[Discussion list for OpenIndiana]

It works this way.  

sender at yahoo.com posts to the list.  The mailing list package forwards the post to all the subscribers. Everyone on the list EXCEPT the subscribers using yahoo.com will see the post.  yahoo.com will reject the message as a forgery, so no one using yahoo.com will see the message.  It's not clear to me if user at yahoo.com will be unsubscribed because of the bounces or just sender at yahoo.com.  It seems likely that a malicious person could unsubscribe all yahoo users from a list by creating a yahoo account and posting to the list a bunch of times.

In all cases, the mailing list gets the post.  It's what happens next that poses the problem.

 Sorry, but you misread: I
 am asking about other *mailing lists*.
 
 They, the *mailing lists*, are receiving email
 from @Yahoo users.
 
 How?
