Dim email As New Chilkat.Email

// The GetSignedByCertChain method is deprecated:

Dim certChainObj As Chilkat.CertChain
certChainObj = email.GetSignedByCertChain()
If (email.LastMethodSuccess = False) Then
    System.DebugLog(email.LastErrorText)
    Return
End If

// Do the equivalent using LastSignerCert to get the signing certificate,
// then build the cert chain from the signing certificate object.

// Get the certificate chain from the signer certificate.
Dim certChain As New Chilkat.CertChain
success = signerCert.BuildCertChain(certChain)
If (success = False) Then
