Does anyone have a .mc file kicking around for sendmail that creates a forwarding only server? I'd basically like to set up an OpenBSD 3.3 firewall box running the new spamd, and a sendmail daemon that basically forwards all mail received onto our internal mail server.

I know I could write a pf rule that would forward port 25 to our internal mail server, but I like the chroot sendmail on OpenBSD, and would prefer to have it exposed to the big, bad innurnet.
