When a precondition fails, the router is not run at all. Exim skips to
the next router. This is not "fail".

When a router does run (all the preconditions succeed), one of the
possible results is "decline", which means "I might have been able to
handle this address, but when I went and looked things up, I found that
I could not", e.g. a dnslookup router looks in the DNS and finds
nothing.
If a router returns "fail" it means "I recognize this address, and it
should be bounced" e.g. a redirect router finding a :fail: item in an
alias file.
Does that help?
