We just upgraded from Win SBS 2003/Exchange 2003 to Win 2008 R2/Exchange 2010. All is working well, except the spam is now over whelming. Before all the Outlook clients took care of most of the spam, plus we had Ninja in front of the Exchange Server.
I'd like to use the built-in Spam that comes with either Exchange and/or Edge. We did install the edge role on the same server, but I've read a few things that make me wonder if that's a good idea. If anyone can summarize a "simple" solution for me I'd be grateful.
One other note, it appears that the built-in spam in Exchange is filtering out some spam. But some of what it is filtering out isn't spam. So how to control that?
