SendMail setup for WampServer

Send email from localhost/WAMP Server using sendmail

Please try the previous solution first to send email from localhost if your WAMP Server version is 2.0c or older. Solution in this article is for those who are using WAMP Server newer than version 2.0c (may be when the version 5.3.x of PHP get bundled with WAMP, not sure).

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. So an alternate and much less efficient (slower, but negligible low-speed for development platform (WAMP/localhost)) solution can be implemented, as below:


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 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_port=465
    • smtp_ssl=ssl
    • default_domain=localhost
    • error_logfile=error.log
    • debug_logfile=debug.log
    • auth_username=[your_gmail_account_username]
    • auth_password=[your_gmail_account_password]
    • pop3_server=
    • pop3_username=
    • pop3_password=
    • force_sender=
    • force_recipient=
    • hostname=localhost

    You do not need to specify any value for these properties: pop3_server, pop3_username, pop3_password, force_sender, force_recipient. The error_logfile and debug_logfile settings should be kept blank if you have already sent successful email(s) otherwise size of this file will keep increasing. Enable these log file settings if you don’t get able to send email using sendmail.

  • 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.
    ;SMTP =
    ;smtp_port = 25
    ; For Win32 only.
    ;sendmail_from =
    ; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
    sendmail_path = "C:\wamp\sendmail\sendmail.exe -t -i"
  • Restart WAMP Server.
  • Create a PHP file and write the following code in it:
    $to       = '';
    $subject  = 'Testing sendmail.exe';
    $message  = 'Hi, you just received an email using sendmail!';
    $headers  = 'From:' . "\r\n" .
                'Reply-To:' . "\r\n" .
                'MIME-Version: 1.0' . "\r\n" .
                'Content-type: text/html; charset=iso-8859-1' . "\r\n" .
                'X-Mailer: PHP/' . phpversion();
    if(mail($to, $subject, $message, $headers))
        echo "Email sent";
        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 :-)
Update (2-Dec-2012)
Please ensure that 2-steps-verification is disabled in GMail if you are using GMail’s SMTP server to send email (sending email using GMail), otherwise you might get “Email sent” message but the email won’t get sent actually. (If you don’t know about 2-steps-verification, you don’t need to worry about it, it is disabled by default.) Thanks to Naveen.
Update (25-Mar-2013)
If the path to the sendmail.exe contains “space” (for example, “C:\Program Files\PHP\sendmail\”) then Apache would not be able to locate it. So, either store the sendmail.exe at a “non-spaced” location/path OR write the path in DOS style “C:\Progra~1\PHP\sendmail\” in the php.ini (sendmail_path = "C:\Progra~1\PHP\sendmail\sendmail.exe -t -i"). Thanks to Douglas.

Windows 8 users, please check Mark’s comment if email sending is failing (may be because of …
Socket Error # 10060
Connection timed out
Update (3-Apr-2013)
I think all possible errors are now covered in the comments section, so I am closing the posting of comments for this article. If you are getting any error or a message like “Email sending failed.”, you can send email to me at Please attach php.ini (C:\wamp\bin\apache\Apache2.2.8\bin\), httpd.conf (C:\wamp\bin\apache\apache2.2.8\conf), sendmail.ini and send-mail.php, along with the email; I will check all these files and reply with suggestion if any. Thanks you all for the overwhelming responses.
