Greetings!
In the past few weeks, I have noticed significant amounts of spam passing
through my filter. It is reaching a level that annoys me. I use
Spamassassin 3.1.7.
I used to get maybe one or two spam messages a day earlier this year with
200+ spams filtered. Now I get 10 to 20 spams per day that are not
automatically filtered (while something like 300+ are filtered.) Did
anybody else notice this? Are spammers becoming more effective in working
around SpamAssassin?
I examined the spam, and it seems that the majority of the messages score
BAYES_99 and nothing or hardly anything else. BAYES_99 is not enough to
filter the messages. I use the standard threshold of 5.
I have been tempted to increase the BAYES_99 score to 5. I have seen that
only very few ham messages of the newsletter type ever score BAYES_99 in my
inbox.
Do others make similar observations? How do you deal with this?
Thanks,
Michael
