we installed an Exim server and found it was easy…: I’m impressed with this mail-server. It works well, is a piece of cake to install and use, and is about the easiest mail-server to customize. It’s also easy to create “rewritting rules” for e-mail addresses that follow a pattern. Also, authenticated smtp is very straight forward as well.

I saw the exim book at books-a-million on sale in the clearance section. It’s probably worth a read because there are some advanced features that I’ve only scratched the surface of. Unlike the sendmail book I have, I doubt I’ll need to wade through chapters just trying to figure out the syntax of the configuration files.

The only unfortunate problem is that most add-on software is designed with sendmail in mind, and anytime you need to interface with a non-sendmail mail-server, there is a good bit of translation needing to be done. If you use debian though, the basic stuff is as easy as apt-get. (BTW, I’m really a red-hat man myself, but that’s just because when I got started, you had to be a guru to get debian set up and now I’m just used to red-hat)
