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.
Filterlaringiz ishlamadi, chunki filterlaringiz saqlangan msgFilterRules.dat faylini o‘qib bo‘lmadi. Yangi msgFilterRules.dat fayli yaratiladi va eski faylning rulesbackup.dat deb nomlangan zaxira nusxasi ayni shu jillda yaratiladi.
