To help prevent mailer loops from bogging down the network, has any thought ever been given to installing 'circuit breaker' parameters to lists? I envision keeping a counter of the number of mail items processed on given list on a given day. If the number exceeds a programable threshold, the 'breaker trips', further traffic to the list is disabled, and a message is sent off to the list owner, who can hopefully figure out and correct the problem. This would be even more valuable for those lists which distribute once a day during the wee hours of the morning, when normal network watchdogs are either asleep, or reaching the end of their waking hours. For example: Risks digest comes out a couple times a week. Seeing 2 in a day is uncommon, and 10 would be almost unheard of. A short time back a loop developed and I got about 60 copies of a reject message. If the circuit breaker had been set at 10, there would have been a lot less network traffic.
