apt-get install libsasl2-2 sasl2-bin libsasl2-modules

The postfix configuration requires the following update in/etc/postfix/main.cf.

# add permit_sasl_authenticated for SASL support
smtpd_recipient_restrictions =
        permit_mynetworks,
        permit_sasl_authenticated,
        reject_unauth_destination,
        check_policy_service inet:127.0.0.1:60000

# add these options
smtpd_sasl_auth_enable = yes
smtpd_sasl_authenticated_header = yes
broken_sasl_auth_clients = yes
smtpd_sasl_security_options = noanonymous

Create /etc/postfix/sasl/smtpd.conf with this content

pwcheck_method: saslauthd
mech_list: plain login

Then create directory /var/spool/postfix/var/run/saslauthd

 mkdir -p /var/spool/postfix/var/run/saslauthd

Set permissions

dpkg-statoverride --add root sasl 710 /var/spool/postfix/var/run/saslauthd

And add postfix user to group sasl

adduser postfix sasl

/etc/default/saslauthd Requires some modifications

START=yes
OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd -r"

Finally restart some services.

/etc/init.d/saslauthd restart
/etc/init.d/postfix restart

Upgrading from debian etch

If you are upgrading and getting permission errors then you can fix these by berforming the steps above where permissions for /var/spool/postfix/var/run/saslauthd are set and the user group sasl is updated.

SASL authentication failure: Password verification failed
SASL PLAIN authentication failed: generic failure
SASL authentication failure: cannot connect to saslauthd server: Permission denied
SASL LOGIN authentication failed: generic failure

I only needed to update my PHP4 to PHP5, unpacked the installation package to the web root for the virtual host I created for roundcube, created a new mysql database and started the installation procedure.

Though it is still only a 0.3 version it has quite some impressive set of features. Of course due to its Web 2.0 nature it is a little bit slower than squirrel mail that I used earlier!

1. Frequent logging file reports
2. Monthly backup
3. Moving backup files to some external storage service

Due to my pretty constrained time budget only now I was able to spend some hours on getting some task done.

For Frequent logging file reports I added logwatch to my system, customized it in /etc/logwatch/conf/logwatch.conf.

# Default person to mail reports to.  Can be a local account or a
# complete email address.
MailTo = recipient@domain
# Default person to mail reports from.  Can be a local account or a
# complete email address.
MailFrom = Logwatch

# If set to 'Yes', the report will be sent to stdout instead of being
# mailed to above person.
Print = No

I added logwatch to my daily cron jobs in /etc/cron.daily/logwatch

test -x /usr/share/logwatch/scripts/logwatch.pl || exit 0
/usr/share/logwatch/scripts/logwatch.pl

I added a /etc/cron.monthly/backup script for performing monthly backups of important system files

outputFolder=/var/tmp/backup
now=`date +%Y%m%d%H%M`
hostname=`hostname`
outputFolder=$outputFolder/$hostname/$now

if [ -d $outputFolder ]
then
        echo "Backup has alread run on '$hostname'  for '$now'"
        exit 1
else
        mkdir --parents --verbose $outputFolder
fi

echo backup...
options=-cvvz
tar $options --file=$outputFolder/backup.tar.gz --exclude=/var/cache/* --exclude=/var/spool/* --exclude=/var/lock/* --exclude=/var/run/* --exclude=/var/tmp/* --exclude=/var/log/* /var /etc /home 1>$outputFolder/backup.log

echo "Backup for $hostname ready at $outputFolder/backup.tar.gz" | mail -s "Backup completed for $hostname `date`" recipient@domain
