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?
This is one feature I planned already to put inside chkuser, limiting
acceptance (for authenticated users) to both a user limit and a domain
limit.
I feel two basic limits should be placed both for domain and single
user: daily threshold and montly threshold. limits like 500 daily and
10000 montly for user are very large for single user and useless for
spammers.
But, honestly, I've no time to implement it in short period.

Tonino
