Physically, yes. Logically, and this is what matters more: no. Each transport has a separate pool of delivery agent processes transports are scheduled in parallel (well, round-robin, but unless the queue manager is disk-I/O starved, transport allocation is very fast, delay is caused by lack of delivery agents or per-transport, per-nexthop concurrency limits). So the comment about "one queue" is mostly wrong, and the previous post is essentially correct. -- Viktor.
