In this article, we will discuss why ‘550 Sender verify failed’ messages occur when you try to send e-mail, and how to resolve the issue.
When you attempt to send the email, there could be a number of causes for the 550 Sender verify failed problem. This error may appear if the sender’s email account does not exist on the Mail exchange or cPanel.
For Ex: If you have added a new add-on domain or you must set up email routing through the remote mail exchanger if you have a parked domain in your cPanel account and its MX records are pointed at a third-party email provider.
To change the remote mail exchanger in cPanel, please follow the instructions listed below:
- Login to your “cPanel account”.
- From the “Search tool”, click on the “Email Routing”.
- Select the “Domain”.
- Tick the “Remote Mail Exchanger” radio button and after that click on “Change”.
That’s it, in this way email will now be sent from the remote mail exchange server on the third-party server configured for email routing.
