A user is experiencing issues with email setup on their Discourse forum using Mailgun. Despite DNS settings showing “active” and “verified”, they are not receiving emails for their admin account.
The user ran ./discourse-doctor and provided the output DiscourseUser. Benjamin_D suggested checking for port issues and provided a troubleshooting guide. However, the user has tried the suggested solutions and remains stuck.
The user is hosting their forum on DigitalOcean using the Discourse 1-click app DiscourseUser. Benjamin_D provided shell commands to test authentication with Mailgun, but the user is not familiar with coding and is unsure where to execute the commands.
Bernjamin_D and crcoli7307 suggested that the 1-click app may not be supported and may be causing issues. However, the user has successfully used the 1-click app in the past and is hesitant to perform a manual install DiscourseUser.
Bernjamin_D recommends trying to troubleshoot the issue with the shell commands and finding the missing configuration on the host system. pfaffman also provided a link to the email troubleshooting guide.
Hello, I’ve been trying to set up my Discourse forum, everything is fine except that I won’t get any mail for the admin account when trying to set it up.
I use mailgun, and everything is fine on that end in the DNS settings, with it showing “active” or “verified” in green colors on all the settings.
Checking the logs on mailgun it doesn’t show anything either.
I ran ./discourse-doctor and this is what it shows:
Does anyone know what I can do?
Hi,
you’ll find some useful hint here: Troubleshoot email on a new Discourse install
Some port issue maybe are-your-smtp-connections-being-blocked-4 ?
I’ve tried solutions there and I’m kinda stuck, I even did a rebuild to make sure I didnt spell anything wrong, but I copy pasted everything during my setup to make sure I wouldn’t misspell anything.
This is the message I get when checking the port:
Are you attempting to hosting this forum in the cloud, if so, which provider are you using? They may be blocking the requests.
I’m hosting it on digitalocean with the discourse 1 click app.
could you try to authenticate
create a base64 encoded string
echo -ne '\0username\0password' | base64
then
openssl s_client -connect smtp.mailgun.com:587 -starttls smtp
and
AUTH PLAIN withthebase64stringfromabove
I take that back. It did initialize a connection to mailgun.
Where do I do this? I’m sorry I’m not a coder, just literally followed this youtube tutorial lol.
oh…
I see, I mean I’ve done it before successfully with the “1 click app” 2 years ago for another forum, and the only thing that I have trouble with right now is the email not going through 
seems rather excessive to do it the hard way which I probably can’t anyways with this minor issue
Sorry I pasted the wrong youtube video, I updated previous post but this is the one:
Ah yes, I understand the dilemma, but I’ve found the exercise quite rewarding down the road and on the other hand it’s very difficult if not impossible to follow every customization done in these 1’click installs so support is very difficult.
But you can try to see what’s wrong with the shell commands above in a terminal and find out what is missing from the host system.
