dovecot - Jun 2008 - no maildirsize file being created -dovecot v1.1

Hello List,

Getting ready to setup a new dovecot sendmail squirrelmail server for
our school which is currently running on a 4 year old install of the
same, which has worked like a champ by the way.
--------------------- 
EL5
dovecot-1.1 rc10 rpm
sendmail
squirrelmail
---------------------
Problem: I can not get my dovecot 1.1 rc10(rpm) to generate an
maildirsize file in each of the users homedir. I have re-edited the
dovecot.conf file many many times but still no joy.
If I uninstall and install the default dovecot 1.0.1x rpm that ships
with EL5 i get the maildirsize file to generate correctly without a
hitch. I am wanting to use the  check_quota plugin for SM this time so I
need to get this functioning correctly.
How would I go about troubleshooting this. The only error I get in
maillog is when I log into SM I do see were dovecot tries to check for
the maildirsize file but it can not find it of course and then says "
skipping quota check",,so I think I have my dovecot.conf file setup
correctly. Dovecot is simply not generating the maildirsize file.
Following lines added to the end of dovecot.conf file:
protocol imap {
  mail_plugins = quota imap_quota
}
protocol pop3 {
  mail_plugins = quota
}
# In case you're using deliver:
protocol lda {
  mail_plugins = quota
} 
plugin {
  quota = maildir
  quota_rule = *:storage=1GB
  # 10% of 1GB = 100MB
  quota_rule2 = Trash:storage=10%%
  # 20% of 1GB = 200MB
  quota_rule3 = Spam:storage=20%%
}

,,I have reversed the above to have quota=maildir,,etc 
above the protocol directives as well and still no joy.

Sidenote: I also tried dovecot v1.1 rc5 rpm as well with the same results.
Any tips from anyone would be appreciated.

Thanks,
Barry Cisna

Set mail_debug=yes and see what gets logged.

Really? I don't remember Dovecot having any such log message. Please  
paste it entirely and exactly.

It looks to me after setting  the mail_debug=yes in the dovecot.conf
quota is looking for the maildir to be Maildir
>>(/home/superuser/Maildir, rwx). 
my install has mailboxes listed as mail>> /home/superuser/mail  ( not
Maildir)
How do i comment the quota to make a directive to correct this?
maildir=mail >>not mail=Maildir

Hi Timo,

I changed the maildir directive in my dovecot.conf as you suggested. The
maildirsize file IS created now , but, the ~/mail folder structure is
now showing all messed up for the user that logs into Squirrelmail for
example:
Before the mail_location was changed;
~/mail/Drafts,Sent,Trash,.subsciptions/.imap/Drafts,INBOX,Sent,Trash
After, mail_location = maildir:~/mail
~/mail/cur/new/tmp/.Drafts,.Sent,.Trash,dovecot.index.log,subsciptions,maildirsize/.imap/Drafts/INBOX/Sent/Trash

Notice how after the maildir directive change there are .DOT in front of
Drafts,Sent,Trash as well as no .DOT in front of subsciptions,as well as
the added cur,new,tmp directories under the ~/mail folder??

And yes this is the default EL5 install with maildir storage( not mbox).
As I stated earlier, if i simply 'rpm -e dovecot' them 'rpm -ivh
dovecot' with the default install of the dovecot rpm that shipps with
EL5 everything comes up correctly as far as quotas for dovecot,
Squirrelmail,etc.
I think I may just stick with the default dovecot1.0.1.2-rc15.el rpm
that ships with EL5 for now. I'm afraid of other underlying problems i
may find as I we start using dovecot v1.1 when school starts then I will
be in trouble!
Another sidenote: After installing dovecot1.1 rpm dovecot appears to
start fine with no errors,,but it is not actually listening on port 143
by doing an nmap localhost. I had to change
listen = [::]
to
listen = *
then restart dovecot,then dovecot was listening on port 143 as it
should.

Thanks for the help,

Hi Timo,

Thanks for the info. You are exactly right ,,after I done some
researching. by default the Fedora and El distros setups up mail folders
in mbox format. My Bad. I was always under the impression default was
maildir.I have used sendmail>Procmail>dovecot>squirrelmail for my new
setup same as the last email server setup.I found that sendmail seems to
be much less CPU intensive than postfix,or I did not have the config
correctly as postfix was easy to setup but really choked our email
server when a secretary " bulk emailed" everyone in the school
district.
I have learned a lot about this in the last couple days. I thought I
knew a little bit about this,but obviously I didn't know a thing. I am
going to go with the default dovecot rpm that ships with EL5 1.0.1x as
this does what all I need to have done. My main concern is the
check_quota plugin available for Squirrelmail works,and with the dirsize
quota directive put into dovecot.conf this is working very slick, and
appears to be reporting very accurately.Now hopefully some teachers will
not end up with 1GB mail folders!! and complaining the mail server is so
slow when they check their email via Squirrelmail at home!
Thanks again for steering me straight!

Take Care,

Barry Cisna
