It certainly does relate to operation of Exim, and it's specific to Exim
since the recipe won't work in any other MTA.
A recipe is provided for people *other* than David to consider using, and
it's worth warning those people that use of the recipe may lead to
unintended consequences.
Specifically, many DSBLs list machines that are on netblocks not permitted
to operate MTAs. It's quite normal for people on those netblocks to use
Hotmail. It's probably not the intention of most MTA operators to prevent
people from making quite ordinary use of webmail servers.
