The new WAMP Server’s PHP and stand-alone PHP v5.3+, are now NOT available with some of the extensions required to implement the previous solution [PHPMailer] (there is a workaround to install the missing extension(s), described in the linked article). So an alternate and much less efficient (slower, but negligible low-speed for development platform (WAMP/localhost)) solution can be implemented, as below:
Solution:
This solution requires sendmail.exe (a Command Line Interface (CLI) executable which accepts email from PHP, connects to an SMTP server and sends email). You will not require to use it by command, don’t bother about it 
Download the sendmail.zip and follow these steps:
Download the sendmail.zip and follow these steps:- Create a folder named “sendmail” in “C:\wamp\”.
- Extract these 4 files in “sendmail” folder: “sendmail.exe”, “libeay32.dll”, “ssleay32.dll” and “sendmail.ini”.
- Open the “sendmail.ini” file and configure it as following
- smtp_server=smtp.gmail.com
- smtp_port=465
- smtp_ssl=ssl
- default_domain=localhost
- error_logfile=error.log
- debug_logfile=debug.log
- auth_username=[your_gmail_account_username]@gmail.com
- auth_password=[your_gmail_account_password]
- pop3_server=
- pop3_username=
- pop3_password=
- force_sender=
- force_recipient=
- hostname=localhost
- Enable IMAP Access in your GMail’s Settings -> Forwarding and POP/IMAP -> IMAP Access:
- Enable “ssl_module” module in Apache server:
- Enable “php_openssl” and “php_sockets” extensions for PHP compiler:
- Open php.ini from “C:\wamp\bin\apache\Apache2.2.17\bin” and configure it as following (The php.ini at “C:\wamp\bin\php\php5.3.x” would not work) (You just need to configure the last line in the following code, prefix semicolon (;) against other lines):
[mail function] ; For Win32 only. ; http://php.net/smtp ;SMTP = ; http://php.net/smtp-port ;smtp_port = 25 ; For Win32 only. ; http://php.net/sendmail-from ;sendmail_from = you@domain.com ; For Unix only. You may supply arguments as well (default: "sendmail -t -i"). ; http://php.net/sendmail-path sendmail_path = "C:\wamp\sendmail\sendmail.exe -t -i"
- Restart WAMP Server.
- Create a PHP file and write the following code in it:
<?php $to = 'recipient@yahoo.com'; $subject = 'Testing sendmail.exe'; $message = 'Hi, you just received an email using sendmail!'; $headers = 'From: sender@gmail.com' . "\r\n" . 'Reply-To: sender@gmail.com' . "\r\n" . 'MIME-Version: 1.0' . "\r\n" . 'Content-type: text/html; charset=iso-8859-1' . "\r\n" . 'X-Mailer: PHP/' . phpversion(); if(mail($to, $subject, $message, $headers)) echo "Email sent"; else echo "Email sending failed"; ?> - Make appropriate changes in $to and $headers variables to set recipient, sender and reply-to address. Save it as “send-mail.php”. (You can save it anywhere or inside any sub-folder in “C:\wamp\www”.)
- Open this file in browser, it MUST work now
