Adding Exchange Defender for SMTP Security

A price we pay for putting ISA on the same physical box as our Exchange server in SBS 2003 is that we're unable to make use of the SMTP features in ISA. You can however use Exchange Defender, a third party SMTP filtering service, to reduce incoming spam. (among other nice features) If you are planning to implement Exchange Defender you'll want to have a look at Susan Bradley's article on how to configure ISA to work with it. You can find it here. I'll add this reference to the App section on the blog website as well.
