RE: [nznog] backscatter attack

Quoting Spencer Stapleton :

Neither will be trivial for us to implement (other than exporting our own SPF TXT records IN DNS), and will require the installation of OpenLDAP (which will admitedly be useful for 101 other things) as well as upgrading all our MTAs.

I think you'll find taking the time to learn how LDAP works and the implementation of it to be rather useful in the long run. As you (and Simon, earlier) say, it can be used for a range of other things. Flat files be gone! There are some great resources on the interweb as to where to start. Cheers Michael
