What Mailman version is this? The default in the distribution is 500
and should only be changed in mm_cfg.py.

One recipient per email (smtp) transaction with the MTA (in other
words, one file per recipient), but instead of setting SMTP_MAX_RCPTS
= 1, set VERP_DELIVERY_INTERVAL = 1 which will cause every post to be
sent individually with a VERP like envelope sender for improved bounce
processing and message tracking.
