Folks,

Just FYI more than anything, we're seeing the second bounce message
backscatter attack targeted at our abuse@ mailbox in 12 hours.

Someone sending what looks like old spams out with a From: line of our
abuse role account, evidently intended to joe-job or cause nuisance to
people monitoring that here.

Not massive in terms of rate, about 20 per minute, but it will probably get
annoying if these keep coming in for more than about 5-10 mins. We already
correctly recognise them as bounces and don't open cases for them anyway.

Wondered if anyone else is seeing an increase in rate of this sort of thing?

Mike
