I am using this:
/ recipients /
$email_list = "xxxxxx@xxxxland-corp.com" . "; " ; // note the comma
$email_list .= "wxxxxxk@yahoo.com";
/ To send HTML mail, you can set the Content-type header. /
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
/ additional headers /
$headers .= "To: Warren <xxxxxx@xxxxxand-corp.com>, Warren Yahoo <xxxxxxx@yahoo.com>\r\n";
$headers .= "From: ".$info['Email']."";
/ and now mail it /
mail("$email_list", "Bla Bla Bla", $message, $headers);
It works it the $email_list has only one address. If I add additional addresses It returns "Warning: Server Error in xxxx""; and does not send the mail.
I am running php 4.2.2 on Apache in Windows.
Any idea's?
