Demonstrates how to send the CAPABILITY command to request a listing of capabilities that the IMAP server supports. A capability name which begins with "AUTH=" indicates that the server supports that particular authentication mechanism. Lianja

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

// Use TLS
loImap.Ssl = .T.
loImap.Port = 993
llSuccess = loImap.Connect("MY-IMAP-DOMAIN")

// 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:

    ? "IMAP server supports the QUOTA extension."
endif

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

// Disconnect from the IMAP server.
