PHP Mail stops working without me editing the code
I've had a problem with a clients mail function for a while. The thing is that the mail I use to receive the mails stops receiving mails from time to time. I've noticed this because when I change from my clients mail (info#allflytt.com) to my own (daniel#codia.se) it starts working properly. Also the "success function" gives me the message "The mail was not sent." when I use my clients mail (info#allflytt.com). So the problem seems to be located in the mailadress wich somehow, sometimes, doesn't accept the mails. This happens a couple of times every day and all I can do is wait for it to work again. I've posted the code below.
<?php
if(isset($_POST['submit'])){
$mottagare = 'info#allflytt.com';
$titel = 'Meddelande';
$namn = strip_tags($_POST['namn']);
$foretag = strip_tags($_POST['foretag']);
$adress = strip_tags($_POST['adress']);
$postnr = strip_tags($_POST['postnr']);
$ort = strip_tags($_POST['ort']);
$telefon = strip_tags($_POST['telefon']);
$epost = strip_tags($_POST['epost']);
$meddelande = strip_tags($_POST['meddelande']);
$meddelande=nl2br($meddelande);
$body =
"
Namn: <b>". $namn ."</b><br />
Företag: <b>". $foretag ."</b><br />
Adress: <b>". $adress ."</b><br />
Postnr: <b>". $postnr ."</b><br />
Ort: <b>". $ort ."</b><br />
Telefon: <b>". $telefon ."</b><br />
E-post: <b>". $epost ."</b><br /><br />
Meddelande: <b><br />". $meddelande
;
$headers = 'From: '. $namn .' <webmaster#allflytt.com>' . "\r\n";
$headers .= 'Content-type: text/html; charset=utf-8' . "\r\n";
$headers .= 'X-Mailer: PHP/' . phpversion();
$success = mail($mottagare, $titel, $body, $headers);
}
?>
<?php
if(!($success)){
echo "<p class=\"field_error\">The mail was not sent.</p>";
}
?>
<?php
if($success){
echo "<p class=\"p_success\">Great! The mail was sent.</p>";
}
?>
<form method="post" action="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>">

Answer 1

The problem is likely with the $namn variable, which can get practically any value, and therefore could either not be a valid e-mail at all, or could be an e-mail that's being blocked by the recipient.
Firstly you should make sure that $namn is a valid e-mail, but personally I would recommend that you use a single constant address for your From, preferably one the domain of which resolves to your mail server's IP.

Answer 2

Problem solved. Changed to a new server host. No issues any more!
