' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' The mailman object is used for sending and receiving email.
Dim mailman As New Chilkat.MailMan

' Set the SMTP server.
mailman.SmtpHost = "smtp.mymailserver.com"

' Create a new email object
Dim email As New Chilkat.Email

email.Subject = "This email is signed"
email.Body = "This is a digitally signed mail"
email.From = "Chilkat Admin <admin@chilkatsoft.com>"
Dim success As Boolean = email.AddTo("Chilkat Support","support@chilkatsoft.com")

' Indicate that the email should be sent signed.
email.SendSigned = True

' Tell the mailman to use a PFX file as a source for locating
' the certificate and private key required for signing.
' The certificate chosen for signing will be the one that
' matches the sender's email address, which also has
' a private key.  All intermediate certs in the chain of 
' authentication, up to and including the root, will
' be included in the signature.
success = mailman.AddPfxSourceFile("/pfx_files/chilkatsoft_secret.pfx","secret")
If (success <> True) Then
    Debug.WriteLine(mailman.LastErrorText)
    Exit Sub
End If



' Send a signed email.
success = Await mailman.SendEmailAsync(email)
If (success <> True) Then
    Debug.WriteLine(mailman.LastErrorText)
Else
    ' The LastErrorText property provides information
    ' even when successful.
    Debug.WriteLine(mailman.LastErrorText)
    Debug.WriteLine("Mail Sent!")
End If
