Yes, the are. But the philosophy is the same.

Nope. Good book. Gives a nice Exim introduction. Exim spec that is
downloadable from the ftp site is a reference document. For newcomers it
may be somewhat hard to swallow. When I was learing Exim, there was no
Exim book, so I just printed out the reference and started reading it.
That worked nice.

No. Exim 3 developement is dead.

The fundamentals are mostly the same.

Yes. Exim 4 offers you a lot better control with fewer options.

Go ahead, read the book. But test the stuff you learn on Exim 4. Look at
the default config file for Exim 4 - it's well commented and is a good
starting point for a newbie.
Good luck.
