I'll fill in for Douglas on this one... Simply, we bounce (some but not all) mail because the number of concurrent connections sometimes stays high for a long period of time - days at a time - and forkserver never attaches a process to some connections, resulting in them never seeing a banner and timing out. If each SMTP connection has only a 50% chance of getting a connection open, you run out of retries on the other side on a non-trivial number of messages. Furthermore, with gmail in particular, we run into issues where we wind up eating too many of their resources, because each time they retry and fail, they have a socket open for >5 minutes (until the things times out).
