Help with PHP mail() function [duplicate]

php mail() function on localhost

I'm trying to do some localhost testing for password recovery on my site, but when I try to send an email, I get the following error:

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()

Here are the relevant settings in my php.ini file.

; For Win32 only.
; http://php.net/smtp
SMTP = localhost
; http://php.net/smtp-port
smtp_port = 25

; For Win32 only.
; http://php.net/sendmail-from
sendmail_from = you@yourdomain

I am not sure what to set these to for localhost testing. I realize that I need to set SMTP to whatever my provider's mail server is, but I work in a shared office building so I don't know how to even find out who provides the internet here.

Thanks in advance.

PHP's mail() function doesn't implement SMTP protocol directly. Instead it relies on sendmail() MTA (SMTP server), or a replacement like postfix or mstmp. It works fine on Unix as long as MTA installed.

On Windows (from PHP.net manual):

The Windows implementation of mail() differs in many ways from the Unix implementation. First, it doesn't use a local binary for composing messages but only operates on direct sockets which means a MTA is needed listening on a network socket (which can either on the localhost or a remote machine).

So - the moral of the story - you need to install mail server.

However - if it's for test purpose only - simply get a PHP library that actually implements SMTP protocol and use your regular gmail email address to send emails:

Instead of using PHP's mail() use one of these:

1. PHPmailer
2. SwiftMailer
3. Zend\Mail

These PHP libraries actually implement SMTP protocol so one can easily send emails from any platform, without email server installed on the same machine:

PHPMAILER example:

$mail->IsSMTP(); // telling the class to use SMTP
$mail->Host       = "stmp.gmail.com"; // SMTP server
$mail->SMTPDebug  = 1;                     // enables SMTP debug information (for testing)
// 1 = errors and messages
// 2 = messages only
$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->SMTPSecure = "ssl";                 // sets the prefix to the servier
$mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
$mail->Port       = 465;                   // set the SMTP port for the GMAIL server
$mail->Username   = "[email protected]";  // GMAIL username
$mail->Password   = "pass111";            // GMAIL password
$mail->SetFrom('[email protected]', 'My name is slim shady');
$mail->AddReplyTo("[email protected]","My name is slim shady");
$mail->Subject    = "Hey, check out http://www.site.com";
$mail->AltBody    = "Hey, check out this new post on www.site.com"; // optional, comment out and test
$mail->MsgHTML($body);
$address = "[email protected]";
$mail->AddAddress($address, "My name is slim shady");

PHP's mail requires a local mailserver to run.

Edit: As the PHP documentation site for mail() reveils, you may use a Mail package from PEAR.
