Best documentation to setup sendmail

We just install Oracle Enterprise Linux 5 (Based on redhat), and i was wondering what would be the best way to setup sendmail. I have an SMTP server that i can send the mail to but would need help with documentation on how to properly setup sendmail.

Re: Best documentation to setup sendmail

Your configuration seems fairly typical so far. The links given by Michel can give you some quick answers.

But if you truly want to understand sendmail, you'll eventually need the canonical "sendmail" book from O'Reilly.

It's a big and scary-looking book, but the bulk of it is reference chapters for all sendmail's details. You'll want to read the (very good) non-reference chapters in the beginning first, then pick and choose what you need from the reference chapters.

Reading through the entire sendmail book (latest edition) from cover to cover is the stuff of aspiring Sendmail gurus and rainmen, not for mere mortals... unless you need a cure for insomnia :)

I think is the best documentation.

I learned everything I know about sendmail from that and the O'Reilly book.

I can make sendmail practically make coffee for me if I want. I have a custom configuration building script that totally knocks out abuse spam relay. I can even make a configuration that limits send domains, with a little help from iptables firewall.

It took time to learn it.

If you simply want to push all the mail generated, you need to edit the /etc/mail/ and in the :
block. you have to replace it with your SMTP server address. your SMTP server needs to be accepting email from your linux box.
Hope this helps.
