I've installed PostFix on an Ubuntu droplet. Now how can I connect a backend ( Node, PHP, Python, etc ) ?
I’ve followed the Postfix , Ubuntu tutorial for setting up Postfix as a send only SMTP server on a droplet. The implementation of Postfix works fine and passed the tests found on the tutorial. Now how can I connect a backend like Node.js to Postfix so I can collect form submitted data and email them through Postfix? Thank you.
