Re: [Exim] Kool Spam Catching Trick

The reason for sending defer is because the spam will never arrive at
all that way? Because those who use that trick will not email to the
primary .... I like it!

That's a good idea for most people. In my case I want to actually
accepts the spam - bayes learn it - report it to Razor - and then bounce
it as an non existent address.

But - your idea of just having secondarys that do DEFER is definitely
interesting.

hmmmmmmm .......
