I'm not sure this is possible, the way postfix is configured is when it recieves a message it automatically sends it the content filter where it is processed by ClamAV and SpamAssassin. Then it is sent back to postfix where it is delievered to the appropriate mailbox via LMTP.
I have no idea if this is possible, but my only thought would be to put the TO address on a whitelist. The cavet being whitelists are meant for FROM addresses. |
