Trying to understand email using php, SMTP server response: 550 5.7.1

[horseatingweeds]

I'm learning php and am trying to send a simple email using this script:

 

<?php

mail("info@gentledoberman.com", "This is the subject", "This is the body");

?>

 

I'm getting this error: SMTP server response: 550 5.7.1 apache

 

I am running this on a local apache server. What am I missing here?

 

This is the mail part of my php.ini

 

[mail function]

; For Win32 only.

SMTP = localhost

smtp_port = 25

 

; For Win32 only.

sendmail_from = me@example.com

 

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").

;sendmail_path =

 

; Force the addition of the specified parameters to be passed as extra parameters

; to the sendmail binary. These parameters will always replace the value of

; the 5th parameter to mail(), even in safe mode.

;mail.force_extra_parameters =

Do you have a local smtp server installed and configured?

I thought that was part of Apache. Do I need to find a smtp then?

Apache is a web server.
