Let me see if I understand the white list. Let's assume that I have a domain name 'xyz.com' in my white list. If a spammer puts 'abc@xyz.com' as his FROM and sends this email to me, the Spam Filter will allow it to go through, right?

Then what's the point to have this function? Anybody can fake it. For example, I could just use 'abc@microsoft.com' as my return email address, and your SpamFilter would not catch it if I have microsoft.com in my white list. Who doesn't? |

The advantage of having a domain whitelist is so you can allow emails from a domain that keeps appearing in an RBL. A spammer can't take advantage of this unless they know what your domain whitelist looks like. Obviously, you'd want to keep this list to a minimum. Instead of complaining about it, don't use it. Just because you don't understand a particular feature does not mean it is not useful. LogSat implements most of its users' suggestions and is one of the most responsive vendors I have ever worked with. Bill |

I sort of figure out how to use this feature. It's best to use it in combination of 'Reject if no reverse DNS'. I happen to have lots customers not having any reverse DNS. It's a good idea to add them into white list, but leave those who have reverse DNS out of the list. This way I can minimize my list. |

You've just found one of the main uses of the whitelists. If you need to receive emails from a particular domain that for some reason is blocked, the whitelists will help you with that. Roberto F. |
