[-- Attachment #1 --] Hi Dan, Thanks for the reply. Yes, I believe that your advice sounds pretty logical for my situation here. I could indeed run a caching nameserver on my local net, and configure sendmail afterwards. One further question though, would it be possible / prudent to run bind for this purpose chrooted? I browsing the handbook, its pretty obvious that some measure of securing bind might well be warranted. Thanks again for your time.
