The RFC-manadated *number codes* are hard-wired into Exim (well - as 'hard' as
any open-source project - they, too can be altered and recomplied).
However - the *text string* associated with each response code has a default -
pretty much what most smtp-engine implementors use...
... and also a provision for customization by simply setting a variable.
Said variable string can be set at more than one place on more than one
conditional, ergo it is the entity configuring the server in question who has
the answer - not the Exim coders.
