Dim mailman As New 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.
Dim numMessages As Integer = Await mailman.GetMailboxCountAsync()

' 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. 

Dim i As Integer = 0


Dim email As Chilkat.Email
While i < numMessages

    email = Await mailman.FetchByMsgnumAsync(i)

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