Exchange drop support for SMTP?

I want to send email with Exchange by using telnet to port 25. Until two week ago I was able to, but now a "security fix" from Microsoft has removed this possibility.

When I try, I get this message:

421 4.3.2 Service not available, closing transmission channel

What can I do?

    Thanks for your help!

    Basically, this functionality was removed by default and it could be restored by means of an ad hoc configuration - but with no guarrantee that further "updates" break the system again. Thanks, Microsoft.
