The BoldGrid Backup plugin works with email notifications that work either with phpMail with no authentication or using an SMTP mail plugin using authentication. Due to heightened security practices, the phpMail option is often blocked. So, if you are using the BoldGrid Backup plugin, it is recommended that you use SMTP authentication to make sure that your notifications are being received.
Information on the Email used by the BoldGrid Backup
The BoldGrid Backup plugin uses the following format for its notification emails:
`$headers = 'From: ' . $site_title . '<' . $admin_email . '>' . "\r\n" . 'X-Mailer: PHP/' . phpversion() . "\r\n";
$status = wp_mail( $admin_email, $subject, $body, $headers );`
The email notification does pass the admin email as the “From” address.
Recommendation for BoldGrid Backup Notifications
Though the phpMail option for sending notifications does work, it unfortunately was made before security issues were as much of a concern as they are at this time. Most mail servers now require SMTP authentication in order for mail to be properly delivered. Here are a few plugins that you can apply to WordPress in order to use SMTP authentication:
You now have enough information to help prevent your BoldGrid Backup notifications from being blocked due to lack of authentication.
