Just wondering if you could help.

Background:
We have 2 companies CompanyA and CompanyB and they are both on separate domains and cant be joined, as our head office (CompanyA) is using Windows Essentials Business Server. CompanyB does not have Exchange as they are only small so we host them on at CompanyA.

Problem
At companyB we have Sharp Printer that also sends emails as PDF. What i did on exchange 2003 was just accept any mail trying to be sent by CompanyB External IP address.

Now how do you do this with Exchange 2007

In 2007 you can allow relay for a specific IP address such as the PDF printer
have a look at:
