   which does not assist with the problem faced by the OP who was trying to
avoid blocking legitimate incoming emails, whatever the originating address.
   A similar problem can exist if someone has to use a facility provided by
their hotel. It may be a temporary location that is infected with some
unknown worm or virus. Another example would be an exhibition centre such as
Olympia, where there is a resident block allocation for use of the stand
holders, but that block of addresses is well known and subject to continuous
attack. Anything sourced from there could trigger a spamblock, which could
again make a normal blacklist give a false positive.
