Demonstrates how to download every email in an IMAP mailbox one at a time as a MIME string or as an email object. (The MIME contains the full contents of the email including all attachments.)

Dim imap As New Chilkat.Imap

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

' Connect to an IMAP server.
' Use TLS
imap.Ssl = True
imap.Port = 993
Dim success As Boolean = Await imap.ConnectAsync("imap.someMailServer.com")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Login
success = Await imap.LoginAsync("myLogin","myPassword")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Select an IMAP mailbox
success = Await imap.SelectMailboxAsync("Inbox")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Once the mailbox is selected, the NumMessages property
' will contain the number of messages in the mailbox.
' You may loop from 1 to NumMessages to
' fetch each message by sequence number.

Dim bUid As Boolean = False
Dim mimeStr As String
Dim i As Integer
Dim n As Integer = imap.NumMessages
For i = 1 To n

    ' Download the email by sequence number.
    mimeStr = Await imap.FetchSingleAsMimeAsync(i,bUid)

    ' ... your application may process each MIME string...
Next


' An alternative is to download each email in the form of an
' email object, like this:
Dim email As Chilkat.Email
For i = 1 To n

    ' Download the email by sequence number.
    email = Await imap.FetchSingleAsync(i,bUid)

    ' ... your application may process the email object...


Next

' Disconnect from the IMAP server.
success = Await imap.DisconnectAsync()
