I had a problem with an IP address sneaking into Postscreen's whitelist. I added the IP address to postscreen_access.cidr and set it to REJECT, as I typically do with problem IP ranges. It seemed as though the temporary whitelist was overriding my request to reject the mail though. I ended up removing postscreen_cache.db and restarting Postfix. Is there a way to go into that database and manually remove specific entries? Most of them are fine, which is why I was sad to have to do the brute force technique that I used.
I’m guessing it’s not possible but figured I’d ask.
