* This is the vopmailbeta mailing list *
If you're using emailanal (the executable that compiles stats about VOPMail's usage) over a period of time you can get a pretty good idea of which RBLs are doing you the most good. I believe that the order in which you list your RBLs can taint the information, but a least it's a good source of additional information. A suggested order for your RBL list has been posted here before.
