The exchange server administator should be able to provide you another
port (mostly they use 2525/tcp) for checking the recipient via a SMTP
call-forward
I don't know the very details, but if I was pushing them enough, they
were able to find the settings they've to change :)
Then you can use specialized router/transport combo for recipient
verification only.
