Looking at the above settings I assume that 10240 Kb or 1000 messages
constitute the message limit.
Yes.
Is there an override on a per mailbox setting in the mailbox folder?
By mailbox do you mean users or folders? It's a per-user setting, and
it's possible to override the global quota by having userdb return a
quota field. See the SQL examples in http://wiki.dovecot.org/Quota
Do Postfix and PostfixAdmin also have their custom settings?
The problem doesn't appear to apply at the delivery stage, so it
appears to be something respected by dovecot alone.
If you want to enforce quota, use Dovecot's deliver or some other MDA
that supports Maildir++ quota. Postfix's internal MDA doesn't.
I think I got to the bottom of the problem, which probably is the
result of too much dependency on howtos and not enough RTFMing. I have
an empty blog named 'howtos considered harmful' , and this will
provide a good article.
It appears that I changed my dovecot/sql.conf from one with a separate
user_query and password_query to one with just the password_query in
conjunction with the prefetch scheme, which did not include the quota
setting. I will add concat('dirsize:storage=', quota) AS
userdb_quota to the password_query to see if it will fix the
problem.
I also have to remember to add a userdb entry to dovecot.conf and
user_query to dovecot/sql.conf just in case I opt to use dovecot's
deliver later.
The wiki states that in this case the userdb entry must come after the
prefetch entry in dovecot.conf. If this is the case I think the text
indicating the 'after' must be emphasized in the wiki. It is one of
the things that come back to bite you later.
Before
=
driver = mysql
user_query = SELECT concat('/var/vmail/', maildir) as home,
concat('maildir:/var/vmail/', maildir) as mail, 601 AS uid, 12 AS gid,
concat('dirsize:storage=', quota) AS quota FROM mailbox WHERE username
= '%u' AND active = '1'
password_query = SELECT username as user, password,
concat('/var/vmail/', maildir) as userdb_home,
concat('maildir:/var/vmail/', maildir) as userdb_mail, 601 as
userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND
active = '1'
After
=
default_pass_scheme = MD5-CRYPT
driver = mysql
password_query = SELECT username as user, password,
concat('/var/vmail/', maildir) as userdb_home,
concat('maildir:/var/vmail/', maildir) as userdb_mail, 601 as
userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND
active = '1'
[Dovecot] Repeated references to non existent users table
Dovecot keeps returning messages in the general log about a users
table, where my users table is called mailbox, based on my
postfixadmin configuration.
dovecot: Jul 10 11:37:27 Info: auth-worker(default):
sql([EMAIL PROTECTED]): SELECT home, uid, gid FROM users WHERE userid =
'[EMAIL PROTECTED]'
dovecot: Jul 10 11:37:27 Info: auth(default):
prefetch([EMAIL PROTECTED]): passdb didn't return userdb entries
I get errors stating that table postfix.users does not exist which is
right because my table is named mailbox
my dovecot-sql.conf files don't contain any references to a table named users.
dovecot.conf
=
protocol lda {
postmaster_address = [EMAIL PROTECTED]
mail_plugins = quota
log_path = /var/log/dovecot-deliver.log
info_log_path = /var/log/dovecot-deliver.log

Re: [Dovecot] pop for one ip spop for another
Dear Timo,
Thanx for your reply. But I can't immediately act on your answer.
Is it possible to enable pop only for a specific ip and enable spop for
every other ip?
I've a vserver in which an application can check mail via pop, but not
spop. And I don't like to enable pop for the outside world.
a) Firewall. Probably a better idea.
Yes, I will request to disable the ports 110 and 143 in the firewall,
but since we don't manage the firewall ourselves, I would also be able
to configure this in Dovecot.
b) Fail authentication if non-secure authentication comes from outside
world.
Clear, that's what I would like. But how? How do I differentiate? How
can I say if this, then that?
I'm using passwd:
auth_userdb = passwd
auth_passdb = pam
Do I do something within
protocol pop3 {
}
But how can I make an if/then-like statement so that I can use:
If you're using SQL as passdb this would be easy. With anything
else probably not. %r and %c variables anyway allow this
(http://wiki.dovecot.org/Variables)
It's not possible to do this I've discovered:
protocols = pop3 pop3s
disable_plaintext_auth = yes
(...)
userdb static {
args = uid=1005 gid=1005 allow_all_users=yes
disable_plaintext_auth=no
}
Here I tried to make siable_plaintext_auth different for a specific
user.
Kind regards,
Arjan.

