One tutorial has been invaluable in setting up my email system. I’m still in the process of testing, but following Christoph Haas’ “ISP-Style Email Service with Debian-Sarge and Postfix” has saved me a lot of time. Not having used linux in any serious way for a couple of years, I’d forgotten how much good documentation there is out there.
