If it finds a message directed to two lists, it selects one and eliminates the other. Thus, for example, mail to "jordan" and "current" and "hackers" would go only to "current", deleting the duplication. The rule base would have to be a little more complicated. Mail to x, cc to y might be a little harder to justify sending only to y when both x and y are lists. Alternately, might it be possible, but more complicated, to do something similar by detecting duplicate messages. You can apply a cannonical filter to recognize that a message will be received by a higher priority list. The highest priority list would send one copy to everyone on any of the lists referenced.
