I recently had to set up my Graffiti CMS blog to send email with my Gmail account, because I don’t pay for email on my domain.  I realized in the process, that I couldn’t really find a lot about how to do this.  I used some code I found while researching an auto emailer program and popped in the server, port and ssl information and Voila!  Email works like a charm. 

Just go into the Site Options under Email settings and put in the info.  The mojo is in using port 587 and smtp.gmail.com as the server.  Make sure you check the option to Use SSL.  Your “from” address can be any text formatted as an email address  (I used “admin@crazeegeekchick.com").  For the user and password, I entered my gmail account information.  It works great.
