Rust Requires Chilkat v11.0.0+

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. Rust

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

let imap = chilkat::Imap::new();

// Connect to an IMAP server.
// Use TLS
imap.set_ssl(true);
imap.set_port(993);
if imap.connect("imap.example.com").is_err() {
    println!("{}", imap.last_error_text());
    return;
}

// Login
if imap.login("myLogin", "myPassword").is_err() {
    println!("{}", imap.last_error_text());
    return;
}

// Select an IMAP mailbox
if imap.select_mailbox("Inbox").is_err() {
    println!("{}", imap.last_error_text());
    return;
}

// 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.
imap.set_peek_mode(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.
let num_emails = imap.num_messages();

let mset = chilkat::MessageSet::new();

// Indicate that mset contains sequence numbers, not UIDs.
mset.set_has_uids(false);

// 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.
let email = chilkat::Email::new();
let i = 0;
while i < num_emails {
    // Fetch the email by sequence number.
    if imap.fetch_email(false, (i + 1) as u32, false, &email).is_err() {
        println!("{}", imap.last_error_text());
        return;
    }

    // If it is decided to move the email, add the sequence number to mset, like this:
    mset.insert_id((i + 1) as u32);

}

// If there are emails in mset to be moved, then do it..
if mset.count() > 0 {
    let dest_folder = "Inbox/SomeOtherFolder".to_string();
    // Assuming your IMAP server supports the feature that allows for messages to be moved to another folder...
    if imap.move_messages(&mset, &dest_folder).is_err() {
        println!("{}", imap.last_error_text());
        return;
    }

}

// Disconnect from the IMAP server.
let _ = imap.disconnect().is_ok();
