Hi,
I am looking for a bit of advice or maybe just reassurance.
I've been running with SBS 2003 and now I am on SBS 2011 standard but I am not completely convinced I have the best setup regarding email.
I have always been worried about connecting Exchange directly to the internet, so I've always had another email server in front of it, on a separate box, which forwards email on to the Exchange server running on my SBS 2011 box.
The thinking behind that was that if the other mail server running on a Windows XP box got compromised it wasn't the end of the world as it could be wiped and re-installed fairly easily but if my SBS box got compromised then that would be a bigger issue.
I am also looking at using one of the many hosted anti-spam solutions, they seem to be worth wile as they offer me SMTP redundancy as well as being able to only open my Exchange server to their IP addresses only.
