With 2.0.18 I was using a quota warning script like this:

plugin { ...

Quota

quota = maildir quota_rule = INBOX.Trash:storage=+2048M quota_warning = storage=99%% quota-warning 99 %u quota_warning2 = storage=95%% quota-warning 95 %u quota_warning3 = storage=90%% quota-warning 90 %u quota_warning4 = storage=85%% quota-warning 85 %u }

der schickt die Quota warnmails

service quota-warning { executable = script /usr/local/scripts/quota-warning2.1 user = root unix_listener quota-warning { mode = 0666 user = vmail group = users } }

-rwxr-xr-x 1 root staff 3081 Feb 28 16:56 /usr/local/scripts/quota-warning2.1

But now I'm gettting this in my log: Feb 28 19:19:03 postamt quota-warning2(phxxxpsu): writing message failed Feb 28 19:19:03 postamt dovecot: quota-warning: Fatal: master: service(quota-warning): child 15065 returned error 1 Feb 28 19:40:13 postamt quota-warning2(lxxxve): writing message failed Feb 28 19:40:13 postamt dovecot: quota-warning: Fatal: master: service(quota-warning): child 3318 returned error 1

What is failing here?

#!/bin/sh

Should be run by the Local Delivery Agent

#set -x

SCRIPT_NAME="quota-warning2"

MAIL_TO=$2 MAIL_FROM="postmaster@charite.de" MAIL_QUOTA_PERCENT=$1 MAIL_SUBJECT="Ihre Mailbox ist zu "$1"% voll!"

BIN_CAT="/bin/cat" BIN_DATE="/bin/date" BIN_HOSTNAME="/bin/hostname" BIN_LOGGER="/usr/bin/logger" BIN_MV="/bin/mv" BIN_STAT="/usr/bin/stat"

set misc values

set mail value

MAIL_DATE="${BIN_DATE} '+%a, %d %b %Y %T %z (%Z)'" MAIL_MESSAGE_ID="${BIN_DATE} '+%Y%m%d%H%M%S'@${HOSTNAME}" #To: ${MAIL_TO}

write out message

some warning in german

log warning attempt
