Activity

• Open Thunderbird.
• I send you a spam message, but Thunderbird still doesn't know, so mark it as junk mail.
• I send you a similar spam message, and Thunderbird marks it as such.
• I send you a legitimate message, but Thunderbird thinks it is spam, so tell him it is not.
• Now I send you another legitimate message, which Thundie accepts.
• If I send you a spam message, it handles it as junk.
