Re: eCircle has been trying to send me spam for a decade or so.
It isn't crap that eCircle is sending - they manage a weekly newsletter for Zopa, which I invest in.
I can see why my ISP has to stop spam, but they are deleting mail without so much as a notification to me. In addition, their reasons for doing so are often weak - they use advisory blacklists for blocking, even when the blacklist provider recommends not doing so!
I'll be changing ISP as soon as I can manage it. I am trialling Google at the moment. I might even run my own mail server.
