# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# The mailman object is used for receiving (POP3) 
# and sending (SMTP) email.
mailman = Chilkat::CkMailMan.new()

# Set the POP3 server's hostname
mailman.put_MailHost("pop.someMailServer.com")

# Set the POP3 login/password.
mailman.put_PopUsername("myLogin")
mailman.put_PopPassword("myPassword")

# Set the ImmediateDelete property = false
# When the DeleteEmail method is called, the POP3 session
# will remain open and the emails will be deleted all at once
# when the session closes.
mailman.put_ImmediateDelete(false)

# Download email headers.

    # If you decide the email is to be deleted, call DeleteEmail.
    # This marks the email for deletion on the POP3 server.
