dovecot - Nov 2009 - quote warning not being triggered (yet again)

I'm using 1.2.6 with the managesieve patch and maildir++ quotas (via
the maildirsite file). Again, I found that the quota warning is not
bering triggered.

Testing via:
smtp-source -4 -f sender at charite.de -t recipient at charite.de -m 1 -l
1000000 -C 1 mail.charite.de:submission

recipient at charite.de being a mailbox with a 10.0 MB limit.
I attached dovecot -n and the quota warn script.

Was ist los?
===========
Wir haben festgestellt, dass Ihre Mailbox auf dem Server
postamt.charite.de das erlaubte Gr?ssenlimit zu mindestens
${MAIL_QUOTA_PERCENT}%
aussch?pft. 

D.h. die maximal erlaubte Gesamtgr??e der Mailbox wird bald erreicht
sein oder ist es sogar schon!

Was kann ich nun tun?
====================
Bitte schaffen Sie Platz in Ihrer Mailbox, indem Sie die Mails z.B.
auf dem Server l?schen oder in Ihre lokale Mailbox auf Ihrem eigenen
Rechner verschieben und so wieder Platz auf dem Server schaffen!

Wie kann ich die F?llung meines Postfaches auf dem Server ?berpr?fen?
====================================================================
Sie k?nnen die F?llung Ihres Postfaches ?ber Webmail

  https://webmail.charite.de/

leicht ?berpr?fen:   Nach dem Anmelden erscheint im linken Rahmen unter
Ihrer Ordnerliste ein Link namens "Ordnergr??en". 

Sie k?nnen in Webmail ggf. auch gleich die Mails l?schen (vergessen
Sie hinterher nicht, den Papierkorb / Trash Ordner zu leeren!).

Warum ist mein Postfach ?berhaupt so voll?
=========================================
Dies kann z.B. passieren, wenn Sie mehrere Rechner nutzen um Ihre Mail
zu lesen und statt des IMAP Protokolls das POP3-Protokoll mit der
aktivierten Option "Leave Mail on Server" / "Mail auf Server
belassen"
in Ihrem Mailprogramm verwenden.

Oft wird auch vergessen, da? der Ordner mit den "Gesendeten Objekten"
(Sent Folder/Sent Items) zum Gr??enlimit der Mailbox z?hlen.

Besondere Platzfresser sind Mails mit gro?en Anh?ngen, wie z.B.
PowerPoint-, PDF- oder Bilddateien -- insbesondere im "Sent" Ordner!

Wer sind meine Ansprechpartner?
==============================
Sie k?nnen uns unter email-admin at charite.de oder telefonisch unter
450-570600 erreichen.

Mit freundlichen Gr??en

At least one problem is that the quota_warnings should be listed in reverse
order. I think it should still trigger at least one of them though.. I probably
should change those to be sorted internally.

Also try setting mail_debug=yes and seeing what it logs. Then it logs each time
it attempts to execute quota warning: "quota: Executing warning: %s".
