Sorry, you did not "try all things on net".
If you'd like help, what version/distro of Linux are you using? Also, there are MANY simple, step-by-step how-tos that you can find on Google for setting up both sendmail and postfix. They have examples, and walk you through the whole process. We're not going to reproduce those guides here, and you've really given us no information to work with.
Check those guides, put together a config, and test it. If it's still failing, come back with a *SPECIFIC*
error/problem, don't just ask us to configure your sendmail server for you. Hint: if your Windows server is the relay for all your mail, you need to define that as your smarthost.
