(JavaScript) Delete All IMAP Email

Demonstrates two ways to delete all email in a mailbox on an IMAP server.

Note: This example requires Chilkat v11.0.0 or greater.

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

var imap = new CkImap();

// Turn on session logging:
imap.KeepSessionLog = true;

// Connect to an IMAP server.
// Use TLS
imap.Ssl = true;
imap.Port = 993;
success = imap.Connect("imap.example.com");
if (success == false) {
    console.log(imap.LastErrorText);
    return;
}

// Login
success = imap.Login("myLogin","myPassword");
if (success == false) {
    console.log(imap.LastErrorText);
    return;
}

// Select an IMAP mailbox
success = imap.SelectMailbox("Inbox.RubyMail");
if (success == false) {
    console.log(imap.LastErrorText);
    return;
}

// Get the complete set of Uids for email in the selected mailbox.
var messageSet = new CkMessageSet();
success = imap.QueryMbx("ALL",true,messageSet);
if (success == false) {
    console.log(imap.LastErrorText);
    return;
}

// Set the Deleted flag for each message.
// (ExpungeAndClose must be called to finalize the delete.)
success = imap.SetFlags(messageSet,"Deleted",1);
if (success == false) {
    console.log(imap.LastErrorText);
    return;
}

// Alternatively, the Deleted flag may be set for each UID
// individiually, but this is less efficient:
var i = 0;
var n = messageSet.Count;
while (i < n) {
    success = imap.SetFlag(messageSet.GetId(i),messageSet.HasUids,"Deleted",1);
    if (success == false) {
        console.log(imap.LastErrorText);
        return;
    }

    i = i+1;
}

// Expunge and close the mailbox.
success = imap.ExpungeAndClose();
if (success == false) {
    console.log(imap.LastErrorText);
    return;
}

// Display the session log.
console.log(imap.SessionLog);

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