[RHEL/CentOS/Scientific 6 only] Incorrect path in cron job

Note: This is applicable to Red Hat Enterprise Linux 6, CentOS 6, Scientific Linux 6. If you're running other distributions or releases, please skip this step.

iRedMail uses incorrect path (/) in user amavis's cron job, please change it to /var/spool/amavisd/quarantine/ instead. Steps:

• Execute command crontab like below to edit user amavis's cron job:

# crontab -e -u amavis

• Find below line:

# Delete virus mails which created 15 days ago.
1   5   *   *   *   find / -ctime +15 | xargs rm -rf {}

• Change the path / to /var/spool/amavisd/quarantine/ like below:

1   5   *   *   *   find /var/spool/amavisd/quarantine/ -ctime +15 | xargs rm -rf {}

• Save your changes and exit editor.

[Optional] Send an email to postmaster@ if user's mailbox is larger than or equal to 95% full

Note: This update is optional but strongly recommended, so that you, mail server administrator, can deal with mailbox quota exceed issue in time.

• Append below text into /usr/local/bin/dovecot-quota-warning.sh:

# Send a copy to postmaster@ if mailbox is greater than or equal to 95% full.
if [ ${PERCENT} -ge 95 ]; then
    DOMAIN="$(echo ${USER} | awk -F'@' '{print $2}')"
    cat << EOF | PH_DOVECOT_DELIVER -d postmaster@${DOMAIN} -o "plugin/quota=dict:User quota::noenforcing:proxy::quota"
From: no-reply@PH_HOSTNAME
Subject: Mailbox Quota Warning: ${PERCENT}% full, ${USER}

Your mailbox is now ${PERCENT}% full, please clean up some mails for
further incoming mails.
EOF
fi

• Replace 'PH_DOVECOT_DELIVER' above by the real path of Dovecot deliver program, you can find the path in the same file: /usr/local/bin/dovecot-quota-warning.sh.
  • On RHEL/CentOS/Scientific Linux/Gentoo, it's /usr/libexec/dovecot/deliver.
  • On Debian/Ubuntu/openSUSE, it's /usr/lib/dovecot/deliver.
  • On FreeBSD/OpenBSD, it's /usr/local/libexec/dovecot/deliver.

• Replace 'PH_HOSTNAME' above by your server hostname. You can get it with below command:

# hostname --fqdn
