Frequently Asked Questions

Common questions about WebDig.DEV SMTP

Messages sent through WordPress wp_mail() use this plugin's SMTP transport, including standard form notifications. API-based delivery, direct mail() calls and independent PHPMailer instances may bypass WordPress mail hooks. Avoid running competing SMTP plugins.

Look for X-WebDig-SMTP and X-WebDig-Delivery-ID in the received message source. Match the Delivery ID with the local log. These diagnostic headers contain no credentials; a receiving mail service may remove them.

No. WebDig.DEV SMTP does not require a WebDig.DEV remote setup service. SMTP credentials are stored in your WordPress installation and used for email delivery from that installation.

If Backup SMTP is enabled and the error is eligible for failover, the plugin attempts delivery through the Backup SMTP transport. If delivery still cannot be completed and the local queue is enabled, the message can be queued for a later retry.

Yes. Authentication-failure failover can be enabled or disabled in the plugin settings.

No. The health panels are diagnostic aids. DNS and transport configurations vary between providers. The definitive result for message authentication should be checked in the headers of a message received through the configured transport.

No tracking is added by WebDig.DEV SMTP.

Nothing changes. WordPress keeps using its default email delivery and an admin notice reminds you to configure the plugin. Once a Primary (or enabled Backup) SMTP host is saved, WebDig.DEV SMTP handles delivery and never silently falls back to PHP mail().

Yes. Define WEBDIG_SMTP_PRIMARY_PASSWORD and/or WEBDIG_SMTP_BACKUP_PASSWORD in wp-config.php. A defined constant overrides the stored password and the password field becomes read-only.

Yes. Primary and Backup are independent SMTP configurations, provided each transport is authorized to send mail for the addresses and domains you configure.
