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): How to Install Discourse Forum with Nginx on Ubuntu 16.04 Discourse is a free and open source software for creating Internet forum community and mailing list. Discourse forum software has been used by many or... Then I setup the email configuration like here discribed: https://crunchify.com/how-to-setup-email-for-discourse-forum-with-google-apps-smtp-relay-right-way/ 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 info@likamundi-lernen.de. . . Sending mail failed. Replacing: SMTP_PASSWORD Replacing: LETSENCRYPT_ACCOUNT_EMAIL Replacing: DEVELOPER_EMAILS Replacing: DISCOURSE_DB_PASSWORD Replacing: Sending mail to ==================== DNS PROBLEM ==================== This server reports NOT FOUND, but discourse.likamundi.de 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, Zacharias

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

[תמונה] Zacharias_Kreisvorhe: This server reports NOT FOUND, but discourse.likamundi.de reports Discourse 2.4.0.beta2 . 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).

Probably a bit late to help you here, but I can confirm it is possible to use GSuite smtp-relay to send your Discourse emails. The following is a configuration for using the smtp-relay (in Gmail app settings) with no authentication (IP address only). First as you say, you need to configure the app settings to “Only accept mail from the specified IP addresses”, adding the addresses of your Discourse server. The configuration on Discourse side is then – DISCOURSE_SMTP_ADDRESS: smtp-relay.gmail.com DISCOURSE_SMTP_PORT: 587 DISCOURSE_SMTP_USER_NAME: DISCOURSE_SMTP_PASSWORD: They key thing, and what tripped me up for an hour or so, is that you need to specify the username and password vars but leave them blank. Any other values (none, ‘’, etc.) won’t work.

No this does not work. And no shade it is a terrible platform idea to require both domains and mail servers as when you change the DNS on most domain providers their local email server gets messed up. Ive been trying to get this installed for 4 hours now.

Thanks for the workaround! I can confirm it works :slight_smile:
