Hello,
there is a bug in spamassassin's rule sets that assigns a high spam score to any message sent after 2009. Spamassassin is used by eBox's mail filter so we are hit by this problem.
The issue was fixed in version 3.2.4-1ubutu1.2 , that was released the 1 of January of this year.
To see what version are you using:
# apt-cache policy spamassassinTo update spamassassin:
# apt-get update
# apt-get install spamassassinIf you dont get the good version, maybe you lack the lien for hardy-update in your repository, open '/etc/apt/sources.list' and add the following line if it is missing:
deb http://us.archive.ubuntu.com/ubuntu/ hardy-updates universeThen you should try to run again the two previous commands.
