Setting up a catch-all server usually involves configuring your domain's email settings through your hosting provider or email service provider. Here are the general steps:
1. Access Your Email Settings: Log in to your hosting provider or email service provider. 2. Locate Catch-All Settings: Find the catch-all or default address settings in your email management panel. 3. Set Up the Default Email Address: Choose or create an email address where all unmatched emails will be forwarded. 4. Save and Test: Save your settings and test by sending emails to non-existent addresses within your domain to ensure they are captured correctly.
