I work on this principle, which is one widely used by anyone writing
software that takes input and produces output: "Be very strict about what
you write, and very flexible about what you read".

If everyone who implemented RFC's only accepted input that strictly adhered
to the letter of all other RFC's, the net simply wouldn't work. Not even
TCP would work (cf. differences between the DEC and the BSD TCP/IP stack).

You haven't seen what you can do to the MailScanner.conf file and still
leave it perfectly parseable!
