The only major concern is forgeries from people in the domain.<BR/><BR/>So, I think the original idea is still valid. It might be useful to whitelist people with high reputation in a domain with a medium reputation.Greg Lindenhttps://www.blogger.com/profile/09216403000599463072noreply@blogger.comtag:blogger.com,1999:blog-6569681.post-1169918457252143082007-01-27T09:20:00.000-08:002007-01-27T09:20:00.000-08:00Great point, Anonymous.

Preventing that would require solving the sender id problem.<BR/><BR/>You are right, probably not a great solution then.
