mynetworks = 192.168.0.0/24, 127.0.0.0/8
this will allow only computers with ip address of 192.168.x.x (most likely your office computers use this ip) to send email.

Hello, everyone!
They say Postfix is NOT an open relay out-of-the-box. I believer them because it won't work for you out-of-the-box. But when I configured it to use my own hostname, domain, and network address, it was declared an open relay by 2 blacklists after a few hours because it kept relaying mails to thousands of "<some domains>.ru" addresses!
What is the quickest way to "close" its "openness?"
I've already tried the various "smtpd_client_restrictions, ...sender_restrictions, ek-ek, to no avail. "
I've gone around the world thru cyberspace, but all the solutions I've seen, including pop-before-smtp, haven't closed all the holes!
