Sending e-mail from localhost in PHP in Windows Environment

Have you ever been frustrating, why e-mail is not going from the localhost while using XAMPP or WAMP or any other PHP servers in windows environment? well in that situation i think i can help you.In this article i am going to tell you how to send e-mail from localhost in PHP.

1) Open the “php.ini“. You should know where it is located because it depends upon the particular server you’re running.

2) Search for the attribute called “SMTP” in the php.ini file.Generally you can find the line “SMTP=localhost“. change the localhost to the smtp server name of your ISP. And, there is another attribute called “smtp_port” which should be set to 25.I’ve set the following values in my php.ini file.

smtp_port = 25

3) Restart the apache server so that PHP modules and attributes will be reloaded.

4) Now try to send the mail using the mail() function ,

mail(“”,”test subject”,”test body”);

you might get the warning like this,

Warning: mail() [function.mail]: “sendmail_from” not set in php.ini or custom “From:” header missing in C:\Program Files\xampp\htdocs\testmail.php on line 1

5) Now specify the following headers and try to send the mail again,

$headers = ‘MIME-Version: 1.0′ . “\r\n”;
$headers .= ‘Content-type: text/html; charset=iso-8859-1′ . “\r\n”;
$headers .= ‘From:’ . “\r\n”;
mail(“”,”test subject”,”test body”,$headers);

Well that’s all, the mail is sent to “” from the localhost.

Note : Some smtp server verifies the email address of the sender so the email address which is in the place of “” should be a valid and existing email address otherwise mail might not be sent to the “”.

    Warning: mail() [function.mail]: SMTP server response: 450 This mail is temporarily denied in C:\xampp\htdocs\T.php on line 5
    what is this mean???

  17. Kyle

    Thanks for the great tip!
    I found that you can use the ini_set() function directly inside your php script to achieve the same desired outcome when sending from localhost (I wanted to send from localhost for testing prior to uploading to my web server). Simply include the two lines below in your script directly before the mail() function. I am running WAMP on Windows Vista.
    ini_set(‘SMTP’, ‘’);
    mail(to, subject, message);

    how do i configure the smtp server in such a case- cant i directly use localhost or can i use my ip address in the lan which i am in.

    i am using xampp

  26. Rajesh

    The best practice for test environment windows platform would be using ini_set() within your PHP script:

  27. vlad

    You also have to set sendmail_from = property when setting your smtp staff in mail function in php.ini file, at list on wamp you have to do that.

  28. Sumit Joshi

    Hi, Dear Roshan.
    I use WAMP server in my local machine. I set the php.ini file as you have given in this tutorial and also tried from other sites. But I am not able to send mail from my local machine to other mail id.

    Please help me out.
    Thanks in advance.

    thanks in advance

  31. hanks for this post, budddy!

  32. i’m using WAMP and it success to send.. thank you…

  33. WhydoIneedaname?

    I tried to follow this as closely as possible, and it worked out pretty well. After step 4 I got the warning you mentioned, so I put in the headers and now I’m getting this message:

    “Parse error: syntax error, unexpected ‘:’ in C:\AppServ\www\test.php on line 86″

    Line 86 being:
    “$headers = ‘MIME-Version\: 1.0? . “\r\n”;”

    I’m not very good at this, but I’d really appreciate any suggestion about what I might be doing wrong.

  34. Kohake

    I was following this guide, and after step four I got the warning message you said I might get, so I just went on with step five. The result was this:
    “Parse error: syntax error, unexpected ‘:’ in C:\AppServ\www\test.php on line 86″

    Line 86 contains this: $headers = ‘MIME-Version: 1.0? . “\r\n”;

    I don’t know what to do, because removing the “:” only get’s me this error:
    Parse error: syntax error, unexpected T_DNUMBER in C:\AppServ\www\test.php on line 86
    Please help.

  35. Great, this solved exactly the problems I had.

    Hi Roshan,

    This Aditya started learning php recently so,please help me out with this problem.
    Actually i am trying to test email in PHP through wamp server but i am getting the following error.

    Warning: mail() [function.mail]: Failed to connect to mailserver at “” port 25, verify your “SMTP” and “smtp_port” setting in php.ini or use ini_set() in C:\wamp\www\Simplemailprg.php on line 11

    for your reference i am giving you the code i am using.
