As the directions in the file itself state, fix situations like this with a simple whitelist. Given the number of hobbyist servers your MX will receive mail from, the whitelist will be very small and easily manageable. The ratio of hobbyist MTAs to spambots on a given residential subnet is going to be something like 1:5,000 give or take. The math speaks in favor of blocking the spambots and whitelisting the hobby MTAs. -- Stan
