[Mailman3-dev] Feature request: saturation MTA injection

[J C Lawrence]

A lot of MLM MTA tuning comes down to handling the spool most
efficiently, and that is often more easily handled/optimised in the
cases where the spool is fat/large rather than when it is nearly empty.
VERP exacerbates this problem.  

Request:

  The queue runner, when handling MTA injection, forks up to N
  instances/threads, where N <= RCPT TO blocks and N <= a value
  configured in mm_cfg.py.  

The goal is most rapid injection of the list broadcast into the spool.
This is particularly valuable for large moderated lists.
