You mention that Postfix has a shorter list of security vulnerabilities than Sendmail. In the recent times, Sendmail has performed very well. Also keep in mind that Sendmail is over 23 years old -- it's had a lot more time to be tested for these things. If you mentioned that Postfix scales better than Sendmail, I'd have marked that as credable; however, Sendmail's M4 configuration is so easy that even a monkey could do it.
As a software package, Sendmail works great. It is easy to configure. It has proven itself secure in the recent years. Don't knock it for the wrong things.
May be you'd check more. Postfix is designed basically to be a secure alternative to Sendmail, check its site. And it does have a better record.
I'd say the worst thing about sendmail is the configuration, by the way. Probably you are a M4 veteran, so you don't know how complicated it is. Frankly, that was the reason I switched from sendmail to postfix, circa redhat 7.3, before it became their default. And I am not really a newbie..
thanks for the walk through only had Ubuntu installed (or any type of Linux) for a couple of days and I'm already runing my own server...pure magic
would this be a better starting point?
would it change everything in this howto?

The ubuntu server distribution did not exist at the time I've written this howto. I'am pretty sure that the howto will work fine with Ubuntu Server distribution too, but I've not tested it yet.
