Black listing is not a dumb idea, it was one that was founded out of
necessity. Just as there are many ways to ATTEMPT to enforce a speed
limit, there are many ways of combatting spam, RBL is just one of
them, it is however a necessary evil to protect the masses, yes it has
its faults but most everything does.
Identifying servers that are capable of sending spam and thwarting
their access is a viable way to reduce the SPAM. I work for one of
the top 3 ISP's in the country and do understand this technology,
suffice it to say without RBLS working in conjuction with other
technology email would not be an effective means of communication
becuase of the signal to noise ratio.
NET NET: Ed, I am glad you got it fixed...
