in reply to Sending a UTF-8 (Unicode) E-mail

I tried to add a date and a reply-to header. The date worked but not the reply-to. In strict, the reply-to throws an error 500 (can't have "reply" as stand alone word) and in non-strict, it just doesn't add it.

Do you know how to solve this issue? Are there more complete examples out there? So far, this page was the best to solve my accents problems in the headers. Utf-8 characters were not causing problems in the message body.

thanks,

Serge.

    Hi, I'm not fully up-to-date on the issue, but I did have this note in my archives, which I can't find the original source, but here it is: 
      Non USASCII characters *in headers* require special encoding:
  
  1)
   use Encode;
   $x="....";
   $x_for_header = Encode::encode('MIME-Q', $x);
   
    MIME-Q is the best for mostly USASCII strings
    MIME-B is the best for mostly non USASCII strings
   
    2) 
    Add one extra header to *fully* declare body encoding:
    print MAIL "Content-Transfer-Encoding: 8bit\n";

    Hope it helps.
