How to change the email routing of a domain with the API

Introduction

If you change the mail host of a domain already configured on your cPanel server, you must change the email routing so that mail is sent to the correct server.

Procedure

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
2. Run the following command.

   uapi --user=$username Email set_always_accept domain='$domain.tld' alwaysaccept=$location

   Please note that "$username" must be replaced with the cPanel account's username. While "$domain.tld" must be replaced with the domain that needs the email routing changed. Finally, "$location" must be replaced with "local" if the local mail server will receive mail for the domain or "remote" if it will not.
