@Simon_Manning @pfaffman – **EDIT: see end of message** Thanks for the responses! I’ve had to be away for a bit, but am digging back into this… > [@Simon\_Manning](#): > > Just to confirm, it sounds like you have these (among the rest) in `app.yml`: > > ```plaintext > DISCOURSE_SMTP_USER_NAME: admin@tasat.org > DISCOURSE_NOTIFICATION_EMAIL: admin@tasat.org > > ``` > > And this in `reply by email address`: > > ```plaintext > replies+%{reply_key}@forum.tasat.org > > ``` > > Is that right? Yes, that’s what I have at the moment. > [@Simon\_Manning](#): > > If so, do email notifications that don’t accept replies still work? I believe the email verification is an example of that, so you could try creating an account and see if that email is sent successfully. When I try creating an account now, the submit button doesn’t do anything. As if it knows it won’t work. (And nothing shows up in Skipped or elsewhere.) > [@Simon\_Manning](#): > > Typically Reply-To is not treated as part of the sender information, it just provides a default To address to use when people reply, but perhaps Hostinger do treat it as such. You might be able to add a sending alias for `replies@forum.tasat.org`. Edit: I have set “[replies@tasat.org](mailto:replies@tasat.org)” as a sending alias for [admin@tasat.org](mailto:admin@tasat.org), and confirmed that it works for sending and receiving. I’ve also confirmed delivery of an email sent from an external client addressed to `replies+verp-174bc7d8411bc4ec2cfa84c55bd31425@forum.tasat.org` In the interest of trying _something_, I changed `reply by email address`: from `replies+%{reply_key}@forum.tasat.org` to `replies+%{reply_key}@tasat.org` But it doesn’t change the results. > [@](#): > > What happens if you try sending a test email to an address you get from [https://www.mail-tester.com/](https://www.mail-tester.com/)? It doesn’t arrive at mail-tester. All outgoing attempts end up under “skipped” with a variety of this message: ```plaintext 553 5.7.1 : Sender address rejected: not owned by user admin@tasat.org ``` Maybe this is interesting..? When I run discourse-doctor, outbound email fails as follows: ```plaintext ==================== MAIL TEST ==================== For a robust test, get an address from http://www.mail-tester.com/ Sending mail to REDACTED . . Testing sending to admin@tasat.org using smtp.titan.email:587, username:admin@tasat.org with plain auth. SMTP server connection successful. Sending to admin@tasat.org. . . Mail was not sent. Reason: 553 5.7.1 : Sender address rejected: not owned by user admin@tasat.org ``` Sending directly to the replies+ address (or a [forum.tasat.org](http://forum.tasat.org) address) from an email client works – it follows the “replies” alias and ends up in the admin inbox. Where is the rejection coming from? I had a look at the article section “Prevent outgoing host email from interfering.” I have no path /etc/postfix – but here’s my netstat output: ```plaintext root@forum:/var/discourse# netstat -tulpn | grep :25 tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 1487576/docker-prox tcp6 0 0 :::25 :::* LISTEN 1487581/docker-prox ``` **MAJOR EDIT –** I heard back from Titan support tonight: _“The reply-to address and from address should be the same or else the email won’t go through.”_ So I guess all the troubleshooting is out the window and I have to look for a new email host that doesn’t impose that requirement. --- _[View the full topic](https://meta.discourse.org/t/set-up-mail-receiver-but-now-site-wont-send-any-emails/283817)._
