Did anyone know or can provide some instructions on how to setup smtp
for sendmail.

All I need to do is email files from sco thru my ISP smtp provider.

run
#mkdev cf

Make sure that you have a default gateway to the internet, and DNS, and a reverse DNS entry.

I did that.
But where do I set my SMTP settings? I am using my ISP's SMTP that require authorization

You can do what you want with MMDF instead of Sendmail.
Remove sendmail using custom, and install mmdf.
If you haven't done that before, you need to expand the "SCO Unix Enterprise" line until you find sendmail.
