First off I should preface this by saying that I was a high school student in Utah last year, and I have inside information on this whole situation. They know there are problems with the filtering system. They know SmartFilter sucks, they want to fix it and this last summer they planned on moving to a better system such as Bess which allows much more control over filtering and has a better site list. However Michael Simms created the whole controversy and as such for political reasons the tech guys were forbidden from changing the software. Had they been able to do so, the problems would have been fixed. Bess allows powerful filtering you can specific things like block sex but not sex and art or not sex and education etc, and generally their system is better. Had censorware minded there own business instead of trying to get kids hooked on porn the problems would have been at least reduced. Furthermore I know I don't want my kids going to some teacher's class who that morning looked up his latest kiddie porn on the net. I've seen the logs, believe me there are teachers out there doing this, unfortunately UEN is too scared to do anything about this. Not only that but kids are looking at porn, I caught them in the school library doing such when I went there. Without blocking it would happen a lot more, I don't care what anyone says but pornography is addictive. Until you turn 18, you shouldn't be able to access it, because it will mess you up, just look at Ted Bundy who attributed some of his problems to porn. I'm sorry, but I applaud UEN for what they are doing, and just wish people would leave them alone and allow them to fix the system. Sure it has problems, but they can be fixed, if they're not busy dealing with annoying requests from people. Additionally on the sites that were blocked, many of them at one time or another had inappropriate material and the server is being a bit cautious.
I've been using qmail for a couple years and it works great. It does feature SPAM filtering and prevention techniques, though some of them aren't distributed with the man package. However from being on the qmail mailing list for a while I can tell you SPAM prevention was a big focus.
Additionally when paired with serialmail qmail runs really well over modem links. You can setup a virtualdomain to hold mail in a queue until a user connects and then flush the mail to the users personal linux box for delivery into user's mailboxes. I realize this can be done with other tools, but qmail does this easily and it works great.
Also regarding a POP server, personally I use a patched version of the University of Washington's POP/IMAP server and it runs really well. I know a large ISP who does this as well.
Finally you may be interested to know that there are some very large sites on the net using qmail, or at least they appear to be (you never know for sure). I believe Rocketmail (or maybe it was hotmail), and Internic were both believed to be using qmail.
Overall I highly recommend using qmail, it runs great and is easier to configure than sendmail.
