Problem #

You see the following error while sending email or importing support ticket replies:

Sender Verify Failed

Cause #

This error indicates that the sending email address is invalid or 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 affected email setting matches an email account on the SMTP server:

• For system mail, check the email address in the General tab at Configuration () > System Settings > General Settings.
• For support ticket email reply importing, check the From Address setting in the Mail tab at Configuration () > System Settings > General Settings.
