Email notifcation when PM limit reached

[shershen08]

Does anyone know any mod or plugin/product that can enable email notifcation to users when their PM limit is close to the end?

This is actually a default feature.

I thought it is but tryed to reproduce it and didn't get any result

i've made user group with 10 PMs limit and put there one test-user
his limit is now overflown and his can see a text notification about it in PM interface, but no letter has been received.

it's done on some cron run as i think - how it's called?
