No mail send with a Mailjet config on VPS

Hi.

First of all. Thanks very much for this great product :smile:

I try to configure a new Discourse instance on my OVH VPS in order to send mail with mailjet (or mandrill) but no mail send. I tried many things without success.

Any idea? Where can I find logs?

My config below:

env:
  ## TODO: List of comma delimited emails that will be made admin and developer
  ## on initial signup example 'user1@example.com,user2@example.com'
  DISCOURSE_DEVELOPER_EMAILS: "bmxperience@gmail.com"

  ## TODO: The domain name this Discourse instance will respond to
  DISCOURSE_HOSTNAME: "discourse.bmxperience.com"

  ## TODO: The mailserver this Discourse instance will use
  DISCOURSE_SMTP_ADDRESS: "in-v3.mailjet.com" # (mandatory)
  DISCOURSE_SMTP_PORT: 587 # (optional)
  DISCOURSE_SMTP_USER_NAME: "my-mailjet-api-key" # (optional)
  DISCOURSE_SMTP_PASSWORD: "my-mailjet-secret-key" # (optional, WARNING the char '#' in pw can cause problems!)
  #DISCOURSE_SMTP_ENABLE_START_TLS: true # (optional, default true)
.
.
.
run:
  - exec: echo "Beginning of custom commands"

  ## If you want to set the 'From' email address for your first registration, uncomment and change:
  - exec: rails r "SiteSetting.notification_email='forum@bmxperience.com'"
  ## After getting the first signup email, re-comment the line. It only needs to run once.

I successfully send mail using telnet:

I’m not to familiar with mail jet as I use Send Grid with my discourse instance but that shouldn’t matter.

  • if you force an email to be sent from discourse (sign up a test user etc) and when you check on yor mail jet dashboard, do any outbound emails show. If so are they being “dropped” ?

  • have you verified your SMTP settings on yourdiscourse/admin/email ?

Did you try disabling TLS in the config? That would be a difference between your settings and the telnet test.

Good point! I changed this line:

DISCOURSE_SMTP_ENABLE_START_TLS: false # (optional, default true)

and
 it works!

Thanks very much.
