Header Checks: Examples of What Not to Do
Posted by mike Filed Under Filters with Comments Off
Listed here are a number of header checks that do work but they are ineffective for the most part. Here is the problem. When you look at these examples they have a Subject that you are searching for. As a result you will be writing header checks until the day you die, not good. My thinking is that you will want to discard this methodology for header checks that are more general and throw a wider net over the problem. Two reason for this are; first you have SpamAssassin or some other program to do actual Spam testing later. Second, you need to preserver resources on your Postfix mail server. Actually this is the most important aspect of what you are doing is trying to save yourself money and time by reducing the load on your server. If you place too many header checks in Postfix you will begin to see a speed loss and resource loss.
So review your header checks and make sure you are using each line wisely.
