It wouldn't be a good idea to shift DNS away from the email server - much of what an MTA does is DNS lookups, so it is always a good idea to have a fast, caching name server on the local machine. Better throughput through better latency. Caching (or authoritative, for that matter, on an unbusy domain) DNS isn't a horribly expensive process. - Jeff -- linux.conf.au 2004: Adelaide, Australia http://lca2004.linux.org.au/ "Stick to your guns and get it right." - Havoc Pennington -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
