Also so (mit Header) geht's auf jedenfall:
Code:
$header="From:Kontakt-PriDev<matze@pri-dev.net>\n";
$header .= "Reply-To: " . $receiver_email;
$header .= "X-Mailer: PHP/" . phpversion(). "\n";
$header .= "X-Sender-
IP: $REMOTE_ADDR\n";
$header .= "Content-Type: text/
html";
$emailbody = 'EMail-Text';
//E-Mail versenden
//================
mail(matze@pri-dev.net,'Kontakt-PriDev',$emailbody,$header);
