Mail server setup

My discourse (new forum) can’t send email for register admin account.
i don’t see error on mail.log
Any help, please?

I recommend starting here:


thanks Arman.
I run discourse-doctor en show this error:

Reason: 553 5.7.1 noreply@xyz: Sender address rejected: not owned by user do-not-reply@zyx

any help, please?

Your SMTP user does not have permission to send email as noreply@xyz

You might want to change the notification email address in app.yml and rebuild or check with your email provider on how to allow sending as other alias.

It seems like you’re using an email provider that doesn’t allow bulk emails so you might want to consider that as well.


Thanks Bhanu.
I install a postfix server on the same server.
I have this error now:

Sending mail to . . 
Testing sending to using server.example:587, username:foro with plain auth.

======================================== ERROR ========================================
                                    UNEXPECTED ERROR

====================================== SOLUTION =======================================
This is not a common error. No recommended solution exists!

any idea, please?

this is the postfix log:

Now is working!

What did you do?

I made a mistake with the e-mail address.
Now, the new forum is on-line!
