Perhaps you need have/check a reverse dns entry on the domain from which the emails exit your network. How does the headers look like? Does delivering to gmail work?

Some are suggesting setting up DKIM. If available I'd recommend (instead of trying to hack your config to fool headers) is to see if you can use a relay to send emails from that server instead, a designated mail server somewhere on your network such as Exchange. In that case (and it looks like you're using postfix) in /etc/postfix/main.cf add a line relayhost = 10.x.x.x the IP being said relay server IP
