can't get new line chars to work

[Anon]

I have the following php3 code...

<?php

$sFields = "Senders Name:\t$sender_name";
$sFields .= "Senders Email:\t$sender_email";
$sFields .= "Senders Msg:\t$sender_message";
$mailto = "[e-mail]";
$subject = "Web Site Feedback";
$replyto = "Reply-To: $sender_email";

mail ($mailto, $subject, $sFields, "$replyto");
?>

and if I put \n at the end of my
$sFields line - then my mail won't send -
the minute I remove \n this works - then
when I send the mail everything is on
one line - can someone please tell me
how to put each one on a different line.

Make sure that you end each line with \n\r not just \n. Some SMTP servers don't like bare linefeeds and will not accept messages that contain them.
