[ZendTo] Extra newlines and email headers

[Tony Fairbanks]

Hi,
I noticed that ZendTo is inserting double newlines after some email 
header fields, making portions of the header info show up in the message 
body. This causes problems, such as making "reply-to" not work.

The following chunk of code in lib/NSSDropbox.php originally had \r\n 
for the newline marker. By changing it to just \n the double newlines 
are removed.

  // Add the From: and Reply-To: headers if they have been supplied.
     if ($fromAddr!="") {
       $headers = sprintf("From: %s\nReply-to: %s\n", $sender, $fromAddr).
                  $headers;
     }

     // Add the MIME headrs for 8-bit UTF-8 encoding
     $headers .= "MIME-Version: 1.0\n";
     $headers .= "Content-Type: text/plain; charset=UTF-8; format=flowed\n";
     $headers .= "Content-Transfer-Encoding: 8bit\n";


This is with a fresh install of Scientific Linux 6.1 (RHEL clone) using 
Postfix, with ZendTo installed via the yum repository.

Thanks,
Tony
