Mark email before sending using any class of System.net.mail namespace
1 answer
I understand that the flag is not part of the POP / MIME / SMTP specifications and is just a sorting feature offered by many applications. You can set the value to high, normal and low.
MailMessage msg = new MailMessage
{
Priority = MailPriority.High,
Subject = "High priority message."
};
