'  To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

'  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.
