Subject: [PATCH] Raise smtp_accept_max for openstack_project::lists

Increase Exim's smtp_accept_max on the listserv from its default 20
to allow handling more concurrent inbound delivery connections, but
also set a reasonably low per-host max to avoid any one sender
performing a denial of service.
