Gets and sets the current message priority.
A string which specifies the message priority.
The Priority property returns the current priority for the message. Setting this property value causes the X-Priority header to be updated with the specified value.
There is no standard for specifying message priority. The convention is to use a number from 1-5, with 1 indicating the highest priority, 3 as normal priority and 5 as the lowest priority. Some mailers follow the number with a space and then text that describes the priority level.
