[Error] : Message delivery failed - Name or service not known

[prudhomm...@gmail.com]

Hi,

I just installed Canvas LMS with production start guide. Can works fine and it's a pleasure. But ougtgoing mails are not working and I don't know why. I try to use different "outgoing mail configuration" but I have all time the same error called : " Message delivery failed".

Anyone can tell me more about this error ?

Best regards.

Clément,

It looks like the address in your outgoing_mail.ml is not resolving.

Hi Cody,

Thanks for your answer. In my "outgoing_mail.yml" file, I have :

production :
  address: "smtp.gmail.com"
  port: "587"
  user_name: "m...@email.fr"
  password: "mypassword"
  authentication: "plain" # plain, login, or cram_md5
  domain: "mydomain"
  outgoing_address: "m...@email.fr"
  default_name: "Instructure Canvas"


So, I'm not sure to understand what I made bad.

Regards.

Clément

Clément,

Two things: it looks like you have a space after "production" and before it's :. That might be the problem. The other thing to check is that you can actually resolve smtp.gmail.com from that server (either ping or the host command should help out here).

Hi Cody,

Thank you !
It was the "space" after production. Everything is ok now.

Best regards.
