Step 6: Install And Configure gnarwl

Let's install gnarwl:

apt-get install gnarwl

Now let's configure gnarwl.

First we're going to back up the original configuration file and replace it with a new one.

mv /etc/gnarwl.conf /etc/gnarwl.conf.bck

Now we create the new conf file:

vi /etc/gnarwl.conf

And insert the following:

map_sender $sender
map_receiver $recepient
map_subject $subject
map_field $begin vacationStart
map_field $end vacationEnd
map_field $fullname cn
map_field $deputy vacationForward
map_field $reply mail
server localhost
port 389
scope sub
login cn=admin,dc=example,dc=tld
password secret
protocol 0
base dc=example,dc=tld
queryfilter (&(mailAutoreply=$recepient)(vacationActive=TRUE))
result vacationInfo
blockfiles /var/lib/gnarwl/block/
umask 0644
blockexpire 48
mta /usr/sbin/sendmail -F $recepient -t $sender
maxreceivers 64
maxheader 512
charset ISO8859-1
badheaders /var/lib/gnarwl/badheaders.db
blacklist /var/lib/gnarwl/blacklist.db
forceheader /var/lib/gnarwl/header.txt
forcefooter /var/lib/gnarwl/footer.txt
recvheader To Cc

Change the default to your actual configuration.

Last but not least execute the following command to make gnarwl work:

chown -R vmail:vmail /var/lib/gnarwl/

This concludes the gnarwl configuration. 


Step 7: Bringing It All Together And Making It Work

The following command will put into effect the configurations we made before:

/etc/init.d/apache2 stop
/etc/init.d/apache2 start
/etc/init.d/dovecot stop

First we restart postfix:

/etc/init.d/postfix start

We need to do this in order to have the following directory created:


Now we need to make new ssl certificates for Dovecot:

dpkg-reconfigure dovecot-common

If the directory /var/run/dovecot and /var/run/dovecot/login don't exist the reconfigure command above will produce errors complaining that the directories do not exist. In that case just create them. And re-run the command above.

Now we can start Dovecot:

/etc/init.d/dovecot start

You can now browse to http://example.tld/phamm

Log in with the user admin and your OpenLDAP password.

You should now be able to create domains and users.

One more thing: since phamm doesn't actually delete users and / or domains, we need to enable the that comes with phamm.

cp /var/www/tools/ /home/vmail/.

Edit the file to your settings, but set the  BINDDN to BINDDN="cn=admin,dc=example,dc=tld" for the script to work correctly.

Now we add a crontab to run the script periodically:

crontab -e

And insert the following:

30 * * * * /home/vmail/

Well everything should be up and running now.
