Nodemailer and Mailgun

Question

I'm getting an authentication error when using Nodemailer with Mailgun. Nodemailer docs state that the library works nicely with Mailgun SMTP, but I keep getting this error when running my app:

{ [AuthError: Invalid login - *** *.*.* Mailgun is not loving your login or password]
  name: 'AuthError',
  data: '*** *.*.* Mailgun is not loving your login or password',
  stage: 'auth' }

This is how I set up my transport:

@Transport = nodemailer.createTransport("SMTP",
     service: "Mailgun"
     auth:
         user: "api"
         pass: "**********************"
)

I'm 100% sure my api key is correct. Are there any other requirements I'm missing?

For what it's worth, it works perfectly when I use a Gmail address.

Answer 1

you cannot use api key with smtp transport.

Go to mailgun console and grab smtp credentials from domain config and use those.
