Title: Plugin stopped working Last modified: January 12, 2021 --- # Plugin stopped working * Resolved [alexaptdigital](https://wordpress.org/support/users/alexaptdigital/) * (@alexaptdigital) * [5 years, 4 months ago](https://wordpress.org/support/topic/plugin-stopped-working-204/) * Our Post SMTP plugin mysteriously stopped working right around the time that we changed hosting. We’re having trouble diagnosing the issue ourselves and are hoping that we could get some assistance. Plain english explanations/instructions are greatly appreciated! * Here’s a video that described the issue, as far as I’m capable of seeing: [https://share.getcloudapp.com/P8umP7JK](https://share.getcloudapp.com/P8umP7JK) * Here is the github page referenced in my video: [https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting](https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting) * Here is the results of the diagnostic test: Mailer: phpmailer HostName: fresnel- prism.com cURL Version: 7.58.0 OpenSSL Version: OpenSSL/1.1.1 OS: Linux pod-157042 5.4.0-1028-gcp #29~18.04.1-Ubuntu SMP Mon Oct 5 16:41:43 UTC 2020 x86_64 PHP: Linux 7.4.13 C PHP Dependencies: iconv=Yes, spl_autoload=Yes, openssl=Yes, sockets =Yes, allow_url_fopen=Yes, mcrypt=No, zlib_encode=Yes WordPress: 5.6 en_US UTF- 8 WordPress Theme: Storefront Child WordPress Plugins: ManageWP – Worker, Advanced Custom Fields PRO, Async JavaScript, Better Search Replace, WordPress Backup & Security Plugin – BlogVault, Classic Editor, Contact Form 7, Custom Related Products for WooCommerce, Google Tag Manager for WordPress, Facebook for WooCommerce, Flamingo, iThemes Security Pro, Jetpack by WordPress.com, Mailchimp for WooCommerce, New User Approve, Post SMTP, Redirection, Advanced Editor Tools (previously TinyMCE Advanced), WooCommerce UPS Shipping Plugin with Print Label, User Role Editor, Video User Manuals, WooCommerce Reviews Manually Approved, WooCommerce Composite Products, WooCommerce Dynamic Pricing, WooCommerce Authorize.Net Gateway, WooCommerce Print Invoices/Packing Lists, WooCommerce USPS Shipping, WooCommerce, WordPress Importer, Yoast SEO, WP Product Feed Manager, WP Sitemap Page, WPMU DEV Dashboard WordPress wp_mail Owner: /nas/content/live/stagingfresnel/wp-includes/pluggable. php WordPress wp_mail Filter(s): wp_staticize_emoji_for_email, PostsmtpMailer- >get_mail_args WordPress phpmailer_init Action(s): wpcf7_phpmailer_init, my_phpmailer_example, PostsmtpMailer->phpmailer_smtp_init Postman: 2.0.16 Postman Sender Domain (Envelope |Message): fresnel-prism.com | fresnel-prism.com Postman Prevent Message Sender Override (Email|Name): No | No Postman Active Transport: SMTP (smtp:none:plain:// localhost:587) Postman Active Transport Status (Ready|Connected): Yes | No Postman Deliveries (Success|Fail): 718 | 75 Viewing 4 replies - 1 through 4 (of 4 total) * [Tim](https://wordpress.org/support/users/tneville/) * (@tneville) * [5 years, 4 months ago](https://wordpress.org/support/topic/plugin-stopped-working-204/#post-13899880) * Hi Alex, * Looks like your hosting with WPEngine? As far as I’m aware, they don’t have any kind of SMTP facility available. You’d need to send your messages through another SMTP provider. * Looking at your MX records, GoDaddy seem to be your mail provider, so perhaps you can set up an SMTP account there and point to that? * Does that help? * Kind Regards, Tim * Thread Starter [alexaptdigital](https://wordpress.org/support/users/alexaptdigital/) * (@alexaptdigital) * [5 years, 4 months ago](https://wordpress.org/support/topic/plugin-stopped-working-204/#post-13900290) * > Looking at your MX records, GoDaddy seem to be your mail provider, so perhaps > you can set up an SMTP account there and point to that? * Do you have any instructions? We have an IT company that manages this sort of thing, but they’re asking us what we need them to do… * [Tim](https://wordpress.org/support/users/tneville/) * (@tneville) * [5 years, 4 months ago](https://wordpress.org/support/topic/plugin-stopped-working-204/#post-13901014) * Hi Alex, * You need to create a mail account on your GoDaddy hosting, and then connect in with that. Check the GoDaddy documentation for the SMTP server, but if you are based in America, the outgoing mail server should be: `smtpout.secureserver.net` * Your `localhost` setting for the SMTP server is the problem here. Hope this helps. 🙂 * Kind Regards, Tim * Thread Starter [alexaptdigital](https://wordpress.org/support/users/alexaptdigital/) * (@alexaptdigital) * [5 years, 4 months ago](https://wordpress.org/support/topic/plugin-stopped-working-204/#post-13904252) * This issue has been resolved. * We needed to re-configure the plugin and use the Office 365 smtp details described in this article (option #1): [https://docs.microsoft.com/en-us/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-microsoft-365-or-office-365](https://docs.microsoft.com/en-us/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-microsoft-365-or-office-365) Viewing 4 replies - 1 through 4 (of 4 total) The topic ‘Plugin stopped working’ is closed to new replies. * ![](https://ps.w.org/post-smtp/assets/icon-128x128.gif?rev=3209655) * [Post SMTP – Complete Email Deliverability and SMTP Solution with Email Logs, Alerts, Backup SMTP & Mobile App](https://wordpress.org/plugins/post-smtp/) * [Frequently Asked Questions](https://wordpress.org/plugins/post-smtp/#faq) * [Support Threads](https://wordpress.org/support/plugin/post-smtp/) * [Active Topics](https://wordpress.org/support/plugin/post-smtp/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/post-smtp/unresolved/) * [Reviews](https://wordpress.org/support/plugin/post-smtp/reviews/) * 4 replies * 2 participants * Last reply from: [alexaptdigital](https://wordpress.org/support/users/alexaptdigital/) * Last activity: [5 years, 4 months ago](https://wordpress.org/support/topic/plugin-stopped-working-204/#post-13904252) * Status: resolved
