Hi,

> Hat da jemand was Nettes?

ja:

function emailsaubermachen ($text)
{	
if ((strstr($text," ")) || (strstr($text,","))) {		// Q&D
    return "";
    }
if ( !eregi("[a-z0-9]+([-._]?[a-z0-9]+[-._]?)*[a-z0-9]+_(at)_(([a-z0-9-]+)[.])+[a-z]+",$text) && $text != "" ) {
    return "";
    }

// Teste Domain auf Existenz

$emsubstring = strstr($text, '_(at)_');
if (!$emsubstring) {
    return "";
    }
$emdomain = substr($emsubstring, -(strlen($emsubstring)-1));
$getmx=getmxrr($emdomain, $mxarray);
if (!$getmx) {
    return "";
    }
 
return $text;
} 

Gruß, Reinhold
