Mail.app under 10.4 always requires confirmation when first opening a connection to a server with a self-signed certificate - even though I have the certificate in my x509Ancestors KeyChain and have set it to always trust there, it just won't accept it directly. Does anyone have an idea how to get Mail.app to stop this nonsense? It's only when starting Mail.app, later when disconnecting and reconnecting it doesn't happen, but it's still annoying... The message always says "This certificate has no root certificate" - which makes sense, as it only signs itself. Somehow this is quite stupid - instead of simply believing "Always Trust" Apple thinks it knows better. I hate know-it-all software.
