Another tactic is to put everything from aim.com on postfix HOLD, then check it every couple hours and manually delete the spam, and release the legit, while threatening aim.com to block everything until they fix their problem.
postcat to look at the hold/ dir msgs postsuper -d queue_id to delete a spam "postsuper -H ALL" to release the non-deleted legit. You might also note the recipients of legit aim.com mail and email them that aim.com is at risk of being blocked totally for spamming, in the hope that your recipients will notify their aim.com senders to complain to aim.com.
