Transition from Email.GetSignedByCertChain to Email.LastSignerCert

Provides instructions for replacing deprecated GetSignedByCertChain method calls with LastSignerCert. Xojo Plugin

Dim success As Boolean

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.
