[Dovecot] loop when I enable
Hello!
I have a nasty problem with a loop when I enable quota_warning. The mailbox fills up with thousands of email within seconds. This happens only with mbox'es retrieved with POP3.

The problem occurs when I add the following to dovecot.conf:
quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u quota_warning3 = -storage=100%% quota-warning below %u # user is no longer over quota
The script executed looks like this:
#!/bin/sh PERCENT=$1 USER=$2 cat << EOF | /usr/libexec/dovecot/dovecot-lda -d $USER -o "plugin/quota=maildir:User quota:noenforcing" From: support@anup.de Subject: Mailbox Quota-Warnung
Ihre Mailbox ist jetzt zu $PERCENT% belegt. EOF
What can I do? I wonder if there some solution with namespaces possible maybe?
Thank you!

Just because quota isn't enforced, it doesn't mean that the quota warnings aren't executed. You need to disable quota entirely (e.g. -o plugin/quota= might work, although it requires a somewhat new version).

Now I have -o plugin/quota= in the script. That seems to avoid the loop, but the user also does not get a quota-warning.

quota_warning3 = -storage=100%% quota-warning below %u # user is no longer over quota
