[Exim] limiting mails per user

hi,

i am looking for a solution to do the following within exim:

accounting the mails a user sends via localtransport and limit the number of
these mails within a time intervall.

Is this possible with normal exim-config or do i need to code with the
integrated perl?

thanx

andreas
