Spam filtering at the ISP or Hosting level means emails blocked will never have a chance to be reviewed. This is very bad because no spam filter is even 80% accurate as of now. The best way to filter spam is in the program you use, the great part of this is you can still access the emails marked as spam in the spam folder.
Our favorite email program is the free Thunderbird by Mozilla. You can download it here for free: ThunderBird
