ActiveX for 32-bit and 64-bit Windows

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

' The mailman object is used for receiving (POP3) 
' and sending (SMTP) email.
Dim mailman As New ChilkatMailMan

' Set the POP3 server's hostname
mailman.MailHost = "pop.someMailServer.com"

' Set the POP3 login/password.
mailman.PopUsername = "myLogin"
mailman.PopPassword = "myPassword"

' If running on Microsoft Windows, the Chilkat mailman
' will automatically search the registry-based certificate stores
' for matching certificates and private keys required for
' decryption.  However, on Linux, MAX OS X, and other
' operating systems, no such thing exists.  Therefore, you'll 
' need to specify one or more PFX (.p12 / .pfx) files as
' sources for locating the certs required for decyrption.
Dim success As Long
success = mailman.AddPfxSourceFile("/pfxFiles/certs_and_keys_1.pfx","pfxPassword1")
If (success <> 1) Then
    Debug.Print mailman.LastErrorText
    Exit Sub
End If

success = mailman.AddPfxSourceFile("/pfxFiles/certs_and_keys_2.pfx","pfxPassword2")
If (success <> 1) Then
    Debug.Print mailman.LastErrorText
    Exit Sub
End If

' ...
' Note: On MS Windows, it is not required to provide PFX sources
' if the needed certs and private keys are already installed
' on the system (in the registry-based certificate stores).

' Copy the all email from the user's POP3 mailbox 
' into a bundle object.  The email remains on the server.
Dim bundle As ChilkatEmailBundle
Set bundle = mailman.CopyMail()
If (mailman.LastMethodSuccess = 0) Then
    Debug.Print mailman.LastErrorText
    Exit Sub
End If

' S/MIME security envelopes are automatically "unwrapped" 
' when a message is retrieved from the server. Signed emails are automatically verified, and 
' encrypted emails are automatically decrypted, restoring the email to the original state before 
' signing and/or encrypting. Information about the signing and encrypting certificates can be 
' retrieved from the Email object (methods: GetSignedByCert, GetEncryptedByCert; 
' properties: SignedBy, EncryptedBy, SignaturesValid, Decrypted, ReceivedSigned, 
' ReceivedEncrypted).

' Loop over the bundle, 
Dim i As Long
i = 0
Do While i < bundle.MessageCount
    Dim email As ChilkatEmail

    Debug.Print email.From
    Debug.Print email.Subject

    ' At this point, if the email was signed and/or encrypted, it is already "unwrapped", i.e.
    ' the email is already decrypted and in a state as if it were never signed or encrypted.
    ' You may check to see if the email was received encrypted or signed, and if so,
    ' whether it was successfully unwrapped and who signed or encrypted it:
    If (email.ReceivedEncrypted = 1) Then

        Debug.Print "This email was encrypted when received."
