Thank you for contacting WHMCS.
This behavior was occurring because the Storage Settings on the installation were misconfigured.
I have corrected these by manually modifying the tblstorageconfiguration table of the WHMCS database via PHPMyAdmin. After resolving the configuration issue I verified that I was able to send email without issue.
If we can be of further assistance, then please let us know.
Best regards,
