====Email Notifications====
 +
The UnJunk Manager sends out the summary email every Friday at 1PM to all users with emails stored in their junkmail folder. If you wish the admin account to get copied on all these user emails then this can be enabled/disabled with (default: no):
   −
The SpamAssassin learning requires that the SpamAssassin bayes filters have been enabled though. How this is done can be read at http://wiki.contribs.org/Email#Setup_Blacklists_.26_Bayesian_Autolearning or through these few shell commands.

If you just want to use the UnJunk Manager to gather statistics and not send out any summary emails to the users you can disable this functionality with (default: yes):
−
config setprop spamassassin BayesAutoLearnThresholdSpam 4.00
  −
config setprop spamassassin BayesAutoLearnThresholdNonspam 0.10
  −
expand-template /etc/mail/spamassassin/local.cf

  −
config setprop spamassassin status enabled
  −

      +
/sbin/e-smith/db configuration setprop unjunkmgr useremails <no|yes>
   −
Personally I also think that the default 90 days of retention for emails in the junkmail folder is way to long - who bothers to look at 90 days old emails anyways? I run with 15 days of retention on all my installations.
+
How do I configure the UnJunkMgr to use an IP address or a different hostname rather than the primary domain name when it sends out the weekly overview (default: domainname)?

====Unofficial ClamAV signatures====
  −
I would also recommend to install the script that downloads all the unofficial ClamAV signatures as these detects not only virus but equally importantly various kinds of malware and spam.

===How do I avoid the admin emails?===
  −
You unfortunately have to change a few lines of code to avoid these. Open a shell on the system you install the contrib on and open /usr/local/unjunkmgr/spamreminder.pl with your favorite editor.
  −
  −
Find the line (around line 35):
  −
my $admin_email_addr = 'admin';
  −
and change to
  −
my $admin_email_addr = "";

This contrib has not yet been created in the bugtracker so just send an email to mailto:contribs@swerts-knudsen.dk

===Recent fix to know problem:===
  −
How do I configure the UnJunkMgr to use an IP addres rather than the primary domain name when it sends out the weekly overview?
  −
  −
There are no configuration options to alter this so you need to fix it in the code - not so hard though.
  −
open /usr/local/unjunkmgr/spamreminder.pl with your favorite editor ad go to line 49 where $root_url is defined.
  −
  −
Let assume that the local IP address of the server is 192.168.1.2
  −
  −
change the original line 49:
  −
  −
<nowiki>my $root_url = sprintf ("http://%s/unjunkmgr",$domain_name);</nowiki>
  −
  −
to
  −
  −
<nowiki>my $root_url = sprintf ("http://%s/unjunkmgr",'192.168.1.2');</nowiki>
