How to specify maximum # of outgoing emails from SMTP by domain

sendmailsmtp

i have sendmail, and i am sending mailshot every week.
how can i tell my sendmail to limit the number of outgoing emails to a specific domain per hour (to avoid getting blocked by mail servers)
for example:
to send 500 email/hour at most to @yahoo.com
and the same for @gmail.com and so on

Thanks for your help

The best way to solve the problem is to use something like milter-limit which is desgined specifically to throttle messages and can do this on a per-domain limit

Rate limit exim per user basis

Expanding on HBruijn's answer, I recommend this ACL segment:

# Keep authenticated users under control
deny authenticated = *
     set acl_c_msg_limit=${lookup{$sender_address}nwildlsearch{/etc/exim/send_limits}}
     ratelimit = $acl_c_msg_limit / 1d / strict / $authenticated_id

Then you create the /etc/exim/send_limits file and have this in there:

# Commented lines and blank lines are ignored
# Format is     EMAIL: LIMIT
user1@domain1.com: 100
user2@domain1.com: 200
user3@domainXX.com: 100

# Must be the last line, this is the default limit
*@*: 50

This is untested, but it should get you headed in the right direction.
