Warning: 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() in

Ive opened up php.ini and i believe i need to add

SMTP “localhost” PHP_INI_ALL
smtp_port “25” PHP_INI_ALL

    You’re probably not running an SMTP server on your localhost.

    If you only need an SMTP server for development purposes, and you’re running Windows, install smtp4dev, which can be found here: http://smtp4dev.codeplex.com/

    It’s a beautiful little piece of software that sits in your task bar and lets you see all email that is being sent to it. It doesn’t actually send email anywhere, so you can work with live data without fear of spamming someone.

    Then, when you want your application to actually send email (when you run it on the server), you will need an SMTP server address instead of “localhost”. If you don’t know which SMTP to use, speak to your network administrator or ISP.

    Last but not least, if you access your email through an email program, you can probably find the “Outgoing server” in your settings somewhere, although that depends on which mail program you use. An “SMTP server” and an “Outgoing server” are exactly the same thing.
