Is available smtp-limiter plugin or something similar for ISPConfig? It would be nicely to know when some software would send some notifications on email about exceeded limit of sending emails for particular user account/domain.
not part of ispconfig, but you can use postfwd or policyd (aka "cluebringer") to do the limiting - I've never tried to send notifications, but I'd imagine there would be ways to do that
It would be nice if devs would provide something similar. Feature request. PS http://postfwd.org/ratelimits.html https://wiki.policyd.org/quotas Now time to find something with notifications.
