I am not sure this belongs here but it was an issue for us. In using Symantec's Mail Security for SPAM and AV scanning we implemented the DNSBL function. Worked great until the evening 8/26. Turns out that all of our Exchange server thought everyone was spam site including each other. Turns out that the list manager was under DDoS instead of just shutting down he turned the list against the all IP addresses. This demonstrates that even those you trust can shut down your services in ways you would least expect it.
Reply from SPAMCOP when I asked them what they knew about the situation.
Because of ongoing problems with DDoS against Osirusoft, as well as many
other anti-spam sites including SpamCop, Spamhaus and monkeys.com, Joe had
to pull the plug as he just didn't have the time or resources to battle
back. Unfortunately he did something really stupid, in that he listed the
entire Internet along with a text message of "Stop using Osirusoft.com".
This means that anyone still using Osirusoft is bouncing/tagging/devnulling
all mail coming into their systems. Why Joe chose this route no one is
really sure, but it has lead to a lot of pissed of people and a lot of
Follow his advice, stop using Osirusoft.
