I got this email from another.com, which allows you to have an extra nine email addresses that are aliases of the main account one. I had “email@example.com”, or something very similar. I'd almost forgotten about it, in fact, until this came.
We write with reference to the alias email address you have @heathrow-airport.co.uk
Following a complaint from the BAA, we have to withdraw this domain name from the service within the next 7 days. Any emails sent to your address at the domain name after this date will be returned to the sender.
Any other alias will be totally unaffected and your account will continue to operate normally in all other respects.
Please accept our apologies for any convenience that this may cause.
