I >believe this is the problem. David, Ron, Those list msgs SHOULD as leave as a "thundering herd" at LAN speeds, with no DNS lookups. To prevent the herd from overwhelming any one destination MTA, there must be herd factor of x msgs/herd. The herd factor needs to be settable, and to have a queue run time separate from the general Imail SMTP retry (unreachable) timeout. In Ron's case (I don't know what his SMTP retry timeout, assume a reasonable 20 min) (500 msgs) / (5 per herd) = 100 100 herds x 20 minutes/retry = 2000 mins = 33 hours to send out just one list msg to all 500 list members, in theory.
