Hello, SpamAssassin tags mail with headers X-Spam-.... But, what if there were some headers like these, as with mail that already passed someones SpamAssassin and has X-Spam-Score, before being recieved by my server?
Will it remove them, replace them or simply add new ones? In the latter case, how do I tell headers, added by my SpamAssassin, from headers, that were there before my mail server?
