I often have large volumes of incoming mail being processed through large numbers of message filters, and it is somewhat annoying to have the same error box come up multiple times telling me that a message couldn't be filtered to the same folder due to a problem. I would like to suggest that when a message filter fails in this way the filter should be set to a new "Suspended" state, and that some easy mechanism is provided to say "Reset all suspended filters to active and re-run them". For example today, having not used my email for a couple of days, I had one particular filter generate this same error more than ten times (and multiple other filters several times each).
