Mark as junk in Evolution, train SpamAssassin on server

Evolution has a feature for marking e-mail as junk. This will set an IMAP keyword “Junk” on those messages. On my mail server I run Dovecot as IMAP server and Spamassassin through Amavis to filter spam. How could I get Spamassassin to learn that all e-mails marked as junk in Evolution are spam? With a shell script, of course. I currently run it as root but maybe it is possible to give the amavis user permissions to read my Maildir…

#!/bin/sh

if [ `whoami` != 'root' ]; then
  exec sudo $0 [email protected]
fi

find ~david/Maildir -name dovecot-keywords | (
while read keywords; do

  DIR=`dirname $keywords`
  #echo $DIR >&2
  # XXX only supports 10 keywords
  CHAR=`awk '$2 == "Junk" { print $1; quit;  }' $keywords |
    tr '0-9' 'a-j'`

  if [ "$CHAR" ]; then
    find $DIR/cur $DIR/new -regex "[^,]*,[^,]*$CHAR.*" |
      xargs sa-learn --dbpath /var/lib/amavis/.spamassassin/ --spam
  fi

done
)
/etc/init.d/spamassassin reload

Policy notification from Google

My Swedish site Folkmun allows anyone to add words and their definitions. It’s a simple Swedish version of Urban Dictionary. Some people add very explicit words and I had totally forgotten that such words may clash with Google AdSense policies. Today I received a friendly warning:

While reviewing your account, we noticed that you are currently displaying Google ads in a manner that is not compliant with our policies. For instance, we found violations of AdSense policies on pages such as
http://www.folkmun.se/definition/Apaj%C3%A4vel. Please note that this URL is an example and that the same violations may exist on other pages of your website.

Needless to say, I have made a couple of modifications to the site, including hiding ads when displaying explicit words or definitions. If this wasn’t good enough, I’ll know in a couple of days…

New site: Blekinge.IT

As much as I try to get rid of domains I don’t use, I can’t avoid registering new domains. I recently registered two domains (singular and plural) for a project with codename Green November.

Another domain I recently registered is Blekinge.IT. At some point in the future I want it to be a site about IT and telecommunications in the Swedish province Blekinge, but for now I only use it to aggregate local news sources.

This was also a test in registering .it domains. I had to print, sign and send a fax (!) to fulfill the registration, but otherwise it was really easy.

PulseAudio support in Wine makes Spotify work better!

For various reasons (see bottom of WinePulse – PulseAudio for Wine) the main branch of Wine does not support PulseAudio. This makes Spotify under Wine misbehave a bit, but fortunately there is a solution! A person called Neil Wilson has been kind enough to provide PPA packages of Wine with the WinePulse patch. I’m installning this PPA on all my Ubuntu machines where me of my wife use Spotify.
