Hello everyone.

I have a question regarding open relays. I know what they are and why they
are very important.
But what I wanted to know is, what measures can I take on my end to ensure
that my postfix Mail Gateway is not an open relay?

I've reading over the documentation on the postfix.org web site right now,
but I was hoping to get some insight on some extra added layers of security
I could use to ensure that my server is configured correctly and is not an
open relay.

I really like postfix. A big reason why I chose it was due to its track
record as well as how much more secure it was over other MTA's.

So if anyone has some suggestions on how I can further enhance my Mail
Gateway security, I would very much appreciate it.

Thanks.

Jason
