This may not work for you, but I solved all my yahoo problems by simply blocking their servers with a nice message about over a billion accounts being leaked. But yahoo was less than 1% of my traffic (and most of that was spam or at least unwanted email). The only things I get “from” Yahoo anymore are list messages. -- Apple broke AppleScripting signatures in Mail.app, so no random signatures.
