Mail loops are not the problem. The problem is that mailers sometimes get crazy and send 200 copies of the same message to the list. And there are time window problems that make it possible for a message to be delivered twice if the line fails just at the wrong time, too. You can disable this code, but don't complain if some day the 500 people on your list each get 200 copies of the same message. >2.

By default, this is 50. But the best solution seems to be adding a time stamp to the FAQ file automatically. This will be useful to subscribers in countries where everything has to go through a 9.6k link because there is no money for more bandwidth, as larger messages (such as FAQ's) tend to be queued after small ones.
