Generically speaking -- and I'm digesting several decades of experience into a few paragraphs, so I'm going to make some sweeping statements that, of course, have exceptions. Except for the last one. If you've never done this before, then stick with sendmail because it minimizes the probability that you'll screw up. Postfix is easier to configure than sendmail. It also benefits from having been designed after many years of experience with sendmail, so it incorporates some lessons learned. It is relatively straighforward to switch between the two, once you've mastered some basic concepts. In the contemporary environment, either is a good choice for relatively secure, relatively high-performance environments. Both can be configured/customized extensively and there is plenty of support for both, from multiple sources. Exim is newer and arguably still easier to configure. It might be a good choice for someone with limited requirements and little experience. Courier is well-integrated with the other components necessary to make a fully-featured mail server, and is worth consideration if its feature set overlaps well with your requirements. Qmail is crap and is only used by people who don't know any better. ---Rsk
