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. Perl

use chilkat();

$success = 0;

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

$imap = chilkat::CkImap->new();

# Connect using TLS.
$imap->put_Ssl(1);
$imap->put_Port(993);
$success = $imap->Connect("imap.example.com");
if ($success == 0) {
    print $imap->lastErrorText() . "\r\n";
    exit;
}

# Authenticate
$success = $imap->Login("email_account_login","email_account_password");
if ($success == 0) {
    print $imap->lastErrorText() . "\r\n";
    exit;
}

# Select an IMAP mailbox
$success = $imap->SelectMailbox("Inbox");
if ($success == 0) {
    print $imap->lastErrorText() . "\r\n";
    exit;
}

# Search for messages and return a set of matching messages.
# (This example will simply search for ALL messages.)
$fetchUids = 1;

$messageSet = chilkat::CkMessageSet->new();
$success = $imap->QueryMbx("ALL",$fetchUids,$messageSet);
if ($success == 0) {
    print $imap->lastErrorText() . "\r\n";
    exit;
}

print "Number of messages = " . $messageSet->get_Count() . "\r\n";

$email = chilkat::CkEmail->new();
$i = 0;
while ($i < $messageSet->get_Count()) {
    $success = $imap->FetchEmail(0,$messageSet->GetId($i),$fetchUids,$email);
    if ($success == 0) {
        print $imap->lastErrorText() . "\r\n";
        exit;
    }

    print $email->ck_from() . "; " . $email->subject() . "\r\n";

    $i = $i + 1;
}

print "OK" . "\r\n";
