Why does KBiff always think my POP3 mail is new?
POP3 is a very difficult protocol to accurately determine what mail is “new” and what isn’t. There is a decently odd heuristic in KBiff that works for the vast majority of cases. If it doesn’t work for you, then while you are not alone, you are in the minority. I won’t change the POP3 code when it works for most people.
