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

loImap = createobject("CkImap")

// Use TLS
loImap.Ssl = .T.
loImap.Port = 993
llSuccess = loImap.Connect("MY-IMAP-DOMAIN")
if (llSuccess <> .T.) then
    ? loImap.LastErrorText
    release loImap
    return
endif

// Authenticate
llSuccess = loImap.Login("MY-IMAP-LOGIN","MY-IMAP-PASSWORD")
if (llSuccess <> .T.) then
    ? loImap.LastErrorText
    release loImap
    return
endif

// Get the list of capabilities:
lcCaps = loImap.Capability()
? "Capabilities: " + lcCaps

// 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 (loImap.HasCapability("QUOTA",lcCaps) = .T.) then
    ? "IMAP server supports the QUOTA extension."
endif

if (loImap.HasCapability("IDLE",lcCaps) = .T.) then
    ? "IMAP server supports IDLE."
endif

// Disconnect from the IMAP server.
llSuccess = loImap.Disconnect()
