I have a similar problem. We forward all our mail to a smart host who
does AV scanning and spam filtering. Problem is they only accept 40
concurrent connections and then refuse anymore. If we do any massive
mails then we normal hit the 40 concurrent connections limit which then
causes ALL outbound mail to get instantly deferred!
