Look up the IP address in a database. If they don't have a database,
perform a reverse DNS lookup and reject anything which looks like a
typical auto-generated name for a consumer DSL/cable connection.
FWIW, I've been running sendmail on my home system (ADSL with static IP)
for years, and have had very few problems with mail being rejected.
