From: Ole Wolf <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Setting TMDA to let spamassassin low-scores through Date: Tue, 23 Sep 2003 11:21:22 +0200
I recall that Kyle Hasselbacher (right?) recently said something about letting email with a spamassassin score of 3 or lower through TMDA unhindered, and send a confirmation email to anything higher (unless whitelisted or confirmed, of course).
How did you do that?
That was me actually. It's pretty simple really, just two lines in your incoming filter:
headers '^X-Spam-Status:\sNo' ok headers '^X-Spam-Status:\sYes' confirm
Then set your spamassassin threshold to 3.0 and you're all set.
Note: This could cause collateral damage to spoofed addresses, however their own spam system should detect and handle this fairly easily. I recommend using some conservative RBLs at the MTA level to keep that sort of activity to a minimum. I chose sbl.spamhaus.org which maintains a list of the worst confirmed spammers, relays.ordb.org which tracks servers which are open relays (though once common, open relaying is no longer recommended due to abuse), and proxies.relays.monkeys.com which tracks servers with misconfigured proxies that allow relaying.
