There's been an uptick in script kiddies and bots with the Subjam reverse proxy and primary mailservers lately. Not huge, but a couple hundred more on average (IP ban time is currently 48h).

fail2ban is nice to keep them at bay. It's one of many tools a good Linux or BSD network/sysadmin has in their toolbelt.
