IMAP Download All Email One at a Time

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.) VB.NET

Dim success As Boolean = False

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
success = imap.Connect("imap.example.com")
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Login
success = imap.Login("myLogin","myPassword")
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Select an IMAP mailbox
success = imap.SelectMailbox("Inbox")
If (success = False) 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 = imap.FetchSingleAsMime(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 New Chilkat.Email
For i = 1 To n

    ' Download the email by sequence number.
    success = imap.FetchEmail(False,i,bUid,email)

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

Next

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