If there's no SMTP server configuration file located at the default 
location — and this default location can vary — SMTP in V5.7 issues no 
diagnostics and commences its default SMTP processing, which includes 
defaulting to open relay.

Operating as an open relay is one of the most truly absurd default 
settings I've ever encountered for a modern SMTP mail server, too.
