I guess this could be done in several ways. There's almost nothing
you can't do in Exim...
This is highly untested, and requires mysql support.
I use something similar to defer mail from hosts who recently
sent virus. :-)
You could also add 'hosts' or 'sender_domains' to the acl statements
to include or exclude hosts/domains from the check.
------
# sql macros for sender_domain limits - limit: num>100 (per 24h)
MYSQL_SENDER_DOMAIN_DEFER = SELECT COUNT(*) as num FROM sender_domain \
WHERE domain='${quote_mysql:$sender_domain}' AND \
DATE_ADD(updated,INTERVAL 1 DAY)>NOW() AND num>100
MYSQL_SENDER_DOMAIN_UPDATE = INSERT INTO sender_domain \
(sender,domain,updated) VALUES \
('${quote_mysql:$sender_address}', \
'${quote_mysql:$sender_domain}',NOW())
MYSQL_SENDER_DOMAIN_DELETE = DELETE FROM sender_domain \
WHERE DATE_ADD(updated,INTERVAL 1 DAY)<NOW()
-------
# possibly in acl_smtp_rcpt, after accepting mail to postmaster/abuse
# query DB for sender_domain limit
defer message = Temporarily deferred due to domain sending limit
condition = ${lookup mysql{MYSQL_SENDER_DOMAIN_DEFER}{Yes}{No}}
# statements to update sender_domain DB (generates empty messages)
warn log_message = ${lookup mysql{MYSQL_SENDER_DOMAIN_UPDATE}{}}
message = ${lookup mysql{MYSQL_SENDER_DOMAIN_DELETE}{}}
-------
Note that this is untested. I just hacked together something from
my current acls...
You must also define a db/table and connect to the db, but I'll
leave that as an exercise
