It's my experience that it's not always -- or even mostly -- that ISPs have changed the names, but that users change mail programs (for instance, start using Netscape Mail) and inadvertently change the return address when they configure it. And I don't see how the ALIASES NAMES list will help with this, since, I assume, you have to know the address has been changed and add it to the list manually. What usually happens on my lists is that someone suddenly discovers she's unable to post (or, more likely, unable to unsubscribe) from the invisibly altered address. -- Russ __|~_ Russell A.
