It really is, unless the account is being deluged with spam. > as there are many tests that your SA can't do that a mail server can > do. There are a few tests that SA can't do, but SA can do some of them a lot better. Mail servers have a huge handicap in that they mostly work in real time. A polling delay and not testing 24/7 can make a huge difference. On the list we see people reporting difficult spams that have huge scores on retesting. It's not necessarily true that an ISP with poor spam filtering is failing to do server-side filtering. It may be just skimping on expensive content-filtering, but still doing the cheap tests that save resources. This is an ideal case for client-side filtering.
