Hi All,

Since upgrading to RHEL7 and dovecot-2.2.36-8.el7.x86_64 we're not able to get quota warnings work.

We get the error "User initialization failed: Failed to initialize quota: Invalid quota root quota: Invalid rule *:bytes=: Invalid bytes limit:"

This is the quota-warning script:


#!/bin/sh
#Variables
PERCENT=$1
USER=$2
FECHA=`date '+%b %d %H:%M:%S'`

#Logueo del evento
echo "$FECHA lda($USER): Quota: Executing warning: quota-warning $PERCENT $USER" >> /var/log/dovecot/dovecot.log
logger -p local1.notice -f /var/log/dovecot/dovecot.log "$FECHA lda($USER): Quota: Executing warning: quota-warning $PERCENT $USER"

This is 90-quota.conf

plugin {
  quota = maildir:_backup:ns=
}

plugin {
  quota_exceeded_message = El espacio asignado para el almacenamiento del correo del destinatario ha superado su capacidad total. Por ello, el correo que usted intenta enviar no se puede entregar al destinatario.
  quota_warning = storage=70%% quota-warning 70 %u
  quota_warning1 = storage=90%% quota-warning 90 %u
  quota_warning2 = storage=95%% quota-warning 95 %u
  quota_warning3 = storage=99%% quota-warning 99 %u
}

service quota-warning {
  executable = script /etc/dovecot/scripts_notification_quota/quota-warning.sh
  user = vmail
  unix_listener quota-warning {
    user = vmail
  }
}

Getting user attibutes and quota with doveadms works right:

# doveadm user user@domain
field   value
uid     508
gid     503
home    /buzones/externos/4/215283255776546
mail    maildir:/buzones/externos/4/215283255776546/Maildir
quota_rule *:bytes=2147483648
# doveadm quota get -u user@domain
Quota name Type      Value   Limit                                                                                                    %
_backup    STORAGE 1153093 2097152                                                                                                   54
_backup    MESSAGE   44347       -  

It also works fine with ldapsearch

# ldapsearch -x -D "cn=mail_admin,cn=users,dc=domain,dc=es" -w ********** -b "dc=domain,dc=es" -h ldap.host mail=user@domain mailquotasize
# extended LDIF
#
# LDAPv3
# base <dc=domain,dc=es> with scope subtree
# filter: mail=user@domain
# requesting: mailquotasize
#

# user@domain, users, domain.es
dn: cn=user@domain,cn=users,dc=domain,dc=es
mailquotasize: 2147483648

I've been googling but I can't find where the problem may be. Can you please help me?
