We use Exim mail gateways to do the virus/spam checking, which then feed into internal-only Exchange servers (amongst other servers, depending on where a users mailbox is). This setup works well. You may need an internal-only domain for mail routing within Exchange, which will need to be rewritten on the way out by the Exim servers. I guess if you only have one internal Exchange infrastructure, you might be able to do without this.
