Mailfront is a an SMTP daemon widely used with qmail, replacing the old 1998 daemon which is a little underpowered for today's mail.
Find it here: http://www.untroubled.org/mailfront/ It needs the bglibs and cvm libraries available at the same place. There are packages and RPMs for them in the usual places. Mailfront has a nice plugin design, so I've written a pair of plugins. One is called authres, which checks SPF, DKIM, and DMARC, adds an Authentication-Results header to the message, and can optionally reject messages that fail with p=reject. You can have an exception file to deal with domains who publish DMARC policies that don't match their actual sending policies. If you want to do quarantine, you can do that by looking at the A-R header when you deliver mail. The other plugin is arlog, same thing but also logs the results in a mysql database.

If you find bugs, feel free to fix them and send patches.
