Owner of an over quota account just got an email when some emails were
deleted from it (no date on that email though, don't understand why)

Don't know what resolved the issue, I did following changes recently,

chmod 700  /usr/local/bin/quota-warning.sh

Edit , 90-quota.conf as below,

service quota-warning {
executable = script /usr/local/bin/quota-warning.sh
# use some unprivileged user for executing the quota warnings
user = root
unix_listener quota-warning {
mode = 0666
user = root
group = root
   }
  }

/etc/init.d/dovecot restart

ls -al /var/run/dovecot/quota-warning
srw-rw-rw- 1 root root 0 Mar 24 20:23 quota-warning

Thanks,
