>How can I find out why the connection is sometimes being refused?
probably the same situ as when IMGate is trying to deliver to IMail. Imail has a "flood prevention" setting in the SMTP security. "deny hack attempts" IIRC (I hardly ever touch Imail anymore :)) ). When Imail determines it sees a "flood" of deliveries and from one ip, say from you list box or from an IMGate, Imail then dynamically blacklists that ip and refuses subsequent tcp connection attempts.
