Description:
------------
Length of the encoded character string violates a RFC.
It violates a RFC when encoding a character string using the mb_encode_mimeheader function.

As for the e-mail header, the total of the field identifier, the field value and the line feed character is defined as being less than 76 characters.
It processes mb_encode_mimeheader function only using the field value.
Therefore, the field length at the head violates a RFC.

Reproduce code:
---------------
<?php
  declare( encoding="EUC-JP" );
  $A  = "??????????????????????????????????????????????????".
        "??????????????????????????????????????";

   $encode = mb_encode_mimeheader( $A, "EUC-JP", "B" );
   mail ( "s.masugata@digicom.dnp.co.jp", $encode, "TEST" );
?>

Thank you for reply. :)

Sorry, Mistaking by the sample scripts to have been specified by me of.
it's as the following:
<?php
  declare( encoding="EUC-JP" );


  $A      = "??????????????????????????????????????????????".
            "??????????????????????????????????????????????";

  $encode = mb_encode_mimeheader( $A, "EUC-JP", "B" );

   $Cc = "Cc: ".$encode." <s.masugata@digicom.dnp.co.jp>";
   mail( "s.masugata@digicom.dnp.co.jp", "TEST Subject", "TEST Body", $Cc );

?>

Cc: =?EUC-JP?B?pKKkoqSipKKkoqSipKKkoqSipKKkoqSipKKkoqSipKKkoqSipKKkoqSipKI=?=
 =?EUC-JP?B?pKKkoqSipKKkoqSipKKkoqSipKKkoqSipKKkoqSipKKkoqSipKKkoqSipKI=?=
 =?EUC-JP?B?pKKkog==?= <s.masugata@digicom.dnp.co.jp>

Because it doesn't consider a field identifier "Cc: " about the mb_encode_mimeheader function, the field length at the head exceeds 76 characters.

It found the patch which solves this problem.
