Well I consider the search filter by subject is a much better approach,
for participating on a conversation.

people out there (yahoo) not liking a service (list) that impersonates someone else.

If the list sends a properly crafted e-mail coming from its own address and domain
why do you think would be a problem?

We should stop for a sec and think if what yahoo did was good or not to fight
spammers; I think it was good. A list that impersonates a sender is not a good approach.

Sure; I think we should adapt to this new situation.
