Flagging an email before sending using any class of System.net.mail namespace

Question

Is it possible to "Flag an email" for followup using SMTPClient/MailMessage classes in .NET?

Answer 1

It's my understanding that the flag is not part of the POP/MIME/SMTP specs and is simply a sorting feature offered by many applications. You can set the importance high, normal and low.

MailMessage msg = new MailMessage
{
    Priority = MailPriority.High,
    Subject = "High priority message."
};
