Hi

Has anyone experienced this issue? I'm not able to debug it.

Config, users, permissions, etc are the same as in the previous version, where it worked without problems.

If anyone can help it would be appreciated, I don't know what else look.

Thanks and best regards

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 $USER -o "plugin/quota_rule=*:bytes=%$"

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?