Timo Sirainen wrote: So the real reasons for these could include temporarily using different index file paths, restoring indexes/uidlists from backups, temporarily using index files for accessing other mailbox. OK I understand your 3 points about how it actually could happen, and the ideas above as to possible causes; unfortunately we are in none of those situations. :( It was a mailbox simply created, accessed via Thunderbird and Squirrelmail all of... maybe 3 times. Nothing at all changed between the time it was working and the time it wasn't (no other mailboxes were affected). I'll keep an eye out - I created another new mailbox yesterday which will get the exact same treatment for an employee starting next Monday. If it doesn't happen again I'll just resign to calling it a random happenstance. -te -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

Re: [Dovecot] mbox vs maildir
The last time I tried to convert from mbox to maildir, things got pretty botched up, no data loss, but it wasn't pretty. :-) just because you got it wrong doesn't make it's hard. you probably didn't take enough time to get it right. Well, if you know the RIGHT way - just share it with the rest of us. I was asking Timo before and as far as I understood - there is no way of converting mbox to Maildir without losing message UIDs. And given that we already have huge mailboxes, that means that every user, connecting to the server after the conversion will need to redownload all the messages and delete all the messages in the local cache. Just imagine that user with ~5Gb of mail across 5-10 folders connect from home not-so-fast DSL line to check email and has to wait until the client rechecks all the mail No, this is not right. Exactly as Don Russell wrote - no data loss, but it isn't pretty. And this is the only reason I don't migrate to Maildir. I really want to do it, but this is not something I can do to my users. FiL

[Dovecot] Migrating subscription lists
I thought this would be relatively straightforwardI would create .subscriptions by doing an ls -1 of ~/mail. I'm running into some problems. 1) the ~/mail directories haves directories in them for 5% of the accounts! AFAIK, our mail sevice has always been UWIMAP with mbox format INBOXes, and it was my understanding that the mbox format is flat and NOT hierarchical and thus I'd have thought that ~/mail would be all folders and wouldn't have a directory with folders in it. Plus our users are not, as a rule, power/geek user that would understand even making subdirs in ~mail, so I don't know how this would have come to pass. Should this be? Or am I misunderstanding things? 2) Some people are consciously or unconsciously using the UWIMAP .mailboxlist subscription file as it is meant to be used, namely to *restrict* the folders shown. If/when I generated the Dovecot .subsbcriptions file by just doing an ls -1 of their mail directory, they will be surprised to see stuff not previously displayedthat they may very well not know they'd had.

[Dovecot] Connecting to dovecot/imap without a password
I have written a script that connects (localhost) to the dovecot/imap server and performs various maintenance on my mail, by folder. deleting old stuff, keeping the n most recent, that sort of crap, er good stuff. :-) My script is written in php (I use the various imap_* functions), and it connects to the imap server running on the same machine... is there a way to connect to the server without having to specify my user name and password? I was thinking there may be some form of implied logon if a request from user don requests to log on to user don, then there's no need for a password check, when the connection is via localhost. That way I don't have to deal with userid/password related issues. :-) Thanks

As I pointed out in a different thread about UIDVALIDITY error/warnings, we initially saw the UIDVALIDITY error/warning immediately upon upgrade to 1.0.1. I have not seen them since. I haven't seen the utime error/warning since I used that patch but I could never reproduce that problem either.
