' 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.
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.MailMan")
set mailman = Server.CreateObject("Chilkat.MailMan")

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

' Set the POP3 login/password.
mailman.PopUsername = "***"
mailman.PopPassword = "***"

' Copy the all email from the user's POP3 mailbox 
' into a bundle object.  The email remains on the server.
' CopyMail is a reasonable choice for POP3 maildrops that don't have too many
' emails. For larger mail drops, one might download emails one at a time..
' bundle is a Chilkat.EmailBundle
Set bundle = mailman.CopyMail()

' would be different..

    ' are automatically overwritten.  By default, it is set to 1 so that existing

    ' unique filenames if a file with the same name already exists.  The actual filename(s)
    ' saved will be present by calling GetAttachmentFilename for each attachment *after*
    ' saving.
