It is not clear that the delay you are reporting is the result of the
DKIM milter. How big is your incoming queue? Is your system CPU, disk
or network starved?
The queue manager serially imports mail from the incoming queue. Messages
are elgible for import as soon as cleanup processing is complete. What we
don't know here is when cleanup (including milter) processing completed.
We also don't know whether trivial-rewrite is using any high-latency
lookup tables, whether the queue manager is not getting enough CPU or
disk I/O, whether the active queue is full, ...
You need to identify the cause of the delay first.
