @example.com would reject all emails from example.com but allow emails from subdomain.example.com.
• You can also use other filter criteria, such as subject, body, or sender's IP address, to create more complex filters.
