mail function problem

I installed php on my Windows-ME machine. Most of it works properly. One problem is that the mail function doesn't work. I used: mail("pfortier@uottawa.ca", "My Subject", "Line 1\nLine 2\nLine 3"). Below is how I setup php, smtp server address added to php.ini, php program I tested, and its output. How could I get mail() function to work? Pierre Fortier pfortier@uottawa.ca Summary of setup - created directory C:\PROGRA~1\Sambar\Php which contains the files install.txt php.exe php4isapi.dll License Test.php and directories uploadtemp and sessiondata - php.ini is in \windows directory - php4ts.dll is in the system directory - autoexec.bat file contains SET PHPRC=C:\PROGRA~1\Sambar\Php and C:\PROGRA~1\Sambar\Php; in the PATH definition - C:\PROGRA~1\Sambar\config\mappings.ini has the following entry *.php = C:\PROGRA~1\Sambar\Php\php4isapi.dll php.ini includes [mail function] SMTP= smtp-out.uottawa.ca PHP program http://hawk.med.uottawa.ca/MailTest.php <html> <head> <title>Example</title> </head> <body> <?php $i=10; echo "Hi, I'm a PHP script!
