Move Selected Emails to another Mailbox Folder

See more IMAP Examples

Downloads emails one by one in a selected mailbox, decides which emails are to be moved, and then moves the set of messages to another mailbox folder. JavaScript

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();

// Connect to an IMAP server.
// Use TLS
imap.Ssl = true;

// Normally, when an email is downloaded, its "Seen" flag is automatically set.
// We don't want our program to be interfering with the "Seen" flags.
// To do this, set the PeekMode to true.

// After selecting the mailbox, the NumMessages property
// will contain the number of emails in the mailbox.
// When sequence numbers (not UIDs) are used to reference emails,
// they range from 1 to N, where N is the number of messages in the mailbox.
// This example will download the headers by sequence numbers.

// Fetch each email and decide for each if it is to be moved
// to a particular other mailbox.  If so, we'll add the sequence number to
// the mset, and then move all emails in the mset to the other mailbox.
