Determine the Number of Unseen Email Messages

Demonstrates how to determine how many unseen messages exist in an email account on an IMAP server. 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 to an IMAP server.
# Use TLS
$imap->put_Ssl(1);
$imap->put_Port(993);
$success = $imap->Connect("imap.example.com");
if ($success == 0) {
    print $imap->lastErrorText() . "\r\n";
    exit;
}

# Login
$success = $imap->Login("***","***");
if ($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;
}

# After selecting the mailbox. the total number of emails
# is immediately available:
$totalNum = $imap->get_NumMessages();
print "Num messages = " . $totalNum . "\r\n";

# To determine the number of unseen messages, a call
# to Search is required, which returns the set of UIDs
# of all unseen messages.

# We can choose to fetch UIDs or sequence numbers.
$fetchUids = 1;
$messageSet = chilkat::CkMessageSet->new();
$success = $imap->QueryMbx("UNSEEN",$fetchUids,$messageSet);
if ($success == 0) {
    print $imap->lastErrorText() . "\r\n";
    exit;
}

$numUnseen = $messageSet->get_Count();
print $numUnseen . "\r\n";

print "UIDs ----" . "\r\n";

# Display the UIDs
$i = 0;
while ($i < $messageSet->get_Count()) {
    print $messageSet->GetId($i) . "\r\n";
    $i = $i + 1;
}

# Disconnect from the IMAP server.
$success = $imap->Disconnect();
