==Maintainer==
This contrib has been developed by [[User:Knuddi|Jesper Knudsen]] from [http://smeoptimizer.swerts-knudsen.dk SME Optimizer]
==Maintainer==
==Details==
We have now added it to the contribs repo and are updating it for v10.
It needs the smeserver-dovecot-extras rpm
https://wiki.contribs.org/Dovecot-extras
==Version==
{{ #smeversion: smeserver-unjunkmgr }}
==Description==
==Description==
==Installation==
==Installation==
You can install this contribs by yum with the following command. You should use this method as you will have always the newest version.
yum install perl-MIME-Lite --enablerepo=smecontribs
<tabs container>
yum install mrtg --enablerepo=base
<tab name="For sme10">
yum install --enablerepo=smecontribs smeserver-unjunkmgr
</tab>
<tab name="For sme9">
yum install --enablerepo=smecontribs smeserver-unjunkmg
and then
expand-template /etc/crontab
expand-template /etc/httpd/conf/httpd.conf
/etc/rc.d/init.d/httpd-e-smith restart
or
signal-event post-upgrade; signal-event reboot
</tab>
</tabs>
====Upgrading====
yum upgrade --enablerepo=smecontribs smeserver-unjunkmgr
====Uninstall====
You can simply remove the package again with the usual yum command.
yum remove smeserver-unjunkmgr
==Configuration==
If you are uninstalling version 1.0.0-1 you also need to also expand templates.
====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):
/sbin/e-smith/db configuration setprop unjunkmgr adminemails <no|yes>
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):
/sbin/e-smith/db configuration setprop unjunkmgr useremails <no|yes>
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)?
/sbin/e-smith/db configuration setprop unjunkmgr unjunkhost <hostname|IP address>
The summary emails contain a link to an web page where emails can be unjunked (released to he inbox). These URLs cann, by default, only be seen from the local network (IP ranges defined in Local Network in the server-manager) but if you want this to be accessible from remote networks (public access) this can be done via (default: yes):
/sbin/e-smith/db configuration setprop unjunkmgr LocalOnly <no|yes>
expand-template /etc/httpd/conf/httpd.conf
systemctl restart httpd-e-smith
====Statistics====
The UnJunk Manager also collects statistics on the emails passing through the mail server. This is accessible from:

expand-template /etc/httpd/conf/httpd.conf

An additional feature of the UnJunk Manager is to send the collected statistics to a central statistics central at http://central.swerts-knudsen.dk. The gathering of data is not stressful for the server and the data sent is not sensitive (well in my opinion) and consists of:
An additional feature of the UnJunk Manager is to send the collected statistics to a central statistics central at http://central.swerts-knudsen.dk. The gathering of data is not stressful for the server and the data sent is not sensitive (well in my opinion) and consists of:
* Amount of emails scanned
* Number of spam infected (tagged and rejected) or virus infected emails (if virus found the ClamAV name)
* The version of SME server used
* Public IP address of server (used to plot in Google Maps on central.swerts-knudsen.com)
Should you want to disable this functionality then this can obviously be done:
Should you want to disable this functionality then this can obviously be done:
/sbin/e-smith/db configuration setprop unjunkmgr statsclient <disabled|enabled>
/sbin/e-smith/db configuration setprop unjunkmgr statsclient <disabled|enabled>
====SpamAssassin bayes filters====
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.
config setprop spamassassin UseBayes 1
config setprop spamassassin BayesAutoLearnThresholdSpam 4.00
config setprop spamassassin BayesAutoLearnThresholdNonspam 0.10
expand-template /etc/mail/spamassassin/local.cf
sa-learn --sync --dbpath /var/spool/spamd/.spamassassin -u spamd
chown spamd.spamd /var/spool/spamd/.spamassassin/bayes_*
chown spamd.spamd /var/spool/spamd/.spamassassin/bayes.mutex
chmod 640 /var/spool/spamd/.spamassassin/bayes_*
config setprop spamassassin status enabled
signal-event email-update
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.
db configuration setprop spamassassin MessageRetentionTime 15
signal-event email-update

====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.
Follow the guide for [[Virus:Additional_Signatures|Additional Virus Signatures]] to do that.

You will need to change the “$debug = 0;” to “$debug = 1;” in the configuration section of the /usr/local/unjunkmgr/spamreminder.pl file. Then launch the reminder manually with:
You will need to change config via:
/sbin/e-smith/db configuration setprop unjunkmgr useremails no
/sbin/e-smith/db configuration setprop unjunkmgr adminemails yes
Then launch the reminder manually with:

All the summary emails will now be sent to “admin”.
