Description
bool 
mb_send_mail ( string to, string subject, string message [, string additional_headers [, string additional_parameter]] )
     mb_send_mail() sends email. Headers and
     message are converted and encoded according to
     mb_language() setting. 
     mb_send_mail() is wrapper
     function of mail(). See
     mail() for details.
    
     to is mail addresses send to. Multiple
     recipients can be specified by putting a comma between each
     address in to. This parameter is not automatically encoded.
    
     subject is subject of mail.
    
     message is mail message.
    
     additional_headers is inserted at
     the end of the header. This is typically used to add extra
     headers.  Multiple extra headers are separated with a
     newline ("\n").
    
Note: 
      Content-Type and
      Content-Transfer-Encoding headers can be redefined as
      of PHP 5.0.0. In PHP 4, values defined by
      mb_language() are always used.
     
     additional_parameter is a MTA command line
     parameter. It is useful when setting the correct Return-Path
     header when using sendmail.
    
     Returns TRUE on success or FALSE on failure.
