Can mail sender and recipient be identical?

[frozenpeas]

When I use a PHP script to send email, it works unless the sender and recipient are identical. Is this normal?

Thanks.

It may not have anything to do with PHP, but with your MTA settings.

What's your run environment?

Linux, Apache, Sendmail. Unfortunately I cannot give you much more detail because I do not run my own server.

$sender = $_SESSION['uname'];
$query = mysql_query("SELECT * FROM admin WHERE username = '$sender'") or die ('Could not query database: '.mysql_error());
while ($row = mysql_fetch_array($query)){
$header = &quot;From: &quot;.$row['name'].&quot;<&quot;.$row['email'].&quot;>&quot;.&quot;\r\n&quot;
		  .&quot;Reply-To: &quot;.$row['email'].&quot;\r\n&quot;
  		  .&quot;\&quot;MIME-Version: 1.0\&quot;\r\n&quot;
		  .&quot;Content-Type: text/plain;&quot;; 
$boundary = uniqid(&quot;EMAIL&quot;);
$toaddress = $_POST['select'];
$subject = $subject;
$mailcontent = $message
			   .&quot;\n&quot;.'--'.&quot;\n&quot;
			   .'This message was submitted by '.$_SESSION['uname'].' from '.$REMOTE_ADDR.'.&quot;\n&quot;;
mail($toaddress, $subject, $mailcontent, $header);
}

So if $toaddress and the "From:" header match, the send fails?

That is correct.

It must be your MTA. My LAMP box is running postfix, and I don't have that problem, even when running a modified version of the code you've posted.

Since I'm out of ideas, you might try contacting your service provider and ask them about the problem. It may be they have configured sendmail to not allow users to send mail to themselves.

Strange. Thanks for your help - I'll see what they have to say.
