Gestione fetchmail da Postfixadmin

Installazione

• Installare le dipendenze necessarie:

sudo apt-get install liblockfile-simple-perl

• Installare lo script

sudo cp /usr/share/doc/postfixadmin/examples/fetchmail.pl /usr/local/bin/
sudo chmod +x  /usr/local/bin/fetchmail.pl

• Patcharlo

sudo  sed -i 's/etc\/mail/etc/g' /usr/local/bin/fetchmail.pl

• Per Debian 10, se ci sono errori SSL, ad esempio per certificato non valido, non prosegue, perchè usa ssl di default. Per disabilitare l'uso di ssl di default

vi /usr/local/bin/fetchmail.pl

...
    $cmd.=" sslfingerprint \"$sslfingerprint\"" if ($sslfingerprint);
    $cmd.=" ".$extra_options if ($extra_options);
    $cmd.=" sslproto ''";
...

Configurazione

• Creare il file di configurazione:

sudoedit /etc/postfixadmin/fetchmail.conf

$db_type = 'mysql';
$db_host="localhost";
$db_name="postfixadmin";
$db_username="postfixadmin";
$db_password="CHANGE_ME!";

Creazione directory run

Debian 10

• Debian 10 non ha rc.local, impostare tmpfile.d:

vi /etc/tmpfiles.d/fetchmail.conf

d /var/run/fetchmail 0755 fetchmail	nogroup

• Crearla la prima volta:

systemd-tmpfiles --create

Debian < 10

• Aggiungere la creazione della directory run:

sudoedit /etc/rc.local

# By default this script does nothing.

mkdir -p /var/run/fetchmail
chown -R fetchmail:nogroup /var/run/fetchmail

exit 0

• Crearla:

sudo /etc/rc.local 

Test

• Testare

sudo -u fetchmail /usr/local/bin/fetchmail.pl

sudo tail -f /var/log/syslog

Cron

• Impostare il cronjob

sudoedit /etc/cron.d/postfixadmin-fetchmail 

# Run postfixadmin fetchmail wrapper every 5 minutes. So it is useless to set poll
# interval less than 5 minutes in postfixadmin gui !
#min    hours   DayOfMonth      Month   DayOfWeek user      command
*/5     *       *               *      *          fetchmail /usr/local/bin/fetchmail.pl > /dev/null
