we have a exim mail server, where we implemented an ACL to limit shipments
of users and thus avoid SPAM
a text file where are defined the limit of
each user, whether they can help or know another method, my idea is that I
want setear for example a user can only send 10 messages per day and another
allowing unlimited
Using mysql here, but you can also adapt the method to a plain text file:
acl_check_rcpt:
deny authenticated = *
ratelimit = ${lookup mysql{Q_RATELIMIT}} / 1h / strict /
$authenticated_id
log_message = Authenticated sender rate $authenticated_id
$authenticated_sender $sender_rate / $sender_rate_period
where Q_RATELIMIT is the query: select ratelimit from table where
username=...
Unlimited users' passwords also can be stolen and used for spamming.
