# The GetSignedByCertChain method is deprecated:

certChainObj = email.GetSignedByCertChain()
if (email.LastMethodSuccess == False):
    print(email.LastErrorText)

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

    print(email.LastErrorText)

# Get the certificate chain from the signer certificate.
certChain = chilkat2.CertChain()
success = signerCert.BuildCertChain(certChain)
if (success == False):
