“Force From Email” not working with some plugins

Hi @dberdal,

Thanks for reaching out. I’ve tested the ‘Force From Email’ option with WooCommerce emails and the From Email is as expected. If you have a different “From” address in WooCommerce(or other plugins) than the one in WP Mail SMTP and ‘Force From Email’ is enabled, the email in the “From” address field of WooCommerce (or other plugins) will be added to the reply-to header while the From Email should still be the one used in WP Mail SMTP.

The From Email might have been forced from elsewhere. If possible, could you please share the screenshot of the WooCommerce Emails section, WP Mail SMTP section, and the original message of the email?

Thanks!

Hi Sanjeev,

Thank you for following up –

I am using wordpress multisite and using the wp-config.php defines to set the SMTP email defaults. The correct settings show in the SMTP email UI, and they are correctly being used by WordPress and Wordfence…

I did find the following error in my WordPress Debug… not sure if it’s at all related
PHP Warning: A non-numeric value encountered in /home/wordpress/wellcoachedmarketing/public_html/wp-content/plugins/wp-mail-smtp/src/Processor.php on line 215

Let me know if there is anything else I can send

Hi @dberdal,

Thanks for the details with screenshots. It looks like you’ve used the value of constant for Force From Email incorrectly. The PHP warning probably indicates that the string value is used. Please make sure, you’re using:

define( 'WPMS_MAIL_FROM_FORCE', true );

and not,

define( 'WPMS_MAIL_FROM_FORCE', 'true' );

Also, make sure you’re using the constants above the line that reads:

/* That's all, stop editing! Happy publishing. */

I hope this helps!

Oh man thank you! I should have noticed that. Removing quotes from the true and false defines solved that. I thought they were copy pasted from a previous working setup.

For any future people wondering, here are the working defines. I have a few commented out that I am not currently using

define('WPMS_ON', true);
//define( 'WPMS_DO_NOT_SEND', true );
define('WPMS_MAILER', 'smtp' );
define('WPMS_SMTP_PASS', '**********');
define('WPMS_SMTP_USER', 'postmaster@mail.**********.com');
define('WPMS_SMTP_HOST', 'smtp.mailgun.org');
define('WPMS_SMTP_PORT', '587');
define('WPMS_SMTP_AUTH', true);
define('WPMS_MAIL_FROM', 'noreply@*****');
define('WPMS_SET_RETURN_PATH', false); // Sets $phpmailer->Sender if true
define('WPMS_SSL', 'tls'); // Possible values '', 'ssl', 'tls' - note TLS is not STARTTLS
//define('WPMS_MAIL_FROM_NAME', 'My WordPress Multisite');
define('WPMS_MAIL_FROM_FORCE', true); //force all sites to use sending address defined above

Thanks for the helpful support!
