Failures showing in the log file?
OK, something I notice in my posts log is a message not entirely unlike the following:
Jul 15 09:27:31 2007 (32571) post to list from user@wherever.com, size=5706, message-id=<redacted>, 557 failures
Now, as time progresses, that "failures" number counts down, and ultimately, there is a "success" asociated with that number. sWhat, precisely, does this message mean?

Look in the smtp-failure log for a more informative message including a reason.
What is happening is the outgoing SMTP server (MTA) is accepting only a fraction of the recipients. The rest are queued for retry. Some more recipients are accepted on the retry, and the rest are queued, and so on.
It may or may not help to set SMTP_MAX_RCPTS to a number smaller that the number that gets accepted each time (in mm_cfg.py), but first get the reason from the smtp-failure log. The best solution depends on the reason. It may be that something in the outgoing MTA needs to be changed.

That would probably mean smtpd_recipient_limit (running Postfix), which I have to set 500. Currently, SMTP_MAX_RCPTS is set to the default of 1000 in Defaults.py. I'm wondering, then: given this, would setting this to, say, 1 cause mailman to deliver one file per email? (This would be an example, of course; doing something like this would most likely bring my server down to its knees.)

What Mailman version is this? The default in the distribution is 500 and should only be changed in mm_cfg.py.

One recipient per email (smtp) transaction with the MTA (in other words, one file per recipient), but instead of setting SMTP_MAX_RCPTS = 1, set VERP_DELIVERY_INTERVAL = 1 which will cause every post to be sent individually with a VERP like envelope sender for improved bounce processing and message tracking.
