Using version 1.7a, with certain mass mailings (some of which I wanted) I started seeing this message in my domino log, and then the router would say that no messages were delivered. And the users would not receive any messages. This only happens on messages with multiple recipients, and even then, it does not happen on every message with multiple recipients. Though the same mass mailing will fail every time.



I fixed this problem on my server by rolling back to version 1.6b.



I rerouted these messages to a server where I could capture all the smtp commands being sent, and the following is a log of a message that was failing
