no. you can't stop the other end from sending you mail. If the rate of sending is great enough, you'll be DoS'ed. It could go on for days or weeks, or months, the latterin one actual case I know of an Imail system in TN. The best you can do is put IMGate out front, and hope that the attack is coming from ip's that are in RBL servers. Even then, the rate of attack could consume all the SMTPD processes on IMGate (I've seen an attack from 1000's of open relays world-wide consume 400 SMTPD processes). If the attack is from a single ip, a small group of ipss, or subnets, you could block at the ip level at your edge router.
