I have a control panel for game servers called Pterodactyl. I use it in conjunction with mailcow to send emails to users.

My problem is: When performing the SMTP test on the panel, it returns success, and sends the email.

However, when I click on “forgot password” to send an authentication code, the Pterodactyl panel returns that the email was sent, but the email does not reach my gmail.

I need to know how I can check if the Pterodactyl panel is actually sending the email to mailcow, to understand if the problem is with Pterodactyl or mailcow.

How do I monitor this?

    Yes, firstly, I’m using the pterodactyl panel.
    I’m finding it strange, because in the panel itself, in the tab where I can add an email server, I can perform an email sending test. My server’s IP is the one in the screenshot above, when I do the test, and the email is delivered successfully.

    In the image below, there is a tab on the panel, “I forgot my password”, where the user can request a code via email.

    So when it sends the request to mailcow it is not requesting with the IP of the machine, nor of the client, and I do not recognize the IP address that is calling “154.203.197.192”.

    [unknown] Maybe it’s because I’m in Brazil, and the server is in New York.

    The problem is here.

    How can I disable this, to allow all IPs?

      So this IP is your Pterodactyl host? Add the IP to

      System -> Configuration -> Options -> Forwarding Hosts

      What IP address? the 31.220.103.196? Is that all you got in the postfix logs for this IP?
      Seems your connection rate is a bit low. Did you change the default settings?

              Without logs we cannot help.
              Try to figure out what happens in the seconds you click on “forgot password”
              Look at the logs of the panel for exactly that time, then look at the postfix logs in mailcow for exact that time.
