Helo command rejected: need fully-qualified hostname about keila

[wmnnd]

The output looks like MAILER_SMTP_PORT is still missing, though.

@wmnnd Thanks! :)
I make a typeo in MAILER_SMTP_PORT. ... after setting it to 587 everything work.

And now I can remove hostname parameter from docker-compose sercive :)

Hey, thanks for reporting this. This is stange … but it seems like it might be a configuration problem on your email server or with your system sender. Did you maybe use the IP instead of the FQDN for your system mailer?

[piotr-sikora-v]

I use "mailcow" ... this is all-in-one docker solution https://github.com/mailcow/mailcow-dockerized, and I use this for many software and there is no problems... also when I configured same settings as "Senders" in Keila and send campaning it works. Only problem is in registration and send password reset.

I use Keila in docker... so I don't configure system mailer.
Maybe I forgot some env?

Here is all my docker env from docker-compose.yaml:

services:
  keila:
    image: pentacent/keila:latest
    depends_on:
      - postgres
    environment:
      SECRET_KEY_BASE: "zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz"
      DB_URL: "postgres://postgres:postgres@postgres/postgres"
      URL_HOST: "xxxxxxxxxxxxxxx"
      URL_SCHEMA: "https"
      MAILER_SMTP_HOST: "poczta.ftdl.pl"
      MAILER_SMTP_USER: "[email protected]"
      MAILER_SMTP_PASSWORD: "xxxxxxxxxxxxxxxx"
      KEILA_USER: "[email protected]"

      DISABLE_REGISTRATION: "false"
      SECRET_KEY_BASE: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
      USER_CONTENT_DIR: "/uploads"

[wmnnd]

Could you try also setting MAILER_SMTP_PORT and MAILER_SMTP_FROM_EMAIL?

I’m afraid I think there is an issue with your server’s DNS configuration then.
One last thing to try and debug if this might be an issue with Keila would be to connect to the Keila console and run the following command:

Connect to the console:
/opt/app/bin/keila remote

Inspect the mailer config:
Application.get_env(:keila, Keila.Mailer)

[piotr-sikora-v]

It can be... but it's docker, so default hostname is random.
I changed now to my reverse IP and I have new error:
