Amber, I have been getting it since last night on about 200 different domains... I have well more than 1000 bounce notices, beyond the ones already deleted and such.
It sucks.
The spam is being bounced off of a DSL modem in Brazil. Then it ends up at:
http://sf1000.registeredsite.com/~us...ASS/index.html
This is the destination URL for that spam, which is hosting by registeredsite.com in Atlanta. I suggest a phone call to them to remind them how much you hate being at the end of a joe-job.
