# See Global Unlock Sample for sample code.

# The typical port for IMAP SSL is 993

# Load a certificate from a PFX file and use it.
# Note: Other methods are available to load pre-installed
# certificates from registry-based certificate stores.

# Create an instance of a certificate store object, load a PFX file,
# locate the certificate we need, and use it for signing.
# (a PFX file may contain more than one certificate.)
