Darrell has created a new configuration database called rav that containes two fields for managing the whitelist/blacklist. These fields are: wbl_accept and wbl_reject.
I use RAV and actively update my WBL and have never experienced a single problem with it. What kind of information are you trying to input?
Interesting that you are having to add alot of blacklist entries. I find that RAV lets only the odd spam message through without tagging it. If anything, it gets a little too aggressive with its tagging. 90%+ of the WBL entries I have are whitelist entries. What is your anti-spam configuration? Is is possible that you have the anit-spam funtion disabled?
