I have recently understood AWL better, and am wondering if there should be some minimum number of entries before AWL is applied. I often get spam that doesn't score that high due to being a fresh relay. If I rescore it with '|spamassassin -t' after a few days, often it's on blacklists and scores a lot higher, but is pulled down by AWL.
So, I wonder if a rule that said 'AWL is only applied if there are >=5 scores in the average' would avoid giving credit for spam that arrived when it wasn't classified as high as it should be now.
