There shouldn't be, but it is possible to misconfigure things between
Mailman and the MTA such that things don't work well when lists have
too many members.

So maybe this is an issue for Apple?

What do you see in various logs such as the MTA's logs and Mailman's
smtp and smtp-failure logs?
My first guess is that the MTA is actually accepting some or all
recipients of the message but is returning some status to Mailman
indicating a retryable failure. If you have invalid local addresses on
the list, this could be related to <http://bugs.python.org/issue5713>.
In any case, I suggest setting
SMTP_MAX_RCPTS = 10
in mm_cfg.py and restarting Mailman. That may help
On the other hand, if by "kill the mail system" you mean Postfix and
not Mailman, then this may not be a Mailman issue at all.
