Development Comments Off PHP Email Bounce Script
A lot of people have asked for this. This is the email bounce script I use. You will have to pipe all emails to this file.
<?
//opens the stream
$fd = fopen("php://stdin", "r");
$content = "";
//read the lines
while (!feof($fd))
{
$content .= fread($fd, 1024);
}
fclose($fd);
$lines = explode("\n", $content);
$email = "";
//SPAM report from feedback loop
for($i=0;$i<count($lines);$i++)
{
if(preg_match("/^Original-Rcpt-To:(.*)/", $lines[$i], $matches))
{
$email = trim($matches[1]);
$mode = "spam";
$type = 2;
continue;
}
}
//bounced back message from receiving server
if($email == "")
{
for($i=0;$i<count($lines);$i++)
{
if(preg_match("/^Delivered-To:(.*)/", $lines[$i], $matches))
{
$mode = "bounce";
$type = 1;
$email = substr(trim($matches[1]),2);
continue;
}
}
}
//failed message, MTA emailed a failed message
if($email == "")
{
for($i=0;$i<count($lines);$i++)
{
if(preg_match("/^Remote host said:(.*)/", $lines[$i], $matches))
{
for($j=0;$j<count($lines);$j++)
{
if(preg_match("/^Return-Path:(.*)/", $lines[$j], $matches))
{
if(strstr($matches[1], "=") !== false)
{
$mode = "bounce";
$type = 1;
$email = trim($matches[1]);
continue 2;
}
}
}
continue;
}
}
}
//return-path format is user=website.com@mydomain.com
//convert this into the actually email, user@website.com
if($mode == "bounce")
{
$email = substr($email,0,strpos($email,"@"));
$email = str_replace("=", "@", $email);
}
if($email != "")
{
if(strchr($email, "@") !== false)
{
$domain = substr($email,strpos($email,"@")+1);
$sql = "SELECT id
FROM donotemail
WHERE LOWER(email) = LOWER('".fix($email)."')";
$result = query($sql);
if($result)
{
if(numrows($result) == 0)
{
$sql = "INSERT INTO donotemail
(email, type, thedate)
VALUES('".fix($email)."', '$type', CURDATE())";
query($sql);
}
}
}
}
?>
