Processing Premature Bounces

It looks like this issue, discussed at http://forum.civicrm.org/index.php/topic,5245.0.html may not go away soon and it looks like other CiviCRM installations may have the same issue.

Basically, some emails are bounced without even being sent.  When this happens, usually, but maybe not always, an email has a "Connection Refused" error and then that email and every other remaining email in the batch gets bounced.  Previous and later batches are fine, unless a similar error occurs.  This has been happening for us for the last 6 months, although we didn't realize it at first.  We have a procedure to resend the bounces discussed in the link above, but there might be a better way.

Since we are controlling the sending, there must be a routine that loops through each email in the batch and sends out the email.  When a problem happens, then all later emails in the batch are also bounced.  Can someone tell me where this routine is?   Perhaps the routine could be modified so that when a connection refused message happens, that the routine tries again before giving up on that email and the rest of the batch.  Perhaps since the error does not happen very often, if we tried 2 or 3 times before giving up, all the emails would go out and eliminate us having to process emails 2 or 3 times to get all the emails out. 

What do you think?  Possibility?
