Email Not Sending Due to SMTP Issues
Critical_DevX is experiencing issues with email not sending after installing Discourse, despite having correct SMTP details. They used a Mailgun account with a sandbox domain, but still didn’t receive emails.
Jo-andre suggested running ./discourse-doctor and reading the troubleshooting guide, but Critical_DevX had already tried these steps. Jo-andre then suggested checking other topics related to Mailgun issues.
Critical_DevX shared a screenshot of their settings and asked if it’s possible to bypass email verification for installation completion. Jo-andre replied that it’s not possible.
Critical_DevX mentioned that they didn’t verify their Mailgun account with a credit card, and Jo-andre suggested that DNS propagation might still be in progress.
Critical_DevX shared an error message from Discourse Doctor and Stephen pointed out a typo in the SMTP server address.
Pfaffman explained that the sandbox domain has limitations and Critical_DevX asked how to configure it to send emails only to themselves.
After trying to configure the sandbox domain, Critical_DevX still couldn’t send emails and pfaffman suggested checking the Mailgun logs for errors.
Critical_DevX asked how to check the logs and Canapin provided a straightforward explanation. Critical_DevX shared a screenshot of the logs, and hosch asked if the time period for displaying logs is correct.
Hi! I just installed Discourse and my STMP Details are correct but I still do not get emails I reran everything.
My details were:
Admin: devxorwhatever@gmail.com
Then I used a mailgun account for the rest it was like
postmaster@sandbox79c1c2ead8b24728813d3f8584nfad3b1.mailgun.org
^ This is a fake
But I still do not recive any mail..
I was wondering if anyone could help?
Have you tried ./discourse-doctor
Also you should read this.
Yes I have and I did read it but it did not work.
Have you gone trough other topics like this one?
No. am not a 100% sure tho.
I’ve been trough the installation at least 50 times.
If you follow the official installation guide it should work. could be a miss typo and in a lot of my cases a fresh install and make sure all DNSs are correct should do trick.
They are I copied all the details from mailgun its self its worth to mention I did not do verification with a credit card
If the domain is new today the DNS propagation might still be in progress. That could take up to 72 hours but often less.
If not you should wait for someone with proper skills to help you out. 
Also my server is a very secure one and discourse doctor says
sudo: unable to resolve host vps.redacted.tk: Name or service not known
Timeout to open TCP connection to stmp.mailgun.org:587 (exceeds 5 seconds)
Thats another error
It should be smtp.mailgun.org not stmp - I’ve corrected your title!
If it’s the sandbox then you need to do what’s required to configure it. The sandbox will be able to send only to you, and then you’ll need to do this all over again when you want to have a forum that other people can use.
Alright how do I configure it to send only to me?
Ok so I added my email and stuff but it still won’t send
You can check your logs at mailgun. If you’re not getting a bad password error then you’re likely sending from an address that mailgun is not configured for. You need to set the NOTIFICATION_EMAIL to whatever you configured mailgun for.
Alright will try Tommorow and will let you know the resaults
