With mail newer than $minimal_backoff_time it behaves like 20140109.
The changes of 20140209 only happen with older mail. I tried many
different solutions over several days before settling on this one.

I guess one could do that, but it does not scale well because it
requires a babysitter.
Like the other thread, this requires a better way to handle persistent
(TLS or other) soft errors.
