Maildroprc Automatically Delete quotawarn File in Maildir

Jan 12th, 2010 | email, filter, postfix, smtp | No Comments

This is the Ugly workaround

Postfix master.cf setting

maildrop  unix  -       n       n       -       -       pipe
  flags=ODRhu user=vmail argv=/usr/bin/maildrop -w 90 -d ${recipient} ${user} ${domain}

With this setting maildrop wil warn user if their Maildir reach 90% of quota and send warning to user

The problem is, even if user emptying their maildir, users wil always get warning because quotawarn is still in Maildir

[vchkpw] quotawarn question

#
MAILHOME="/var/data/postfix"
DOMAIN="$2"
USER="$1"

QUOTA=`echo "$MAILDIRQUOTA" | cut -f 1 -d S`
USAGE=`du -sb "$MAILHOME/$DOMAIN/$USER/" | awk '{print $1}'`
PERCENT=`echo "$QUOTA * 90/100" | bc`

if ( "$USAGE" < "$PERCENT" )
{
        `/bin/rm -f "$MAILHOME/$DOMAIN/$USER/quotawarn"`
}

Shaping Layer 7 Application on centos 4.7 (iptables + l7 + IMQ + tc/HTB)

Jul 3rd, 2009 | bash, c, filter, iptables, kernel, linux, modules | 4 Comments

Pertama download kernel source kernel 2.6.26.

# wget -t0 -c http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.26.tar.bz2

Download iptables 1.4.1 source.

# wget -t0 -c http://www.netfilter.org/projects/iptables/files/iptables-1.4.1.tar.bz2

Download patch l7 + IMQ (untuk kernel dan iptables) yg sudah saya modifikasi jadi satu bundle.

Extract ,patch dan compile kernel source(to RPM)
