Hello 

 

epending on the type of hosting account you are using that will dictate the relay server address you will want to configure your application to use, here are the list of examples.

The 421 error can be fixed by increasing the value of ‘smtp_accept_max’ setting in exim configuration file. But simply increasing this limit is not a healthy action.
