This may be short sighted, though. If you run a permanently connected
system on the net you got to understand what is happening. And it is
not that difficult to master. Computer literacy is all that is
In any case I did not want to go into too much detail.

Actually, you are not correct. The most recent is 8.9. This is beta
and I haven't moved from 8.8.9 yet, because of two significant changes,
that affect my setup.

This is quite true.

Again, I have to differ. At least in some respect.
Sendmail has a very large and very cryptic configuration file, mine is
1189 lines long. This is what kept most people off sendmail and made
me use smail, because one can actually understand smail's
configuration files :-)-O
However, it now uses a macro package available on linux and many other
unixes which reduces the size in my case to 29. RedHat indeed comes
very well preconfigured (12 lines).
Run through the macro processor it produces the long and ugly file.

Well, one rather does need the bible, in particular if you want to
figure out how to configure sendmail for a UUCP dialup solution. Took
a weekend and a week later I found a mini-HOWTO on a linux CD :-)-O
The new SPAM features are not described in the book. Interestingly I
could not got some of it working in my particular setup so I sent a
mail to the author in Germany on a Sunday afternoon. Got his reply
after 9 minutes and had it working after 15.
