[exim] Limit No. of recipients in email client

Hello,

I have couple of requirements.

1- I need to restrict no. of recipients in email client
(outlook/thunderbird). Let say a user can't send email if he has no. of
recipients greater than 100 regardless in To, CC, BCC.
Also. Sender should get an bouce back with customized message.

2- I need to block sender email address temporarily if no. of emails sent
from his email address on specific threshold per hour. And sender email
address should get an customized bounce back message. e.g. No user can send
emails if 50 mails/hour send already from his account.

NOTE: emails should be count as if 10 emails sent in one email. Overall 10
emails should be counted.

I am using Exim 4.

Thank you.
