More info. This is how the queues always look, it's a very typical batch:

The batch is sent out at midnight (not always at midnight, just in this 
case). The active queue is dropping at a pretty good slope - that's 
everyone except Yahoo.

Then there's a green bump at 3am and the active queue is loaded with 
more mails, but this time it's decreasing more slowly. This is when 
basically there's only @yahoo.com email in the queue.

Then it gets thrown in deferred at 4:30am, then briefly in active, then 
deferred again, repeat. It's over 99% @yahoo.com at that point.

This is with minimal_backoff_time = 1000 and maximal_backoff_time = 
2000. I'll try 500 and 1000 instead, maybe that makes the blue bumps 
more narrow.
