Folks:
I've investigated the mail delivery order issue and have come up with some results.
I can confirm that, in some cases, mail is being delivered out of sequence.
Here's the reason ... each message sent from midrange.com is sent to multiple recipients at the same time ... sometimes all those recipients are on the same domain, sometimes not. These messages are sent out on multiple threads running at the same time.
If the server for one recipients on the batch is not responding, the entire batch is delayed. Once the delay cleared (either the mail server responds or my mail server gives up) it goes on to deliver to the rest of the recipients.
Since the mail server is delivering messages on multiple threads, a second message sent AFTER the first, might get delivered before the first because the first message was delayed.
I do have most of the major mail providers (Gmail, yahoo, hotmail, aol, at&t, etc) setup to deliver all in the same batch ... but even that doesn't always get the messages delivered in the correct order. Oddly enough, I've seen situations where message A gets hung up when delivering to Yahoo while message B gets delivered.
There are a few tweaks I'm doing ... so keep an eye on things and let me know PRIVATELY if things get better or stay the same.
