That's what I use here although currently less than 100/day for two nearly 7yr old domains. SMTP-MaxErrors "2" SMTP-RDNSCheck "-2" Also IP blocks that send me lots of spam get put in spammers.tab with "code=-3" which then gets increased if spam continues. I've noticed some legitimate sites I've tested this with have problems with long delays so longest I've used is 7 seconds.
