Hi Anthony, I did that for my mail (not as spam filter, though, but more a header rewrite ... could be procmail), so every such much gtes in the inbox but is flagged very clearly I really like it... but, to be honest, it took me at least 3 months to create my personal whitelist: there are a couple of newsletters (I just saw one from "newsletter" to "newsletter" bcc recipient which would normally deserve an extra spam score for identical from and to) There are mailing lists, mailing list password reminders sent from a different address than normal list mail I even recall one company on ebay that sent from "sales" to "shipping" bcc recipient instead of a normal shipping confirmation
Regards Wolfgang
