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. VB.NET

Dim success As Boolean = False

' 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.
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


' Get the message IDs of all the emails in the mailbox
Dim fetchUids As Boolean = True
Dim messageSet As New Chilkat.MessageSet
success = imap.QueryMbx("ALL",fetchUids,messageSet)
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Fetch the emails into a bundle object:
Dim bundle As New Chilkat.EmailBundle
Dim headersOnly As Boolean = False
success = imap.FetchMsgSet(headersOnly,messageSet,bundle)
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Loop over the bundle and display the FROM and SUBJECT of each.
Dim email As New Chilkat.Email
Dim i As Integer = 0
Dim numEmails As Integer = bundle.MessageCount
While i < numEmails
    bundle.EmailAt(i,email)

    Debug.WriteLine(email.From)
    Debug.WriteLine(email.Subject)
    Debug.WriteLine("--")
    i = i + 1
End While

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