[php_student2]

I tried to send email from a php form to both hotmail & yahoo, the email contain flash banner, when i check my emails the flash not appearing, but when i check my email in my site using Neomail script, every thing in the message is right.

So, what do you think the problem is ?.

send file code:

<?
session_start();
ini_set("SMTP","LOCALHOST");

		    extract($HTTP_SESSION_VARS);
		    extract($HTTP_POST_VARS);
		    extract($HTTP_GET_VARS);
                session_register("mail_body");
                session_register("mail_subject");
                session_register("sender");
                session_register("mail_from");


$mail_headers = '';                    
			 	$mail_headers .= "From: $sender <$mail_from>\n";
				$mail_headers .= "Reply-to: $mail_from\n";
				$mail_subject = stripslashes($mail_subject);
				$mail_body = stripslashes($mail_body);

				$mail_headers .= "Content-type: text/html; charset=windows-1256\r\n";
				$mail_headers .= "Content-transfer-encoding:8bit\r\n\r\n";

mail("[e-mail]",$mail_subject,$mail_body,$mail_headers);
mail("[e-mail]",$mail_subject,$mail_body,$mail_headers);
?>

It might not be your code ... it could be that Hotmail and Yahoo! won't allow people to send Flash files to their users ... might be any number of reasons ...
