sending mail out (only)

[William L Anderson <band@acm.org>]

I've gotten OpenBSD to boot up into a VMware partition, and I'd like
to be able to send mail out from there.

However, I'm having trouble configuring either sendmail or exim to
produce a legal outgoing address; it always produces
  root@sigmund.localdomain

I'd like to force this to be my real ISP email address.

Also, resolv.conf seems to be regenerated at boot time. How can I
manually set domain and nameservers?

I've spent a lot of time w/ my sendmail book, faqs and other net
resources, but I'd be happy to follow up any other useful
documentation that is suggested.

TIA,
Bill Anderson
