Recently had this issue. Here’s what fixed it: > [@Troubleshoot email on a new Discourse install](https://meta.discourse.org/t/troubleshoot-email-on-a-new-discourse-install/16326/2): > > ## Is the email domain correct? > > The default email from address is based on the install domain plus subdomain, so if your URL is `discourse.example.com` it will be: > > `noreply@discourse.example.com` > > But if your mail provider is expecting: > > `noreply@example.com` > > … you may have problems! To get around this, edit and uncomment this line in `app.yml` > > ```plaintext > ## If you want to set the 'From' email address for your first registration, uncomment and change: > #- exec: rails r "SiteSetting.notification_email='noreply@example.com'" > ## After getting the first signup email, re-comment the line. It only needs to run once. > > ``` > > You’ll need to issue a rebuild after uncommenting the above line and setting the from email address as required. > > You can also change this from the command line, if needed: > > ```plaintext > ./launcher enter app > rails r "SiteSetting.notification_email = 'discourse@yoursite.com'" > exit > > ``` --- _[View the full topic](https://meta.discourse.org/t/trying-to-validate-with-mailjet-needs-txt-file-or-dns-entry/138508)._
