Send High-Priority Mail

VB.NET source code showing how to send a high-priority mail.

        Dim success As Boolean

        ' Create a mailman object for sending email.
        Dim mailman As New Chilkat.MailMan()

        ' Any string argument automatically begins the 30-day trial.
        mailman.UnlockComponent("30-day trial")

        ' Set the SMTP server.
        mailman.SmtpHost = "smtp.earthlink.net"

        ' Create a high-priority email.
        Dim email As New Chilkat.Email()

        ' Set the basic email stuff: body, subject, "from", "to"
        email.Body = "This is the email body"
        email.Subject = "This is the email subject"
        email.AddTo("Chilkat Support", "support@chilkatsoft.com")
        email.From = "Programmer <programmer@chilkatsoft.com>"

        'You can add the X-Priority header field and give it the value string "1". 
        'For example: email.AddHeaderField "X-Priority","1" This is the most common way of 
        ' setting the priority of an email. "3" is normal, and "5" is the lowest. 
        ' "2" and "4" are in-betweens, and frankly I've never seen anything 
        ' but "1" or "3" used. Microsoft Outlook adds these header fields when 
        ' setting a message to High priority: 
        ' X-Priority: 1 (Highest) 
        ' X-MSMail-Priority: High 
        ' Importance: High 
        ' This field alone is enough to make the email high-priority.
        email.AddHeaderField("X-Priority", "1")

        success = mailman.SendEmail(email)
        If success Then
            MessageBox.Show("Sent high-priority email!")
        Else
            MessageBox.Show(mailman.LastErrorText)
        End If
