(Visual Basic 6.0) 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 ChilkatImap

' To use a secure TLS/SSL connection, set the Ssl property and the port:
imap.Ssl = 1
' The typical port for IMAP SSL is 993
imap.Port = 993

' Connect to an IMAP server.
Dim success As Long
success = imap.Connect("imap.someMailServer.com")
If (success <> 1) Then
    Debug.Print imap.LastErrorText
    Exit Sub
End If

' Login
success = imap.Login("myLogin","myPassword")
If (success <> 1) Then
    Debug.Print imap.LastErrorText
    Exit Sub
End If

' Select an IMAP mailbox
success = imap.SelectMailbox("Inbox")
If (success <> 1) Then
    Debug.Print imap.LastErrorText
    Exit Sub
End If

' We can choose to fetch UIDs or sequence numbers.
Dim fetchUids As Long
fetchUids = 1
' Get the message IDs of all the emails in the mailbox
Dim messageSet As MessageSet
Set messageSet = imap.Search("ALL",fetchUids)
If (imap.LastMethodSuccess = 0) Then
    Debug.Print imap.LastErrorText
    Exit Sub
End If

' Fetch the emails into a bundle object:
Dim bundle As ChilkatEmailBundle
Set bundle = imap.FetchBundle(messageSet)
If (imap.LastMethodSuccess = 0) Then

    Debug.Print imap.LastErrorText
    Exit Sub
End If

' Loop over the bundle and display the FROM and SUBJECT of each.
Dim i As Long
i = 0
Dim numEmails As Long
numEmails = bundle.MessageCount
Do While i < numEmails
    Dim email As ChilkatEmail
    Set email = bundle.GetEmail(i)
    Debug.Print email.From
    Debug.Print email.Subject
    Debug.Print "--"

    i = i + 1
Loop

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