The document available at http://www.postfix.org/QSHAPE_README.html#backlog shows how to define a dedicated transport for one specific destination, how to play around with concurrency and the number of smtp delivery agents available, makes remarks about the use of static connection caching and so on. You cannot copy/paste the example given there, but it should show you how you can approach this problem. > What's also baking my noodle, is whether the remote party might have > an issue with connections hanging around..

Postfix supports the smtp_data_done_timeout, though this might not exactly be what you are lokking for: Postfix will try to deliver "at least once", not "exactly one". If you do not receive a server response on a hanging connection and smtp_data_done_timeout kicks in, the mail might be delivered multiple times.
