retry=delay is not entirely sufficient, it would be helpful to also
specify an upper bound (after which the entry will be removed from
the cache and another attempt will not counted as retry, but as a
new one).

Hence my suggestion is to use

retry=min-max

e.g.,

retry=5-3600

where the time unit is minutes (see different reply about
the format of the delay specification).
