[imp] Is there a limit of rules defined in the filter module in theIMP 3.1?

The amount of filters is limited only by the size of the field in MySQL.  Specifically, try changing the pref_value field of the horde_prefs table to mediumtext or longtext instead of the default.  When you fill up the space in the field, a truncated entry is stored.  This truncated entry is not complete, and therefore IMP fails to recognize it.
