FreeBSD and MailScanner

[Pete]

I am going to try and run MaiLScanner on Free BSD on my secondary (very
low volume) mailgateway, i want to run it in a used enviroment as i am
pretty new to BSD but i want to use it in action while i learn as much
as i can.

My question is, is the offical ports tree updated with MS or should just
download the archive posted to this list, extract to
/usr/ports/mail/maillscanner-devel and install from there? maybe
extracting the new devel releases over the top of the previous ones?

I did a /stand/sysinstall and updated the ports tree, but make search
name=mailscanner finds nothing :(

Has anyone wrriten any specific doco for freeBSD/postfix/mailscanner ?
Just follow the guide on BSD and the postfix one on Julian's site?

Thanks in advance
Pete
