lots of new spam

[Payal Rathod]

Hi,
>From 4-5 days I have been receiving a lot of spams, 100s of them with 
weird subjects like, Re: a f news 141, Re: K R news 721, Re: B l news 
203 etc.
I have with bayes learned alteast 200 of them, but they are still pouring in.
Any ideas on their blocking?
With warm regards,
-Payal
