The language is string expansion, with some operators and conditional. > I recommend the current documentation instead of the 2007 book.

The two should supplement each other. The book is a tutorial and guide, the online docs are a reference. > For the adventurous and wealthy, your best bet is a trip to the USA and > a week long stay with Phil - afterwards you will know an awful lot about > Exim :-) For clarity: there are two Phil's involved with Exim. Phil Hazel wrote it, has now retired from his job at the University of Cambridge, keeps an eye on things from a distance but mostly enjoys his well-earned retirement. He knows all of Exim exceedingly well. As far as I know, he's still in Blighty. I'm Phil Pennock, I'm one of the maintainers; I'm British, but living in the USA. I have a full-time job where in 2012Q1 we'll be migrating things to Exim, and where my employer (Twitter) is generous enough to let me spend focused work time on Exim when there's a major security-driven release; but I do not have a lot of spare time. Life at a start-up. So a week with me would involve playing with cats and talking to my wife and my occasionally blinking and remembering there's someone visiting. It would not be a productive use of your time. Unless you really like playing with cats. I am not an authority on every corner of Exim; I forget details, or occasionally learn something new. I am capable of using the "less" text-viewer on the "spec.txt" which ships with Exim and finding my way around things quickly. I recommend the Exim4 book (not the Exim3 book) for an introduction and guide, and looking at: http://www.exim.org/exim-html-current/doc/html/spec_html/index.html which is a prettier form of "spec.txt" and pay very close attention to chapter 3.
