Postfix runs fine on FreeBSD 8 (here, since November 2009) as well as any FreeBSD vesion that I have been running since I started work on Postfix in 1997.
Your problem is a broken operating system that causes timeouts in
Amavis, Postfix, and in other programs.
This is the Postfix mailing list. It is not the right place to debug
broken operating system installations.
Once you have a properly working operating system, you are welcome
to ask any Postfix related question here.
