Why do some messages say that they're to "invalid" or someone at SPAMSteward.com?

Our software requires a "To:" header in email messages to be processed properly. Because some messages sent to lists or via carbon copy won't have this header, our software will add one containing either youremail@spamh.com or INVALID. This is normal and just means that the email message was missing a "To:" header when we processed it.
