And even causing the deaths of the occupants.

If provision of a letter box is a requirement, now that the post office
counters have a plastic size template limiting the size for first class
minimum postage letter to a narrow slot of 165 mmm x 5 mm, perhaps we
can reduce our aperture to that size and still meet the regulation.

What about the "large letter" size? That accomodates C4 envelopes to
take unfolded A4 sheets and up to 25mm thick. A reasonable proportion
of our mail is C4 sized not C5 or DL "letter" sized.

You don't need a letter box, as in hole in a door, but it makes sense
to have a letter box some where that the postie can leave you mail in
so it doesn't blow away, get soaked or stolen. Many places in rural
areas have boxes at the end of their track for post and other
deliveries to be left in.
