background

OS X 10.9.2, Server.app 3.0.3

So, Apple wants users to redirect (not forward!) mail to junkmail@ and notjunkmail@ to retrain the spam filter. I think that sucks --- this is not a reasonable way to do things in my opinion.

Anyway, the mechanism seems to be via the launch daemon configured at

/Applications/Server.app/Contents/ServerRoot/System/Library/LaunchDaemons/com.apple.salearn.plist

which, in turn, runs

/Applications/Server.app/Contents/ServerRoot/usr/libexec/spamassassin/sa_learn.pl

and outputs to /Library/Logs/Mail/junkmail.log

config

• Create an account with the username junkmail
• Create an account named notjunkmail too, otherwise the sa_learn.pl script to exit
• Add move-retrain.sh to /usr/local/bin
• Add ca.granitedragon.pre-salearn.plist to /Library/LaunchDaemons
• Then do launchctl load /Library/LaunchDaemons/ca.granitedragon.pre-salearn.plist
• Profit? (Check the log in the morning.)
