    ; To send high-priority email, 
    ; add the X-Priority header field with the value "1" 
    ; to indicate highest-priority.
    ; A value of "3" is normal, which is the same as not setting
    ; the X-Priority header at all, and "5" is the lowest. 
    ; "2" and "4" are in-betweens.

    ; Microsoft Outlook might add the following headers when
    ; sending high-priority email.

    ; X-Priority: 1 (Highest) 
    ; X-MSMail-Priority: High 
    ; Importance: High 

    ; The X-Priority header alone is enough to make the email high-priority.
