Mailgun rejects logins

Also, I have opened mailgun support ticket and they provided, this - The only information we have on Exim is the below snippet from our docs. As the link mentioned, you will need to configure a smart host. For more information outside of the below, please see Exim"s documentation for authenticated outgoing SMTP.

  # In your exim.conf:
    # In routes configuration:
    mailgun:
     driver = manualroute
     domains = ! +local_domains
     transport = mailgun_transport
     route_list = * smtp.mailgun.org byname
    # In transports configuration:
     mailgun_transport:
     driver=smtp
     hosts_try_auth = smtp.mailgun.org

Also make sure to configure login credentials (in your /etc/exim/passwd.client): *.mailgun.org:username:password

Based on what you're providing it appears to connect to mailgun without issue, right up until authentication when it fails with the following:

  mailgun_login authenticator failed H=smtp.mailgun.org [52.45.160.225] 535 5.7.0 Mailgun is not loving your login or password

Furthermore, if the instructions in the resource were followed you should have matching entries to what mailgun sent you added to your exim configuration. With a couple of exceptions: They note:

     hosts_try_auth = smtp.mailgun.org

where our resource which was tested in May notes:

hosts = smtp.mailgun.org
hosts_require_auth = smtp.mailgun.org
hosts_require_tls = smtp.mailgun.org

We also don't recommend putting the user/password in the same location - instead this should go in the AUTH section as noted in the example. Can you show me what you have in /etc/exim.conf.local currently and what the output when you attempt to connect to mailgun is per the exim logs at /var/log/exim_mainlog
as well as confirm the username:password are correct for mailgun

Thank you for the response! I was writing a reply with my Exim config and log and while doing it, I figured it out. So basically, in Mailgun I went to domains -> my domain -> SMTP and there were proper credentials with a different SMTP server. I have tried them before, but it didn't work, because I haven't changed the SMTP servers. So after changing everything, my Exim config looks like this.

%RETRYBLOCK%
+secondarymx                    *                               F,4h,5m; G,16h,1h,1.5; F,4d,8h
*                               *                               F,2h,15m; G,16h,1h,1.5; F,4d,8h

It would be awesome if you could amend the

Hello, It looks like you still have the hide client_send in the config - was it removed? I can definitely update the tutorial to reflect that the domain needs to be verified and you'll have to log in to the dashboard to get your SMTP Credentials though. Thanks for that!

Hi, This is the exim.config.local that works. What mailgun sent, it couldn't even contact their server (I was getting timed out error) Thank you!
