Hello,

Nice job but why do you require postfix?!

You should be using either sendmail/mailx or a custom user/password SMTPD server (e.g. google's smtpd).

sendmail and mailx require a running SMTP server on your computer, which we chose to be postfix.

To actually send the mails, we use the aptly named 'nodemailer' module, with the 'smtp' transport mechanism, which also relies on a running SMTP server. (btw, one can use a 'sendmail' transport mechanism).
