' The mailman object is used for receiving (POP3) 
' and sending (SMTP) email.
Dim mailman As New Chilkat.MailMan

' Set the POP3 server's hostname
mailman.MailHost = "pop.example.com"

' Set the POP3 login/password.

' 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.ImmediateDelete = False

' Download email headers.
