What exactly does genericstable do? (Sorry, writing this mail off-line)

But it isn't right? newsguy.com isn't a valid Domain Name is it??
I'm not sure if your solution is a viable solution to my problem.
My Problem.
@work = mails must be sent out using the corp exhange server (smart host
feature _must_ be implemented via sendmail.mc)
@home = mails are sent out w/o using smart host. Meaning, I have to
actively re-compile sendmail.mc each time between office and home to
send out emails. Cause @home, mails gets relayed directly to the
receipient's MX.

Just as I thought. And what/how does this affect mail sending?

What does this achieve? I don't see a genericstable in my

What's data format error? And I see that your relay is =
smtp.newsguy.com, which resolves to your Inet Public IP.
For my case, it gets relayed to the localhost (127.0.0.1)'s smtp. which
then hands it over to sendmail to contact the MX.
What I want to know is, is there a way to say that I want mails to be
sent out 1st using the Direct approach, if it fails then fall back to
the smart host.
Something like /etc/host.conf
user$ cat host.conf
order hosts,bind
pseudo code :
if [check if it's a local address ]; then
pass to local sendmail
elif [check if we can send direct to MX ]
pass to sendmail for direct MX
else # when all else fails
pass to smart host for relay
