Setting Exchange to receive email from spam filter only
Posted on 2010-08-20
We just setup an Exchange 2010 server. Right now we only have it setup internally and it will except emails without authentication. We have a Barracuda spam filter and we would like the Exchange server to only accept emails from the spam filter's IP. For phones and device that send email to the server, we would like the Exchange server to require authentication. How would I go about doing this?
