I added a new mailman list with 4 subscribers. One of the subscribers
was the same earthlink address as the 600+ subscriber email list.
When a messages was sent to both lists - the earthlink subscriber ONLY
received the message from the 4 subscriber list.
Seems Mailman is cablable of getting the message out at least on a small
list. Any idea what the threshold is?
Any other tests that can be done to futher isolate this pesky issue?
