(JavaScript) IMAP Capability

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.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var imap = new CkImap();

// Use TLS
imap.Ssl = true;
imap.Port = 993;
success = imap.Connect("MY-IMAP-DOMAIN");
if (success !== true) {
    console.log(imap.LastErrorText);
    return;
}

// Authenticate
success = imap.Login("MY-IMAP-LOGIN","MY-IMAP-PASSWORD");
if (success !== true) {
    console.log(imap.LastErrorText);
    return;
}

// Get the list of capabilities:
var caps = imap.Capability();
console.log("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) {
    console.log("IMAP server supports the QUOTA extension.");
}

if (imap.HasCapability("IDLE",caps) == true) {
    console.log("IMAP server supports IDLE.");
}

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