Personally, I find this anti-spam scheme from uol worst than spam
itself. Its the isp trying to babysitter the user with a 'feature'
that annoy other people, and won´t let the user learn the basics of
filtering messages with real features inside his mail client. Not to
mention the unnecessary increase in traffic.
I also receive the petsupermarket bounce. I created a filter.
