Has something about sky/yahoo email changed recently? I've read the recent posts about filtering spam but I have found up to about a week ago my filter was working fine. My spam mainly consists of gambling, insurance quotes etc and all have been successfully removed. In fact I have found it to be sometimes a little too efficient, which is why I regularly check my spam folder just in case something important is in there.

About a week ago that changed and now the said emails are getting through!! Also when I move spam mail into the spam folder, I assumed the system would recognize any future emails of the same kind and junk it, but it still comes through.
What's changed??
