Earlier this week someone helped me lock down my ASA to only allow email traffic from a range of IP Addresses.  I am testing a service that GFI Mail Essentials provides.  They basically filter out virus and spam on emails.  The range of IP Addresses were GFI's.  Pior to the change I had Port 25 open to ANY.  I do not think I will continue to use GFI.  I will just be relying on ForeFront Security for Exchange.  From a security perspective and what is common, is Port 25 typically open to ANY at the Firewall?

Thanks -
