I personally believe that if those substitutions are in fact all the same substitution, which seems to be the case -and would be most reasonable/probable- although I'm not sure due the alignment... then I should point out, on a totally OT basis wrt your actual problem, that you'd probably better do:

s{ \n\r | \r | \n }{\r\n}gx for
    $__to,
    $__cc,
    $__bcc,
    $__from,
    $__subject,
    $__html_message,
    $__text_message,
    $__importance,
    $__xpriority,
    $__x_ms_priority,
    $_mail_Message;
