ucla.edu have the perfect policy. |

I refuse point blank to accept any mail whatsoever from dynamic ranges or |
| 13 |
insane reverse lookups. |

Why? Because doing so immediately gets rid of 1,000,000+ spam messages PER |
| 16 |
DAY. |

Yes, you read that right - a million spams each and every day. The number of |
| 19 |
users with other ISPs that have valid reasons to host MTAs on DSL is tiny in |
| 20 |
comparison and they can relay through their ISP (or get a different one that |
| 21 |
understands mail). Do you have any idea how much that bandwidth costs in a |
| 22 |
third world country? Or the spam cluster to deal with it? |

Management agree with that sentiment. Although they did raise an eyebrow a |
| 25 |
year ago when a colleague blocked ALL of China. They asked him nicely to |
| 26 |
narrow things down a bit to actual offenders :-) |
