Quota - Invalid bytes limit

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"//
//
//cat << EOF | /usr/libexec/dovecot/dovecot-lda -d $USER -o 
"plugin/quota_rule=*:bytes=%$"//
//From: postmaster at domain//
//Subject: Alerta de Capacidad//
//Date: `date`//
//
//El espacio asignado para el almacenamiento de su correo ha superado el 
$PERCENT% de su capacidad total. Por ello, se recomienda que elimine 
correos y/o vacie la papelera para liberar espacio.//

-----------------------------

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 at 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 at 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 at domain 
mailquotasize//
//# extended LDIF//
//#//
//# LDAPv3//
//# base <dc=domain,dc=es> with scope subtree//
//# filter: mail=user at domain//
//# requesting: mailquotasize//
//#//
//
//# user at domain, users, domain.es//
//dn: cn=user at 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?
