I have also seen this happen when the response is slow from the mail server to show the 220 message. It does show it but is slow for some reason. I create a new service called smtp-slow by adding the following and then configure the bb-hosts entry with 'smtp-slow' instead of smtp. Just a thought.
This way it doesn't require a 220 response but if it gets a valid "connection" it is okay. If it can't open a connection, it goes red. It does limit the amount of app validation but it is the only thing that worked in my case.
[smtp-slow] send "mail\r\nquit\r\n" options banner port 25

As it happens, there are PIXs between the hobbit server & all the Exchange servers. However, they've all been there for ages (years in some cases).
I'll have a chat with our resident Cisco guru & see if he made any changes at our end around 6th June, when things stopped working.

You wouldn't happen to have a Cisco PIX/ASA between the hobbit host and the mail server, with it configured to do "fixup"? Those are known for breaking things ;)
