Answer 1

You need to use the CatchAllAgent on CodePlex. This was written to work with Exchange 2007 but it does work with 2010 as well.

The key trick is to install it in the TransportRoles directory as per these links:

http://catchallagent.codeplex.com/discussions/218519?ProjectName=catchallagent

1) download the ZIP

2) unzip to "C:\Program Files\Microsoft\Exchange Server\TransportRoles\agents\catchall" [or wherever the TransportRoles\agents path is]

3) Edit the config.xml file in this directory to define the domains to be handled

4) Run Exchange Management Shell end execute these commands:

install-transportagent -Name "CatchAll Agent" -TransportAgentFactory:CatchAll.CatchAllFactory -AssemblyPath:"C:\Program Files\Microsoft\Exchange Server\TransportRoles\agents\catchall\CatchAllAgent.dll"

get-transportagent

enable-transportagent "CatchAll Agent"

net stop MSExchangeTransport

net start MSExchangeTransport

5) Send some test mails to see if it works!
