I would like to ask how to set PHP.ini to be able to send emails from PHP scripts via MAIL() function - we do not have open relay SMTP, we use MS Server 2003 with regular default SMTP from MS Server 2003

and also can you give some easy sample example PHP script, which should work with the PHP.ini setting?

we would like also to be able to send emails from different email addresses from our PHP scripts hosted on our server

any ideas?

thanks!

I don't think PHP natively support SMTPS.

Authentication needs to take place before any conversation.

I would recommend using a mailer class (I use htmlMimeMail5 from http://phpguru.org, though I'm sure phpmailer - another common class - has this capability also).

This class has the following setSMTPParams method ...

setSMTPParams($host = null, $port = null, $helo = null, $auth = null, $user = null, $pass = null)

Set $auth to true and set $user and $pass and all goes as planned.

To send mail from different people, I use ...

ini_set('sendmail_from', 'address@site.com');

prior to any mail related activity.

You can also send SMTP to the recipients server rather than relaying it through your local server.

Using getmxrr() (Windows version attached as this is not supported natively on windows) you can find the actual SMTP server(s) for a particular email address and send it to that machine for processing.

So, something like ...

if (getmxrr('gmail.com', $a_MXHosts, $a_Weights)) {
 print_r($a_MXHosts);
 print_r($a_Weights);
}

outputs ...

Array
(
    [0] => gmail-smtp-in.l.google.com
    [1] => alt1.gmail-smtp-in.l.google.com
    [2] => alt2.gmail-smtp-in.l.google.com
    [3] => gsmtp163.google.com
    [4] => gsmtp183.google.com
)
Array
(
    [0] => 5
    [1] => 10
    [2] => 10
    [3] => 50
    [4] => 50
)

From this you can cycle through the MX Hosts, ini_set('SMTP', $a_MXHost[$i_Index]); and then send the email.

Or use the setSMTPParams($a_MXHost[$i_Index], ....) call.

If you wanted to AUTH yourself, YOU need to have an account on every server.

So, either use a local relay and you auth to it

OR

you send email directly to the recipients smtp server unauth'd, just like the rest of the internet does.




<?php
if (!function_exists('getmxrr')) {
	function getmxrr($s_HostName, array &$a_MXHosts = NULL, array &$a_Weights = NULL) {
		// Simulate all the required network activity by executing windows' NSLOOKUP.
		$s_NSLookup = shell_exec("nslookup -q=mx {$s_HostName} 2>nul");
		preg_match_all("'^.*MX preference = (\d{1,10}), mail exchanger = (.*)$'simU", $s_NSLookup, $a_MXMatches);
 
		// If there is something to return ...
		if (count($a_MXMatches[2]) > 0) {
			// Produce output arrays if they have been requested.
			$i_ArgCount = func_num_args();
			if ($i_ArgCount > 1) {
				array_multisort($a_MXMatches[1], $a_MXMatches[2]);
				switch ($i_ArgCount) {
					case 3 :
						$a_Weights = $a_MXMatches[1];
					case 2 :
						$a_MXHosts = $a_MXMatches[2];
				}
			}
			return True;
		} else {
			return False;
		}
	}
}
?>
