New spam record
As I described in a previous post when talking about spam countermeasures on one of our servers, misbehaving mail senders are locked down using fail2ban for a certain amount of time.
Today, we got two new records in our internal spammer high score:
Banned services with Fail2Ban: Bans:Unbans
Exim4: [243:241]
202.109.98.37 (chipolbrok.com.cn) 9:10
122.55.96.50 (122.55.96.50.pldt.net) 7:8
Those two hosts in China and the Phillipines have been behaving most rowdily so far.
And, in addition, I cannot verify that the spam situation improved after one of the major botnet control hosters was taken down. Quite the contrary. We saw a small decrease for a few days but the average number of spam/malware per day that someone is trying to load off at our server has more than doubled compared to the situation two, three weeks ago. 
We totally need to make some (public) graphs, for spam vs. ham, bans/unbans a day, and similar data. That’d be interesting to see.
