I haven't bothered to get this redone yet, but here's a little something:
My FreeBSD Virtual Mail How-To using postfix+cyrus+sasl2+mysql+postfixadmin
which I moved to a Wiki on 9/11/2005 in order to make it easier to update and use, etc.
Some of my other projects, such as the SquirrelMail SPF plug-in, can be found on my
the wistful.net wiki
