Fetch a Range of POP3 Messages

See more POP3 Examples

Demonstrates the Chilkat MailMan.FetchRange method, which retrieves a range of messages from the POP3 mailbox and appends them to an EmailBundle. The arguments are keepOnServer, headersOnly, numBodyLines, a zero-based inclusive startIndex and endIndex, and the EmailBundle. This example fetches the first five messages.

// Demonstrates the MailMan.FetchRange method, which retrieves a range of messages from the
// POP3 mailbox and appends them to an EmailBundle.  The arguments are keepOnServer,
// headersOnly, numBodyLines, startIndex, endIndex, and the EmailBundle.  The indexes are
// zero-based and inclusive.

// Configure the POP3 server connection.
$mailman->MailHost = 'pop.example.com';
$mailman->MailPort = 995;
$mailman->PopSsl = true;

$mailman->PopPassword = 'myPassword';

// Fetch the first 5 messages (indexes 0 through 4), full bodies, leaving them on the server.
// keepOnServer=true, headersOnly=false (fetch the entire message).
// Note: numBodyLines only applies when headersOnly is true (it sets how many lines of the
// body to include along with the headers).  When headersOnly is false, the entire message
// is fetched and numBodyLines is ignored.
$bundle = new EmailBundle();

try {
    $mailman->FetchRange(true, false, 0, 0, 4, $bundle);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

$n = $bundle->MessageCount;
echo 'Fetched ', $n, " messages.\n";

$email = new Email();
for ($i = 0; $i < $n; $i++) {

    echo $email->Subject, "\n";
}

// Note: Explicitly connecting/authenticating is optional.  Chilkat MailMan automatically
// connects and authenticates -- using the property settings above -- whenever a server
// operation requires it.  Calling the explicit connect/authenticate methods can still be
// helpful to determine whether a failure occurs while connecting or while authenticating.
