BT Internet and spam filters-Why?

[Orionaut]

Why is it that while BTinternets automatic e-mail spam filters are reasonably good at blocking the more obvious items of spam and malware.

The one thing they dont seen to be able to block are the (relatively convincing looking for the uninitiated) phishing e-mails that try to scare people into responding to them by claiming that their e-mail accounts are about to be closed?

Because they haven't seriously tried, because most people don't use their bundled email account.
Use gmail, or fastmail, etc.
