@julian Yes. i put in the email address . not the username, ,i don't know what wrong with it..ps :I installed the nodebb on a fresh linode server.

hi , all , i got a new problem, that if register a new account, the mailgun will sent a mail to the new user email address , if i want retrieve the password for an exsited user , the nodebb will occur an error, tells me that error.invalid email .

@julian said:

Hey @xenofilodotcom -- you won't need Postfix if you use the Mailgun plugin. Just plug in your API key and secret (or whatever it needs of you), save, restart your NodeBB, and you should be good to go!

wow. thx so much for you quick reply , this is awesome! i have become your fan now!!

hey. all . i have installed the mailgun plugin ,and got the mailgun service , do i still need the postfix to integrate to communicate with mailgun service?

well. thx so much for all reply, the nginx .conf works for me. and i found you should put 0.0.0.0 before the port 80. so it would look like

server {
listen 0.0.0.0:80;

server_name forum.example.org;

location / {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-NginX-Proxy true;

    proxy_pass http://127.0.0.1:4567/;
    proxy_redirect off;

    # Socket.IO Support
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

}
