Gmail SMTP Relay Setup not working

Hi Folks,

I’ve installed discourse on an Ubuntu 18.04 by this guide (it’s with Ubuntu 16.04, but I think its quite the same):

Then I setup the email configuration like here discribed:

Note: It dont worked for me to apply just a IP range, only full IP-Address worked.

But I still dont get emails working. When I do the doctor test, it says:

==================== MAIL TEST ====================
SMTP server connection successful.
Sending to . . 
Sending mail failed.
Replacing: Sending mail to

==================== DNS PROBLEM ====================
This server reports NOT FOUND, but reports Discourse 2.4.0.beta2 .
This suggests that you have a DNS problem or that an intermediate proxy is to blame.
If you are using Cloudflare, or a CDN, it may be improperly configured.

I also tried to set “Allowed senders” in the gmail suite to “all”, but that also not helped.

And of curse, if I try to setup the admin account, I just dont get a mail…

Can anybody help me here, cant be possible that thats so hard to setup ^^

Kind regards,

Relaying through Gmail is a violation of their Terms of Service, so we do not support it. We recommend using a service like Mailgun.

Hmm. So maybe you’ve got a reverse proxy? Since

You’re in good shape there.

If you’re paying for Gsuite (and not Gmail) it’s not a violation of their TOS to have Discourse send mail, but it’s still a huge pain and you can’t get much help here. If you have a credit card your life will be much easier if you go with Mailgun (or similar).
