Maildroprc Automatically Delete quotawarn File in Maildir
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
# 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"` }
