Currently reading up on the IMAP protocol, as one of my customers is using a server without IMAP support compiled :)

I will be using a simple INBOX check for failed email notifications (sockets are your best friend). That will allow me to set a flag for every new user account that is still unconfirmed and used a broken email address for their registration. These accounts can than be verified manually :)

Happy socket = happy customer.

Btw, here is a nice piece of code to quickly parse the email header in PHP

$parsed  = array();
$blocks  = preg_split('/\n\n/', $response['data']);
$lines   = array();
$matches = array();
foreach ($blocks as $i => $block) {
    $parsed[$i] = array();
    $lines = preg_split('/\n(([\w.-]+)\: *((.*\n\s+.+)+|(.*(?:\n))|(.*))?)/',
                        $block, -1, PREG_SPLIT_DELIM_CAPTURE);
    foreach ($lines as $line) {
        if(preg_match('/^\n?([\w.-]+)\: *((.*\n\s+.+)+|(.*(?:\n))|(.*))?$/',
                      $line, $matches)) {
            $parsed[$i][$matches[1]] = preg_replace('/\n +/', ' ',
                                                    trim($matches[2]));
        }
    }
}

$parsed = array();

$blocks = preg_split('/\n\n/', $response['data']);

$lines = array();

$matches = array();

foreach ($blocks as $i => $block) {

$parsed[$i] = array();

$lines = preg_split('/\n(([\w.-]+)\: *((.*\n\s+.+)+|(.*(?:\n))|(.*))?)/',

$block, -1, PREG_SPLIT_DELIM_CAPTURE);

foreach ($lines as $line) {

if(preg_match('/^\n?([\w.-]+)\: *((.*\n\s+.+)+|(.*(?:\n))|(.*))?$/',

$line, $matches)) {

$parsed[$i][$matches[1]] = preg_replace('/\n +/', ' ',

trim($matches[2]));

}
