How to disable catch-all on Exchange 2007\2010

Hi,

can anyone tell me please how can I disable catch-all on Exchange 2007 and Exchange 2010?
Both systems don't have Edge servers there, only HUB.

Thank you

There is no catch all by default in Exchange.
However by default Exchange will accept email for all recipients. To stop it doing that you need to install the antispam agents, then enable recipient filtering.

Thanks,
Weird part is that I don't have any dedicated transport agent for catch-all, but still when I'm trying to send email to non-existing users from telnet, I get prompt that Recipient is OK
