My sendmail knowledge is a little rusty; I've been using Postfix for a couple of years now. :) I think for your config.mc, something along the lines of OSTYPE(darwin)dnl DOMAIN(generic)dnl FEATURE(`nullclient', `mail.pointinspace.com') may do what you want. That is, _no_ mail will be delivered locally. When I ran sendmail, this is the config I used for my backup MX systems, and other systems where mail might be generated but never checked. Good luck. -- Cloyce
