Exim documentation has a fully detailed section on its built in rate
limiting facility.

Boiling down a quick example:


  warn
    hosts           = *
    ratelimit       = 60 / 1h / strict / per_rcpt /
{$sender_host_address}_sender_rcptlimit
    log_message     = Rate limit in effect ( $sender_host_address )
exceeds $sender_rate in $sender_rate_period


Put that into an ACL where it makes sense (do they restrict number of
deliveries, recipients, commands?)
