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

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

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

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

' Get the number of messages in the mailbox.
numMessages = mailman.GetMailboxCount()

' Message numbers are specific to a POP3 session. 
' If a maildrop (i.e. inbox)  contains 10 messages, 
' the message numbers will be 1, 2, 3, ... 10. 
' If message number 1 is deleted and a new POP3 session 
' is established, there will be 9 messages numbered 1, 2, 3, ... 9. 

i = 1

Do While i <= numMessages

    ' email is a Chilkat.Email
    Set email = mailman.FetchByMsgnum(i)
    If (mailman.LastMethodSuccess <> 1) Then
        outFile.WriteLine(mailman.LastErrorText)
        WScript.Quit
    End If

    outFile.WriteLine(email.From & ": " & email.Subject & vbLf)

    i = i + 1
