In order to protect our subscribers from spam and viruses, Mediacom Online has implemented some new features to the e-mail servers. 1. Any incoming email with more than 500 recipients will be rejected. 2. Any attachments of .exe files will not be permitted. 3. Any customer sending excessive amounts (thousands) of e-mails, may have e-mail access blocked. Spam is not permitted in accordance with our AUP. If you have any questions, feel free to contact your local office here.
