Wed Feb 14 10:22:39 PST 2001 — Attack on mail servers. Our entire mail server array has been impacted by what appears to be either a) a rude or misconfigured mail host, or b) a denial of service attack. We decided to treat the situation like an attack, isolate the source, block the attack, and then harden our servers to prevent future attacks of this nature. We have completed all but the latter step, which pends further analysis. -Scott, Steve, Kelsey, and Russ
