I can’t seem to get my php script to send email.

<?php 
echo "Does this page work?";
mail('my email address', 'test subject', 'test message');
?>

First, I have set the mail function settings in the php.ini file as follows:

I checked my email account settings on outlook. It does not require authentication, its port is 25, and its type of encrypted connection is ‘Auto’. Given this I configured my php.ini file accordingly:

SMTP = ssl://smtp1.iis.com
smtp_port = 25

Then I set:

sendmail_from = my email address

The echo statement prints out in the browser, so I know the php file is recognized and processed. But the browser also shows the following error:

Warning: mail() [function.mail]: "sendmail_from" not set in php.ini or custom "From:" header missing in C:\xampp\htdocs\mailtest.php on line 3

I have clearly set the sendmail_from so I don’t know what else to do. I have also tried removing the ‘ssl://’ part from the SMTP setting in the php.ini file, and configuring the php5.ini file. Which of these .ini files should I be configuring anyways?

    I now have an ANSWER to my question…

    I used phpinfo() to find out which php.ini file I was supposed to be editing. As it turned out, there were 3 such files available in my server folder. Two were under the PhP folder (named php.ini and php5.in respectively) and the other was in the apache/bin folder. Using the phpinfo() function, I was able to determine that I was editing the wrong .ini files (I looked at the parameters I was setting and the were not changing). Once I edited the correct one (the one in apache/bin) the Warning: mail() [function.mail]: “sendmail_from”…error stopped occurring.

    Then, to get the mail sent, I edited the correct .ini file as originally posed in my question:

    SMTP = myoutgoingmail.com (the same setting as my mail program - outlook)
smtp_port = (the same as my mail program - oultook)

sendmail_from = myemailaddress.com
