We give list owners the option of blocking all email arriving from 
the outside Internet. The majority, having only subscribers inside 
the College, choose to do this. This is implemented by a custom rule 
at our spam filtering provider, Proofpoint.

We have found this technique to be essentially 100% effective for 
those lists. Subscribers who insist on forwarding their email to an 
outside ISP can still post to lists using our internal email web 
client via the Portal. Some don't like that, but they don't like spam either.
