Auth error using node mailer as smtp server

[csemeria]

I'm using node mailer as an smtp server and I also have a domain redirected to my server. When I send mails I get "530 Error: authentication Required". In early tests I tried using telnet and it's all ok if I send anything but an empty user or pass, but senfin a mail using gmail ends up in this error. My first idea would be to learn is it's possible to skip auth process entirely but I'm open to other options in they fix the problem.
