I just took a look at the rbl stuff in the testing version 1.737. IMHO if
rbl_reject_recipients is false (or maybe setting something else to true...) a
header containing the rbl TXT should be added.
If this were done, then individuals could choose not to receive from rbl's
sites using a simple filter rule on the existance of the header, or file it
away for spam detection purposes... Much better than can be done in sendmail
etc...
