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

Dim imap As New Chilkat.Imap

// Use TLS
imap.Ssl = True
imap.Port = 993
Dim success As Boolean
success = imap.Connect("MY-IMAP-DOMAIN")
If (success <> True) Then
    System.DebugLog(imap.LastErrorText)
    Return
End If

// Authenticate
success = imap.Login("MY-IMAP-LOGIN","MY-IMAP-PASSWORD")
If (success <> True) Then
    System.DebugLog(imap.LastErrorText)
    Return
End If

// Get the list of capabilities:
Dim caps As String
caps = imap.Capability()
System.DebugLog("Capabilities: " + caps)

// Here is an example of the string returned:
// * CAPABILITY IMAP4rev1 UNSELECT IDLE NAMESPACE QUOTA ID XLIST CHILDREN X-GM-EXT-1 
// UIDPLUS COMPRESS=DEFLATE ENABLE MOVE CONDSTORE ESEARCH UTF8=ACCEPT APPENDLIMIT=35882577
// LIST-EXTENDED LIST-STATUS

// Chilkat v9.5.0.58 introduces the HasCapability method to
// check to see if a particular capability exists:
If (imap.HasCapability("QUOTA",caps) = True) Then
    System.DebugLog("IMAP server supports the QUOTA extension.")
End If

If (imap.HasCapability("IDLE",caps) = True) Then
    System.DebugLog("IMAP server supports IDLE.")
End If

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