Did you check all major blacklists? Do you have a dynamic IP address? Do you have proper SPF and PTR records for your domains?

Same problem as before. Please check if you're blacklisted. Does your server have a dynamic IP address and/or is it on a DSL line or something like that?
I had the same problem when I first started using ISPConfig. It was because my ip was dynamic and that I had to use a relayhost. This is done by editing /etc/postfix/main.cf. Locate the line that says relayhost and add your smtp server info to it. e.g. relayhost = isp.smtp.com Of course you'll have to put in the smtp server that was provided to you by your ISP.
If you want to use a relayhost, have a look here: http://www.howtoforge.com/forums/showthread.php?t=72&highlight=relayhost
