SecurePop ActiveX Control

Use the SecurePop control to automatically authenticate and encrypt/decrypt all data sent and received over a POP3 connection using SSL2, SSL3, PCT, and TLS. Features include:

Use SSL 2.0, SSL 3.0, PCT, TLS or unencrypted TCP communications.
Customize certificate acceptance or rejection.
Client authentication fully supported.
Detailed knowledge of POP3 is not required.
Message object collection represents all messages on the server. Retrieve a single message, all messages, or a range of messages.
Retrieve entire messages, message headers only, or the specified amount of message lines.
Memory-based message retrieval makes this product perfect for ASP applications.
Powerful default operations are provided with the SecurePop control, including iteration through a message set to populate the Messages property.
The Message object provides an object representation of any e-mail message. This formatting object supports easy manipulation of simple and complex (even nested) MIME messages.

Code Example

How easy is the SecurePop control to use? This example demonstrates creating a basic secure POP mail client.

Private Sub SecurePopTest()
    ' Login to the secure POP server. The control will attempt
    ' to negotiate SSL
    SecurePop1.Login "myserver", "username", "pass"

    ' Success! SSL connection established. Get any messages
    SecurePop1.Get msgContent
    Debug.Print SecurePop1.Messages.Count & " messages retrieved."

    ' Logout
    SecurePop1.Logout
End Sub

Private Sub SecurePop1_Authenticate(ByVal RemoteCertificate As DartSecureMailCtl.ICertificate, 
ByVal TrustedRoot As Boolean, ByVal ValidDate As Boolean, ByVal ValidSignature As Boolean, 
Valid As Boolean)
    ' The server's certificate has been received.
     Dim Msg As String
    ' Check to see if it passed all the checks.
    If Not Valid Then
        ' It didn't, so check everything and give the user the option to accept/reject.
        If Not ValidDate Then Msg = Msg + "- Certificate date is invalid" + vbCrLf
        If Not TrustedRoot Then Msg = Msg + "- Certificate Authority is not trusted"
        + vbCrLf
        If Not ValidSignature Then Msg = Msg + "- Certificate does not contain a valid 
        signature" + vbCrLf
        Msg = "The following conditions are true:" + vbCrLf + vbCrLf + Msg + vbCrLf 
        + vbCrLf
        Msg = Msg + "Do you still wish to authenticate?"
        If MsgBox(Msg, vbYesNo + vbExclamation, "Security Alert") = vbYes Then
            ' User still wants to accept so accept it (by setting Valid to true)
            Valid = True
         End If
     End If
End Sub
