as part of a migration scenario we need to be able to receive mails on our local Exchange 2010 SP1 server as well as forward all incoming mail to an external host (even if mail is succesfully delivered on local server). Is there a way to do this in Exchange 2010 or do I need to set up another SMTP server in front which can send incoming emails to two different hosts?

I believe this is what you need:

You can journal all the inbound emails to another account. We use this for echoing all emails back to postini for archiving. I don't know if this will work for you as it will echo everything and its done at the database level.
