User invitation emails not sending

[T_K]

Hi, We are successfully tunning Squidex CMS on a Linux server. We are using Google SMTP settings in appsettings.json, but emails are not sending when we invite a user. Instead we now need to go to Administration and create the user and also a password and send that on to the user.

Is there anywhere else we need to configure to send mail?

regards

TIaan

I don’t think so. No logs or so?

Apologies:

This is from a http request. It cannot be related to your issue. But it seems that your instance cannot communicate with squidex cloud (it reads the newest features from there).

So perhaps your email server is not reachable as well?

[Sebastian]

You can also test the background process:

I tried there. It is by default set to below:

If I start it, it run for a small time and then sets back to the II position

I found this thread, but saw you ended the thread without mentioning where that was

[Sebastian]

Perhaps POP3 vs SMTP or so?

[T_K]

We use SMTP smtp.gmail.com

[Sebastian]

Perhaps a port issue? Sorry, I have no real idea, just thinking about potential issues.

[T_K]

tried 587 as port as well.

“email”: {
“smtp”: {
/*
* The host name to your email server.
/
“server”: “smtp.gmail.com”,
/
* The sender email address.
/
“sender”: "name@domain.com",
/
* The username to authenticate to your email server.
/
“username”: "name@domain.com",
/
* The password to authenticate to your email server.
/
“password”: “********”,
/
* Always use SSL if possible.
*/

    "enableSsl": true,
    /*
     * The port to your email server.
     */
    "port": 587 
  },

Can you confirm that the port entry should not be closed by ,

[Sebastian]

Yes, this should not matter … it is json.

If you want, you can PM me your email details to your server and I can debug it. You could also try 465.

[T_K]

done. I have sent you testing credentials which you can use.
