this is the first time you've seen this? it's been going on for years. I don't know how spammers work, they probably work in 100's of different ways, but the @recpient.domain is in a database shared by many spammers, via address cdrom's, etc, etc. And the older a domain, the more likely the volume of spam will be greater. the sender@ and recipient@ are forged using some other database, the combinations are infinite. Imail nobody@ allows spammers to deliver, which is how they get paid, so they will re-use a nobody@ domain to run up their delivery numbers. nobody@ is totally insane. Len
