(VB.NET UWP/WinRT) Secure IMAP over TLS/SSL

To communicate with an IMAP server over TLS/SSL, simply set the Ssl and Port properties. The remainder of your code is the same as with non-SSL.

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

Dim imap As New Chilkat.Imap

' To use a secure TLS/SSL connection, set the Ssl property and the port:
imap.Ssl = True
' The typical port for IMAP SSL is 993
imap.Port = 993

' Connect to an IMAP server.
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


' We can choose to fetch UIDs or sequence numbers.
Dim fetchUids As Boolean = True
' Get the message IDs of all the emails in the mailbox
Dim messageSet As Chilkat.MessageSet = Await imap.SearchAsync("ALL",fetchUids)
If (imap.LastMethodSuccess = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Fetch the emails into a bundle object:
Dim bundle As Chilkat.EmailBundle = Await imap.FetchBundleAsync(messageSet)
If (imap.LastMethodSuccess = False) Then

    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Loop over the bundle and display the FROM and SUBJECT of each.
Dim i As Integer = 0
Dim numEmails As Integer = bundle.MessageCount
While i < numEmails
    Dim email As Chilkat.Email = bundle.GetEmail(i)
    Debug.WriteLine(email.From)
    Debug.WriteLine(email.Subject)
    Debug.WriteLine("--")

    i = i + 1
End While

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