A nit to pick... On linux glibc and solaris, you don't use '/etc/hosts', you use whatever libnss_* module /etc/nsswitch tells you to use.. This means you can have a large network of machines which are managed by Ldap or NIS that don't ever hit DNS for local lookups. Now, I admit smtp servers are 'special', but you *are* breaking several assumptions most people expect by not using the OS provided nss lookups. And yes, I deal with around 200 odd hosts that still use /etc/hosts lookups.. they are the compute nodes for a couple of 32-64 node clusters. It's not *that* big a deal since the cluster nodes are identical. But I am looking at either libnss_ldap, or running a ldap->bind dns server. The ldap->bind->dns route DOES have several disadvantages, most notably convincing it to update quickly when you make an ldap change. -- -------------------------------------------------------------------------- Troy Benjegerdes 'da hozer' [EMAIL PROTECTED] Somone asked my why I work on this free (http://www.fsf.org/philosophy/) software stuff and not get a real job.
