Why is MS doing spam checks first?

> This old chestnut...

Hi, we had a different scenario with the latest Sober outbreak the other day. People got 'bounces' due to non-allowed file-extention 
(.exe).

a) They got a message bounced, but the 'From' was offcourse fake.
b) The (incorrect) bounce contained a virus because it was not yet scanned.

Usually this does not occur because messages are virus scanned on our edge smtp relay's before hitting the spam/attachment relay's. 
But due to some timing constraint the edge relay's AV-engine's did not yet recognise the 'new' virus ....

I know it has been discussed over and over .. and (having read the source some time ago ... ) I know it's a mayor switch, but 
it -is- viable for some to have an other priority in which order scanning, bouncing on illegal attachment etc is done .....

bye,
Chris
