I have several mail folders (linux mailbox files) that are a good source of whitelist information. For example, I am sure that all To: addresses in my sent folder, and all From: addresses in my friends or ebay folder, are good.
So what I would like to do is to generate a file with a list of addresses that I know are good, and to give them a good negative score (to decrease probability of false positive). Based on my readings, I could not find a feature that would offer this, have I missed anything? i
