I have a rails mailer that I want to configure with an email account that is non-gmail, and is accessed through outlook. the SMTP address is "smtp.us.exg7.exghost.com". The email is not @exghost.com.

I am running into a 504 5.7.4 unrecognized authentication type error.

Here is my configuration: 

 config.action_mailer.smtp_settings = {

    :address => "smtp.us.exg7.exghost.com",

    :port => "587",

    :domain => "exghost.org",

    :user_name => 'example@example.org', 

    :password => 'Password',

    :authentication => "plain",

    :enable_starttls_auto => true

     }

Does anyone have any insight into this? I have tried various domains- exghost.com, us.exg7.exghost.com, example.org. I have tried changing authentication from "plain" to "login", but nothing seems to change the error.

I know that in gmail you have to allow third-party access, does this need to be done with other formats?

  • I think this question will be of your help: https://stackoverflow.com/questions/6523348/cannot-get-actionmailer-working-with-ms-exchange-via-smtp my guess is that there's an issue with your SMTP server, can you debug which authentication methods does it support? – Carlos Martinez Feb 18 '19 at 19:54
  • It looks like these are the auth methods `smtp.us.exg7.exghost.com` supports `AUTH: GSSAPI NTLM` – Carlos Martinez Feb 18 '19 at 19:59
