Having received notice about the impending service change, I have decided to stop using spamcop to read my emails for filtering. HOWEVER, I have looked and looked for an account option to tell spamcop to stop accessing my email, so I can get another provider to do it - I can't find such an option!!
Any ideas how to stop spamcop from accessing my email, and switch off their service?
Getting a subscription refund will be next.
