Ah, yes, the old trick of relying on users to correctly identify phish :) Unfortunately this rarely works well in practice. If the email looks good (e.g., the spammer just copies a legitimate message and replaces the login link with a phishing site) then most people typically don't notice that the URL is a phishing site. Some users even dig these out of their spam folder, even though the message has a big red banner at the top. In any case, a non-default setting is not going to solve the problem of senders from highly-phished domains to communicate with gmail and yahoo users through mailman. How would the list members even know to change this setting?
