Problems using mailgun to send mail? about docker-zulip HOT 7 CLOSED

@njuaplusplus have you set the following env vars in the docker-compose.yml?

• ZULIP_SETTINGS_EMAIL_HOST (email host, for example smtp.example.com)
• ZULIP_SETTINGS_EMAIL_HOST_USER (email host username)
• ZULIP_SECRETS_email_password (password of the email host user)

@galexrt
Yes, I have set these vars.

And I'm sure that the user and password are correct.

Some hosting providers block outgoing traffic to SMTP ports, have you checked to make sure you can telnet from your server to mailgun on port 25?
telnet mg.yourdomain.com 25
You should see some header like:
220 yourdomain.com ESMTP Postfix

@njuaplusplus If you can connect to the smtp server using telnet like @pirate said.
You can copy the logs out of the container using the docker cp command and see if you spot any errors.

This would copy the /var/log folder out of the container, docker cp docker_zulip_zulip_1:/var/log zulip_log.

@njuaplusplus I just tested it using my own mailgun account and it worked without a problem.

As I wrote, copy the /var/log folder out of the container and check the logs if there are any errors.

Closing this, because it seems to be a server host/network problem.

@pirate
Thank you.
The problem I met is because the first user is not created.
So when I use the forget password to find the password of the first user,
the mailgun of course will not send the email.

@njuaplusplus See #25. I fixed the user creation script in the latest dev version.
I will merge it soon with the latest version.
