Why would you want to accept the message and them process it? Keep using chkuser to reject at the smtp level for "no such users" and setup simscan to query spamassassin / clamav and also reject virus/spam at the smtp level as well. This way the responsibility is back on the sending server and not yours and they, not you will be likely to hit a spam trap and end up in places such as SORBS, SPEWS and Spamcop etc. Just my two cents worth, but is also how we do it and it works very well.
