How to change the email FROM to user's domain, not mine?

Anybody knows how to set up DNS, postfix(centOS) or necessary others to make my email server send out email with custom domain in Email FROM field?

For example:

My mail server domain: @helloworld.com
Now the user will get my emails with From: [email protected]

But I want to have:
Users would get my email with FROM: [email protected]

Thanks a lot.

And we call this feature like “Custom Domain”. As I known, MailChimp is using this technology running their marking mail campaign, but I think it should be the core value of MailChimp, and I just want to know can we implement the same solution? Thanks.
