Thank you for your help. I figured it out. I reverted back to the feed from the plugin Google Listings and Ads because that was installed first and worked.

I figured it out. I compared the wp-config.php to a new install wp-config.php and there was an extra entry on the last line – Bolded below. I removed this and it worked fine.

Thanks for your help!

/** Sets up WordPress vars and included files. */
require_once(ABSPATH . ‘wp-settings.php’);
function wp_mail() {}

Hi @sanzeeb3,

Thanks, I still get an error, but here’s my testing:

To test the server, I installed a brand new clean WordPress and only the WP Mail SMTP plugin, nothing else. I used the same Gmail app SMTP and it worked. So the server sends emails.

Then I went back to the problem site and turned off every plugin, deleted all unused themes, removed unused plugins and ONLY kept the WP Mail SMTP plugin active. I retested and it still won’t send.

I checked the wpconfig file and it is clean, nothing in there. I checked all other customize settings and the PHP files themselves. I also deleted other form plugins that may have had a mailer in them. I removed the API to our email marketing service (Mailchimp).

Without removing everything from the site and starting over, do you have any suggestions?

Thanks.

To me it appears the server is blocking sending because the site had a relay hack in the past few months. So the server shut down and sending operations from the site.

I came to this conclusion because the company had the emails blocked from the website on their company Microsoft account. In the past I’ve noticed individual email accounts block or mark as spam bad emails where as server/hosting companies take longer to block a server from sending email (mostly because they are shared for smaller web sites).

We’re changing settings on the server or moving to another hosting platform to fix the issue. If I’m incorrect please feel free to respond.

Thanks.
