My ISP (virgin media) enable you to set "rules" on how you want them to deal with spam - send it on to you marked "spam" for you to deal with, hold it all on the server in the "spam" folder or other combinations. Anything in the spam folder is automatically deleted from the server after 30 days so I don't even have to see it, although I do log on to check that something has not gone into spam accidentally - where I can also "teach" the server that that particular email is not spam and should be ignored. Presumably Talk Talk have a similar situation.
