How to Download Messages in MessageSet One at a Time

See more IMAP Examples

If a message set contains a huge number of emails, it's NOT a good idea to try to download all at once into an email bundle using a method such as FetchBundle. It's better to iterate over the messages in the set to download one by one. PHP ActiveX

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

$imap = new COM("Chilkat.Imap");

// Connect using TLS.

$imap->Port = 993;
$success = $imap->Connect('imap.example.com');

// Authenticate
$success = $imap->Login('email_account_login','email_account_password');
if ($success == 0) {
    print $imap->LastErrorText . "\n";
    exit;

// Select an IMAP mailbox
$success = $imap->SelectMailbox('Inbox');
if ($success == 0) {
    print $imap->LastErrorText . "\n";
    exit;

// Search for messages and return a set of matching messages.
