Sending eMail with Rails on Mac OS X Development Environment

You’ll need a mail transport agent (MTA). I installed and used postfix using Mac Ports.

sudo port install postfix

You’ll need to start postfix, to send mail from your Rails application. You can set it as a startup item and it will start on boot. However, since I don’t send too much mail from my Rails app, just for testing normally, I start it manually.

sudo postfix start

That should do it!
