php mail() not working

[wasco]

Hi i am writing a php code to send email from my exchange server to user. however, keep receiving the the Warning message below:
Warning: Unknown error in c:\phpdev5\www\mailtest2.php on line 5

my php code:

<?php
$to = "[e-mail]";
$subject = "Hi!";
$body = "Hi,\n\nHow are you?";
if (mail($to, $subject, $body)) {
  echo("<p>Message successfully sent!</p>");
 } else {
  echo("<p>Message delivery failed...</p>");
 }
?>

php.ini setting:

[mail function]
; For Win32 only.
 
SMTP = gss-exchange1.example.com
SMTP_Port = 25
 
; For Win32 only.
 
sendmail_from = [e-mail]

Can anyone pls tel me what's wrong with my code or php setting?

Thanks.

wasco, you need to set up a real mailing server in order to send a real mail,
read more about mail() function on php.net ,
if you are on windows, try to use free smtp server http://www.softstack.com/freesmtp.html

if you are lucky mail will be sent !!!

also read abt setting up Gmail as SMTP server

Hi Hitendrap,

Thanks for your reply.

I have downloaded and installed the free smtp server; no luck for me, keeping getting "Waiting for connections on Port#25; using DNS Server: 170.133.125.2 (my company dns)

[hitendrap]

Remember that DNS server is not a mailing server (you need to get the IP of mail server from ur network admin, the DNS server contains the MX record for the mail server)

Make sure you also ask for the port number once you get thr mail serevr IP and set the configuration in PHP.INI

while your mailing program is being executed, just watch the freesmtpserver window, it shows the recipients e-mail address with hourglass icon before that !

Hi Hitendrap,

I have added SMTP address(Given by Network admin) to the php.ini and received the following message when i execute my php program:

Warning: Unknown error in c:\phpdev5\www\mailtest3.php on line 7

my php code:

$to = "[e-mail]";
$subject = "Test mail";
$message = "Hello! This is a simple email message.";
$from = "[e-mail]";
$headers = "From: $from";
 mail($to,$subject,$message,$headers);
echo "Mail Sent.";
?> 

Do i need to include the test2 (sender) user id and password in my php code in order to connect to my smtp mail server (exchange mail server)?

Thanks in advance!

Not necessary as far as the SMTP server allows without authentication.

and headers are optional in mail() function.

avoid writing words like test, example in mails even the addresses,
coz' some popular Mailing servers like Gmail, Yahoo may put your test mail in Spam OR even block the mail.
