In comes an email from a Czech email address (Bruno.Sopko@fs.cvut.cz), as follows:

"Your mailbox has exceeded its storage limit of 1 GB, which is defined by the administrator, is running at 5.9GB, you may not be able to send or receive new messages until re-confirm your inbox. For revalidation your inbox

On reflection, maybe I won't send them my details.
