Just a question. Has anyone notice a sever increase in spam over the past week. Our connections which have been normally 10 a minute have increased to 100-1000 a min. Sometimes to the point where Spamfilterisp will recieve Socket errors and have to be restarted. A majority of the emails have a <> "Blank" From Email (over 240,000 a night). I usually block if no From Email is listed, but had to set it to quarantine to help lower the traffic, as the source continues to try if rejected. Just thought I would toss this out there. Looks though as if someone is a little upset we have a spam filter and are trying intentionally a DoS.

sounds as if you're targeted. no increase here , but we're just a small company.

Shouldn't the IP Cache blacklist stop this?

If they have a whole slew of zombies at their disposal they could rotate them through during the attack. It helps to use AuthorizedTo list expecially if its a dictionary attack.

All unique IPs, I'm sure they are forged. It is an unique attack.

They can't (easily) forge the final IP just when SFI receives it. Maybe there is something common in the contect itself that can be blocked or is it just various spam messages?
