Open Reputation System for Email

China Requires Registration of Email Servers

April Lorenzen (Outbound Index) — Sat, 15 Apr 2006 07:26:03 +1200

The oddly titled "China Outlaws Outlook" actually details news of a recent law enacted by China that would require outbound email server operators to register their IP addresses 20 days prior to beginning to use them.

Assumedly, the Chinese government will offer an IP DNSWL (DNS White List) of registered servers and inbound mail server operators worldwide would have the option of rejecting mail from any other IP in China.

This may not occur, if the rest of the world becomes concerned about censorship issues. For example, what if the Governor of each US state selected which outbound email servers could operate from within his state, or the Senate Majority Leader could specify what American IP addresses could send outgoing mail.

From a fear / punishment and censorship perspective, the provision in the new Chinese law that requires mail server operators to keep a record of all mail incoming and outgoing for 60 days is in my opinion pretty significant.

The service sorts e-mail based on factors such as domain age, relationships between server and domain, and sender stability."
