RBL List selection

[Colocation Colocation]

I installed a local caching name-server and that seemed to help my
mail-server quite a bit. I am checking at the spamassasin level, i think its
the most accurate but probably the most intensive.

It seems to be common to add spamhaus at the MTA level as its considered
extremely accurate so unlikely to cause many (if any at all!) false
positives!
