How can a limit be set on a single account or all accounts in a

This may have been covered already but I am behind a little on this.

You can only really limit it on a server level with concurrencyremote.
What are you trying to accomplish?
This spawned from a another list I was working on talking about security
on large networks.
I did have 2 accounts get compromised for weak passwords. I had over
50,000 emails go out in 2 days and blacklisting me in few places.
I can usually resolve this quickly but I need a watchdog to either
alter me or limit my server from sending so much mail out at one time.
Which can raise red flags all over the place with RBLs and other block
lists.

That's indeed an interesting problem. I really like the way that
gmane.org handles it.
gmane.org handles the list submission side of things (as opposed to the
reading/delivery side) by throttling the frequency of sending, per user.
It will only send out one message per user every 5 minutes. If there are
more messages than that, they remain in the queue. It accomplishes this
by processing the send queue every 5 minutes, and processing only one
message per sender.
Perhaps qmail-send could (be modified to) do something similar for
remote deliveries (I don't see a point in doing this for messages going
to qmail-local). Any developers out there who would like to look into this?
