PMF
-
What does this plugin do?
-
Mesh SMTP routes WordPress email through an SMTP server so your website emails are sent more reliably.
-
Does this plugin work with contact forms and WooCommerce emails?
-
It works with WordPress emails sent through
wp_mail(). This usually includes many contact form plugins, password reset emails, admin notifications, and WooCommerce emails. -
Does this plugin store my SMTP password?
-
Yes, WordPress stores it in the database as part of the plugin settings. The password is not shown back in the UI after saving.
-
Can I lock settings in wp-config.php?
-
Yes. Mesh SMTP supports constants such as
MESHSMTP_HOST,MESHSMTP_PORT,MESHSMTP_USERNAME,MESHSMTP_PASSWORD, and related values. When set, those constants override saved settings and the password value is never displayed in the admin. -
Can I reuse settings on another site?
-
Yes. Mesh SMTP can export the current settings as JSON and import them on another site. For safety, the normal export file does not include the password, so you may need to enter that manually after import.
-
Will this conflict with other SMTP plugins?
-
Only one SMTP plugin should control WordPress email sending at a time. If you are using another SMTP plugin, disable it before enabling Mesh SMTP.
-
Does Mesh SMTP include OAuth setup for Gmail or Microsoft 365?
-
No. Mesh SMTP currently focuses on standard SMTP credential-based setup.
