No, what you describe is the spam protection from netzero or a lot of other free email services

Everyone who aquires a list of emails or scrapes the internet for emails has the emails saved, applied to their "email portfolio"...once they discover that an email they bought is "bounced" or stuff lke that...they just put tem in the cat. "bounced", not available...etc....and then they have after time another lsit what they sell for only 50% what they paid for......thta's just how it workks
