Thanks for the reply Bruce, and thank you for the welcome.
After setting Spam Assassin back to the recommended setting I found out it was working, it is just that it was not tagging many emails as Spam, and that is with a setting of 5.
Trying to consider my alternatives here, one is to enhance the blacklist addresses which would be a never ending job as these spammers keep changing their addresses, second would be to try increasing the amount of spam caught by lowering the total hits to a 3 or a 4. More good emails may be tagged, but I can always whitelist them. I have it all going to a SPAM mailbox on my PC so I can monitor it all.
How does Spam Assassin "learn" what to tag and what not to? Is it from the blacklist/whitelist I set up? Currently it lets a lot through.
Thanks for the help.
