DX Auth 1.0.6 (Authentication library)

dexcell,

Thanks for this authentication library. I have got it working just fine, but have one problem.
When I register a user, I get a php warning:

Code:

A PHP Error was encountered

Severity: Warning

Message: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set()

Filename: libraries/Email.php

Line Number: 1444

I'm using the latest version of CI and your code.
I set up an email.php config file for my app, and set the protocol to 'mail' but that didn't help.
Any ideas why that's happening?
