block their ip addresses using iptables, ipchains, or ipfw.

also, postfix by default does not allow foreign relaying... maybe it's people sending you messages, or someone faked headers so you get tons of returned emails (somewhat like a smurf attack but using email..) not sure. would have to see.

hit me up on icq if you want my help looking into it..
