Read IMAP Email Headers

Call FetchHeaders to download only the email headers.

Chilkat Module for Perl 5.8.*

Chilkat Module for Perl 5.10.*

use chilkat;

$imap = new chilkat::CkImap();

#  Anything unlocks the component and begins a fully-functional 30-day trial.
$success = $imap->UnlockComponent("Anything for 30-day trial");
if ($success != 1) {
    print $imap->lastErrorText() . "\n";
    exit;
}

#  Connect to an IMAP server.
$success = $imap->Connect("mail.chilkatsoft.com");
if ($success != 1) {
    print $imap->lastErrorText() . "\n";
    exit;
}

#  Login
$success = $imap->Login("****","****");
if ($success != 1) {
    print $imap->lastErrorText() . "\n";
    exit;
}

#  Select an IMAP mailbox
$success = $imap->SelectMailbox("Inbox");
if ($success != 1) {
    print $imap->lastErrorText() . "\n";
    exit;
}

#  We can choose to fetch UIDs or sequence numbers.
$fetchUids = 1;

# messageSet is a CkMessageSet
$messageSet = $imap->Search("ALL",$fetchUids);

    exit;

#  When downloading headers, each email object contains
#  (obviously) the headers, but the body will be missing.
#  Also, attachments will not be included.  However, it is
#  possible to get information about the attachments
#  as well as the complete size of the email.

# bundle is a CkEmailBundle
$bundle = $imap->FetchHeaders($messageSet);
if ($bundle eq null ) {

    print $imap->lastErrorText() . "\n";
    exit;
}

#  Loop over the email objects and display information
#  about each:

for ($i = 0; $i <= $bundle->get_MessageCount() - 1; $i++) {

    # email is a CkEmail
    $email = $bundle->GetEmail($i);

    #  Display the From and Subject
    print $email->ck_from() . "\r\n";
    print $email->subject() . "\r\n";

    #  Display the recipients:

    for ($j = 0; $j <= $email->get_NumTo() - 1; $j++) {
        $name = $email->getToName($j);
        $addr = $email->getToAddr($j);

        print $name . ", " . $addr . "\r\n";
    }

    #  Show the total size of the email, including body and attachments:
    print $email->get_Size() . "\r\n";

    #  When a full email is downloaded, we would use the
    #  email.NumAttachments property in conjunction with the
    #  email.GetMailAttach* methods.
    #  However, when an email object contains only the header,
    #  we need to access the attachment info differently:
    $numAttach = $imap->GetMailNumAttach($email);
    for ($j = 0; $j <= $numAttach - 1; $j++) {
        print $imap->getMailAttachFilename($email,$j) . "\r\n";
        $attachSize = $imap->GetMailAttachSize($email,$j);
        print "    size = " . $attachSize . " bytes" . "\r\n";
    }

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

}

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