I sort of expected that to be the case. That's why I asked the follow up
question.

I'll have to see if I can get away with that. I'm not that concerned with
the bandwidth. Much of the spam comes in over night when our BFPs (Big
Fat Pipes) are idle.

That's what I want to do. I hate the idea of accepting mail and then
remailing it and creating the bounce if it is spam. I'd much rather issue
the tempfail to someone else's server.
