I have exchange 2007 on 2008 R2. I run sophos puremessage that won't install on R2 until the end of June.
I installed iis smtp on a windows 2003 server and installed puremessage on this box.
Now, how do I tell exchange 2007 to use this smtp server on the 2003 box for incoming email? I will continue to push email out of the exchange 2007 server and not worry about filtering outgoing email for now.
Thanks for your help.
