It is not just MS's smtp server, older sendmail versions will also trigger false alerts also. I got a Solaris 2.6 running very old version of sendmail and keep triggering false alerts. In the end, I gave up on monitoring that particular sendmail server.

We had a similar problem with our exchange server until I changed the bb-services file to be:
[smtp]
send "helo\r\nquit\r\n"
expect "220"
options banner
port 25
Now the exchange response to smtp is much more stable, but my linux sendmail servers complain more often. I guess I need to make a smtpex with the above and restore the original smtp definition, which seemed to work better with Linux. Why can't MS just do things to standards?

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 ;)
