Actually, it suffices to use:
myhostname = mail.mydomain.tld
relayhost = [smtp.myisp.net]
since mynetworks is usually correctly derived from the network config, and mydomain is being derived from myhostname.
I have yet to see money from the book....
The point is, no matter how careful you and the editor are, there's always errors in a book - fortunately most of them were odd typos in our case - except for the showstopper "maildrop" bug...
With the Blum book it was different: I stopped after the first 80 pages, sent the sheer amount of bugs to the publisher. Never SAW errata for that book after that.
Even Wietse complained and said the SMTP section has to be enhanced when we met him. So, don't keep your fingers crossed - it will get bigger still in the German edition.
What for? It's "The book of Postfix" and not the "Book of I shall convert thee to Postfix". No point in converting people who like to patch their MTAs to make them usable for today's internet.

So we should have kept the errors secret instead? We're at least honest and report the errors. Have you reported an error yet?
The Blum book was outdated when it came out. I personally found it extremely superficial and also imprecise.

The point is that YOU don't usually need them. But when you do: Postfix: Set them differently qmail: It's Patch time again.
