By the way: you can add IP checking as well, by adding the LHS of
http://basic.wirehub.nl/blockedIPs.txt and a RHS of REJECT (or an error
message of your choice) to your access.db. That is how it used to work over
here before we moved IP blocking to a DNSBL.

Something like
fetch -m http://basic.wirehub.nl/blockedIPs.txt
awk '{print $1" REJECT"}' < blockedIPs.txt >> access (*)
and hashing it to an access.db is all you need, really.

(*) of course, '>' or '>>' depends on the order in which you create the
access file, and where you start adding stuff to it)

The file is not yet available through rsync, but making it available is not
too hard, of course.
