Actually rate-limiting a outbound flow is quite difficult. There are some possible approaches discussed on one of the wiki pages, I think. However, for your case, it would be far simpler to ratelimit the inbound flow, per-sender. There's an ACL condition to to that (with appropriate choice of parameters). -- Cheers, Jeremy -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
