# ------------------------------------------------------------------------
# The FetchSingleHeaderByUidl method is deprecated:

# emailObj is a Email
$emailObj = $mailman->FetchSingleHeaderByUidl($numBodyLines,$uidl);
if ($mailman->get_LastMethodSuccess() == 0) {
    print $mailman->lastErrorText() . "\r\n";

# ------------------------------------------------------------------------
# Do the equivalent using FetchByUidl.
# Your application creates a new, empty Email object which is passed 
# in the last argument and filled upon success.
