Is it just us or does someone pWn *.amazonaws.com? Every one of our mail servers is being slammed by I'm not sure what but many thousands of user unknowns per hour (fortunately we handle those pretty quickly but this is a deluge.) All I know is "amazonaws.com" is "Amazon Web Services", not sure if these particular systems should be sending email at all, the hostnames look like: ec2-67-202-36-134.compute-1.amazonaws.com ec2-67-202-37-35.compute-1.amazonaws.com ec2-67-202-37-38.compute-1.amazonaws.com ec2-67-202-38-112.compute-1.amazonaws.com ec2-67-202-39-87.compute-1.amazonaws.com ec2-67-202-8-122.compute-1.amazonaws.com ec2-72-44-37-77.compute-1.amazonaws.com ec2-75-101-192-20.compute-1.amazonaws.com ec2-75-101-202-130.compute-1.amazonaws.com ec2-75-101-207-190.compute-1.amazonaws.com ec2-75-101-210-120.compute-1.amazonaws.com ec2-75-101-224-146.compute-1.amazonaws.com ec2-75-101-227-187.compute-1.amazonaws.com ec2-75-101-228-221.compute-1.amazonaws.com ec2-75-101-229-15.compute-1.amazonaws.com ec2-75-101-230-147.compute-1.amazonaws.com ec2-75-101-234-192.compute-1.amazonaws.com ec2-75-101-236-135.compute-1.amazonaws.com ec2-75-101-238-69.compute-1.amazonaws.com ec2-75-101-241-105.compute-1.amazonaws.com Those don't look like mail servers but what do I know? Anyhow, if there's anyone awake at Amazonaws.com, your hair is on fire. -b
