Postfix and ASSP in different machines

Hi All

I have a box with Postfix+ClamAV+SpamAssassin in the same box. Mails flows nicely, but SpamAssassin isn't doing its job as desired.

I would like to experiment another solution with ASSP.

Can anyone tell me how I can have ASSP+ClamSMTP+ClamAV in one box, and Postfix in other? The idea is to have the e-mails scanned for spam and virus in the first machine and then redirected to the second one which has Postfix. On the sending side I would like the e-mails go out of Postfix box towards the one with ASSP+ClamSMTP+ClamAV and this would be responsible for the sending processes. I would not need to check for spam and virus when sending.

Can anyone help? I am such a "rookie" in Linux.

Thanks in advance.
