# Advertising Letter Filtering mechanism
# in principle, the probability of miscalculation is higher, because some electronic periodicals are sent using the relevant programs, so special letters will be transferred to a specific file for future manual confirmation. After the confirmation is correct, then change the setting to/dev/null, so that the letter can be deleted directly, so as to avoid the waste of hard disk space.
