Hi,
I try to instal Discourse on my server as Docker container. Everything is fine until sending email on the first run.
I didn’t receive mail.
I run discourse-doctor and this is the result (I’ve changed domain to MY\_DOMAIN):
```

This server reports NOT FOUND, but forum.MY_DOMAIN reports Discourse 2.3.0.beta6 .
This suggests that you have a DNS problem or that an intermediate proxy is to blame.

I’ve tested manually by [mail-tester.com](http://mail-tester.com) . [mail-tester.com](http://mail-tester.com) result is: 8.9/10
I have small issue with
> SpamAssassin: -1.1
Anyway I can send and receive mail on this address.
How can I resolve this problem? ☹

That message is coming from the SMTP server. It is not accepting mail from your Discourse server.

Whoever is in charge of `mail.MY_DOMAIN` is who you need to talk to. If it’s you, then you need to check your logs and google “554 blacklisted your-mail-server-software”

I use server mail as [poste.io](http://poste.io) . It’s dockerized mail server and I host on the same server.
I’ve checked another server (also dockerized by [poste.io](http://poste.io) ) and I’ve got `500 Unrecognized command` .
Maybe someone configured Discourse with poste. io ?

Is there a reason you’re not using one on the [recommended free providers](https://github.com/discourse/discourse/blob/master/docs/INSTALL-email.md)?

Maybe so. You should ask people who know about poste. io and see what they have to say.

I checked elasticmail. But still doesn’t work. I used settings from @Stephen post and set admin account as one on my gmail account.
All settings are ok, becuse when I run `discource-doctor` I’ve got `SMTP server connection successful` and `Mail accepted by SMTP server`.
I’ve checked inbox, spam folder - no mail.
Elasticmail says `Today email sent: 0` .
Discource base is in `2.0.20190321-0122` version .

It’s hard to explain how `discourse-doctor` would report that the mail sent successfully and that Elasticmail would not have the message in the logs. The only explanation I can imagine is that the ElasticMail credentials that you used are not for the same account that you’re checking the logs of. That seems wildly improbable.

I’ve checked twice. Everything is ok. It is very weird 😔
I’ve tried different mail as administrator - still doesn’t work.
