sending email with cakephp2

I'm having problems sending a mail with cakephp2, I know I can send emails because I have my postfix configured, and I can send e-mails with command line or php. So please, can you send me an example of cakephp2 sending emails.

This is the error message

Invalid email: "you@localhost" Error: An Internal Error Has Occurred.

I've also tried with the ssl via gmail and it doesn't work either, and it's giving me a really hard time.

thanks guys

by the way, I'm trying the exact example of this url http://book.cakephp.org/2.0/en/core-utility-libraries/email.html
