I must agree.  The only content criteria we have for SURBLs is
inclusion in spam and exclusion in ham.  Aside from the phishing
list (which also happens to be very spammy), all the SURBL lists
contain spam domains.  Spam versus ham should remain our only
criteria for inclusion or now.

Thanks for the information about the mailpolice list.  Perhaps
that will be useful to some folks.
