Problem

You see the following error while attempting to send email:

Sender Verify Failed

Cause

This error indicates that the sending email address does not exist on the SMTP server.

To confirm this on a cPanel & WHM server:

  1. Log in to cPanel and navigate to Home » Email » Email Accounts.
  2. Note the email accounts on this page.
  3. In WHMCS, go to the General tab at Configuration () > System Settings > General Settings.
  4. Verify that Email Address matches one of the email addresses that you saw in cPanel.

Solution

Make certain that the email address in the General tab at Configuration () > System Settings > General Settings matches an email account on the SMTP server.
