Override PHP Mail for Mailpoet (via wp_mail)

I must admit, I was surprised to learn that I wasn’t able to log my SMTP traffic using vanilla Mailpoet out of the box. I’ve been using several SMTP plugins over the years, and they are in reality mandatory if you want to ensure predictable delivery of emails sent from the web server, including SSL encryption and authentication. Not to forget logging, which is crucial to debug any delivery issues. I’ve tested Override PHP Mail for Mailpoet with FluentSMTP and so far it works perfectly. All outgoing mail is now being logged and can be monitored within the dashboard. To make sure I have a fallback available, I did the following: first I set up the standard Mailpoet SMTP sending method, including its settings for SMTP host name, port, username, password and SSL, and made sure that worked. then I configured FluentSMTP with the same SMTP settings, and made sure that worked too. finally, I switched Mailpoet send with from SMTP to Your web host / web server (php), and performed a final test, including checking the newsletter was logged in FluentSMTP. It was. That way, should the override fail, I should be able to disable the plugin and toggle Mailpoet back to SMTP and carry on as usual, albeit without the logging. Nice work, and thank you so much for sharing ⭐⭐⭐⭐⭐
