got 503 smtp error

Hello,

just trying your lib, I can't even send a mail...

Got the error:

{ stack: [Getter/Setter],
  arguments: undefined,
  type: undefined,
  message: '503 sender not yet given\r' }

Here is my test file :

var email = require("mailer");
email.send({
  host : "localhost",              // smtp server hostname
  port : "25",                     // smtp server port
  to : "somewhere@free.fr",
  from : "root",
  subject : "node_mailer mémé test email",
  body: "Hello! This is a test & bière of the node_mailer."
},
function(err, result){
  if(err){ console.log(err); }
});

(Ubuntu, email server on localhost is exim).

regards,

Mickael

Start at the SMTP send path used by require("mailer") and reproduce the supplied test against localhost Exim. Trace how the from value "root" is sent and how the 503 response is handled; done when the example sends successfully or the cause is identified as an Exim configuration issue.
