E-mail Message Size Limit Per Packet

As a System Administrator, I would like to be able to limit the size of attachments or sent emails on an individual account basis in order to balance server loads.

============

I would suggest including some method to limit the size of attachments or emails sent.

I know inside (Exim Configuration Manager> Advanced Editor)

we can adjust the message_size_limit, but this setting works globally.

It would be very important and useful to be able to set up individual accounts.

Maybe per pack.
