Precisely his point, I am sure!

As a practical matter, due to the nature of the mask (i.e. only the first /N
bits matter), I'm not sure it makes any difference whether one uses
194.90.15.0/24 (correct) or 194.90.15.1/24 (incorrect). But, technically,
Tony's observation is accurate. A poorly written piece of code could possibly
screw up any netmask comparisons using an incorrectly specified CIDR such as
the above example. But I would never imagine Exim to have anything that badly
written in it! :)
