How do I setup SMTP on a Discourse Droplet ?

Just installed the Discourse droplet, changed the root password, and followed the prompts. I was asked for SMTP information and thought it was as simple as using the default, adding my email address, and be done with it. However, emails are not being sent.

Is there another step that I missed?

Configuring and administering a mail server on your own is not always an easy, straight forward task. We have a great tutorial/article about some of the issues you might run into:

If you DO decide you want to run your mail server after reading that article, we have a lot of articles about different options to setup a mail server: Depending on your skill level I would either suggest mail in a box ( for an easier solution or send-only postfix ( for a more advanced solution.



When setting up a web site or application under your own domain, it is likely that you will also want a mail server to handle the domain's incoming and outgoing email. While it is possible to run your own mail server, it is often not the best option for a variety of reasons. This guide will cover many of the reasons that you may not want to run your own mail server, and offer a few alternatives.

I have the same question as the original poster. And, if I may say so, I feel that Andrews does not answer the question.

I am quite happy to have you handle my mail server but at the first SSH sign-in I was asked for my SMTP settings and I think I may have given the wrong port.

How can I change the SMPT port now?

Thank you
