Your filters do not work because the msgFilterRules.dat file, which contains your filters, could not be read. A new msgFilterRules.dat file will be created and a backup of the old file, called rulesbackup.dat, will be created in the same directory.
您的过滤器因为无法读取包含您过滤器的 msgFilterRules.dat 文件而无法工作。将创建名称为 msgFilterRules.dat 的新文件，名称为 rulesbackup.dat 的旧文件的备份也将保存在同一个目录中。
