Dim success As Boolean
Dim mailman As New Chilkat.MailMan

// Set the SMTP server.
mailman.SmtpHost = "smtp.example.com"

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

email.Body = "This is a digitally encrypted mail"
email.From = "Joe <joe@example.com>"
// Emails are encrypted using the recipient's certificate.
Dim recipientEmailAddr As String

success = email.AddTo("Jane",recipientEmailAddr)

// Indicate that the email is to be sent encrypted.
email.SendEncrypted = True

// This example demonstrates finding the email encryption certificate
// on a Windows system where the certificate is stored in the Windows 
// certificate store.

Dim cert As New Chilkat.Cert
// The recipient's certificate is used to encrypt.
// (Because the recipient is the only one in possession of the private key to decrypt.)
success = cert.LoadByEmailAddress(recipientEmailAddr)
If (success <> True) Then
    System.DebugLog(cert.LastErrorText)
    Return
End If

// Specify the certificate to be used for encryption.
success = email.SetEncryptCert(cert)

success = mailman.SendEmail(email)
If (success <> True) Then
    System.DebugLog(mailman.LastErrorText)
Else
    System.DebugLog("Encrypted Mail Sent!")
