Currently, SURBL relies on get_uri_list the grab the list of domains,
some uri's may not be appropiate as the basis for which to grab domains
for. If that list could be cut down, then the pool from which the random
selection is made could be more interesting

e.g, I could write a message with maybe 25-30 cid:.* url's and one
real-spamvertised url'. The probability of URIDNSBL.pm to get the
spamvertised url will be higher if the noise from the cid:.* url or
other non-interesting url's could be removed

PS, Does this list need to have the listname prefixed to the subject
line, it wastes a lot of space. I am sure there are other headers one
can filter by
