Custom php.ini file?

[Losty]

Alright so here's the dealio.

 

I created a basic feedback form with PHP. Did it, but received the following error:

 

Warning: mail() [function.mail]: SMTP server response: 553 sorry, that domain isn't allowed to be relayed thru this MTA (#5.7.1) in [file] on line 116

 

I looked into this and it seems that I need to config “SMTP” in the php.ini file.

 

The Problem: After calling the php info, I'm pretty sure it's my webhost that has access to this file. I contacted them, and they replied by telling me to create a custom one, as they are a "Microsoft Windows 2003 Server that specialize in ASP, ASP.NET, and SQL Server. We have limited experience with PHP."

 

So after swearing and cursing them out, I did some more snooping around to figure out how to create my own, and edit the SMTP settings.

 

Could I create my own php.ini file from this template: http://cvs.php.net/viewvc.cgi/php-src/php.ini-dist?view=co

 

And then add:

 

[mail function]

; For Win32 only.

SMTP = mail.host.com ; for Win32 only

smtp_port = 25

sendmail_from= [email protected] ; for Win32 only

 

; For Win32 only.

;sendmail_from = [email protected]

; For Unix only. You may supply arguments as well (default: "sendmail -t -i").

;sendmail_path =

 

; Force the addition of the specified parameters to be passed as extra parameters

; to the sendmail binary. These parameters will always replace the value of

; the 5th parameter to mail(), even in safe mode.

;mail.force_extra_parameters =

 

 

And if I can use that:

 

1. Where would I upload this file?

2. Would I run into issues with the php.ini file the site is already pointing to?

 

ANY help would be greatly appreciated.

It's likely that you are putting the email address that was entered in the form into the From: header. The From: email address must be an email address hosted on the sending mail server. You should put any email address that was entered in the form into the Reply-to: header.

I'm a bit of a newbie at PHP coding.

 

This is the code I'm using:

 

<?php

if (isset($_REQUEST['email']))

//if "email" is filled out, send email

  {

  //send email

  $email = $_REQUEST['email'] ;

  $subject = $_REQUEST['subject'] ;

  $message = $_REQUEST['message'] ;

  mail( "[email protected]", "Subject: $subject",

  $message, "From: $email" );

  echo "<h2>Thank you for sending us Feedback. We will reply within 2 business days.</h2>";

  }

else

//if "email" is not filled out, display the form

  {

  echo "<h2>Can't send email to $email . Please hit the back button in your browser and try again.</h4>";

  }

?>

 

 

 

Have I made a mistake somewhere?

PFMaBiSmAd spelled it out for you: the "From: $email" is probably being blocked by the mail server because it doesn't allow relaying. Use "Reply-to: $email" instead.

 

Also, I'd validate that the provided email address is a real email address and doesn't include an exploit that hackers can use to send spam.

 

<?php
$emailFilter="/^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i";
if(preg_match($emailFilter,$email) mail( "[email protected]", "Subject: $subject", $message, "Reply-to: $email");
else echo "error with email address."
?>
