[Dovecot] quota warning email to user

[upen]

Hi,

I am trying to use Quota in dovecot-2.0.11. I find as a sender(same
user a receiver) I receive an email that receiver's Quota is exceeded
, and receiver's mailbox is full . This is good, however the receiver
whose MB is full isn't getting any quota-warning. Configuration is as
below,


dovecot -n
# 2.0.11: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.35-gentoo-r8 x86_64 Gentoo Base System release 1.12.14 ext4
auth_mechanisms = plain login
listen = *
mail_location = maildir:/nfs1/mail/%u
mail_plugins = " quota"
passdb {
  args = *
  driver = pam
}
plugin/quota = maildir:User quota
plugin/quota_rule = *:storage=5M
plugin/quota_rule2 = Trash:storage=+1M
plugin/quota_rule3 = Junk:storage=+1M
plugin/quota_warning = storage=95%% quota-warning 95 %u
plugin/quota_warning2 = storage=80%% quota-warning 80 %u
service quota-warning {
  executable = script /usr/local/bin/quota-warning.sh
  user = dovecot
}
ssl_cert = </etc/postfix/ssl/smtpd.pem
ssl_cipher_list = ALL:!LOW:!SSLv2
ssl_key = </etc/postfix/ssl/smtpd.pem
userdb {
  driver = passwd
}
protocol imap {
  mail_plugins = " quota imap_quota"
