an announcement was just made elsewhere that the free RBL services
from MAPS are going away on July 31st. evidently, because the bulk of
the services were free, very few picked up the pay service called
RBL+, and it would seem that MAPS needs to work on the bottom line to
stay in business.
i have no idea what the fee schedules are likely to be; hopefully MAPS
will publish something on their web site in the near future.
what this means to exim users is that you'll probably need to remove
the MAPS services from your exim configs come the end of the month
unless you (or your management) decide to pay a MAPS subscription fee.
