TWC Mail has detected an unusually large volume of email coming from your TWC Mail account, probably due to a virus on your computer. In an effort to protect customers and the rest of the Internet from spam coming from the TWC Mail network, we have temporarily (for the next 24 hours) limited your ability to send mail via TWC’s mail servers. If you attempt to send any email during this time you’ll receive the message above.
If, after 24 hours, your ability to send email is not restored, contact us.
