I'm using today's hg checkout of 1.2 beta 4

Hi Ralf, did they report so , or is it real, sometimes users are failing with expunge options of their client

Along a similar line: with 1.2 beta 4 I had today a user who according to deliver was over quota:

Apr 1 08:00:27 apollo dovecot: deliver(user1): sieve: msgid=<20090401060005.0821B1E82B0@hostxxx>: failed to store into mailbox 'INBOX': Quota exceeded (mailbox for user is full)

but the IMAP command reported correctly what I also found in the maildirsize file (in userdb the configured limit was 1000M, his actual INBOX size was below 600M):

1048576000S 557816894 10852

The relevant sections from dovecot.conf are

protocol imap { mail_plugins = quota imap_quota zlib acl imap_acl }

protocol lda { mail_plugins = sieve quota acl }

plugin { quota = maildir:Quota quota_rule = *:storage=500MB quota_rule2 = Trash:ignore }

With that config the quota for ALL users seems to be at 500M not taking into account userdb overrides. Or is that the effect of a wrong configuration, e.g. quota = maildir:Quota should become quota = maildir:User Quota ?

Are you calling deliver with -d parameter? If not, the userdb lookup is not done in that case. If you are, set mail_debug=yes and paste the logs when this happens.

I did not call deliver with the -d parameter. I just added that right now

Sorry for the trouble. I did recheck that I already had called deliver using -d ${recipient}. That seems not to be the problem.

I made several experiments with quota settings and userdb while mail_debug was on. Here are my findings:

After changing /etc/userdb and modifying my userdb_quota_rule=*:storage=200M with an editor the IMAP GETQUOTAROOT does immediately report the changed value. The ~user/Maildir/maildirsize content does however not change and according to the maillog output the quota calculation is done based on the contents of that file.

If I do delete that file after changing the contents of the users INBOX the file gets regenerated with the contents from the quota rule (i.e. 900MB, see below) and not with the value from the userdb (200M)

If then I do another IMAP GETQUOTAROOT the correct value is reported again (200M) and the contents of ~user/Maildir/maildirsize is changed to that value as well.

This is however not the only finding. I manipulated further my userdb quota and did set it to 90MB. Shortly after that another user (Quota 900MB) received a mail. The debug output for that mail delivery:

dovecot: deliver(user2): Quota warning: bytes=89653 2480 (95%)...

indicates that my settings were used instead for quota calculation. The maildirsize content for that user was however still at 900MB, not 90MB.

I am now puzzled what should happen when and whether I am looking to the correct indicators for problems. I could make the log file available, I would however prefer to generate a logfile where I get told what to try in what order to get more information from that logfile.

It could be that the bug is somewhere in my config, which I do post again for reference (excerpt), but I cannot see what might be wrong with it.

protocol imap { mail_plugins = quota imap_quota zlib acl imap_acl }

protocol lda { mail_plugins = sieve quota acl } auth default { mechanisms = gssapi gss-spnego login plain passdb pam { } userdb passwd-file { args = /etc/userdb } user = root } plugin { quota = maildir:Quota quota_rule = *:storage=900MB quota_rule2 = Trash:ignore }

The limits in maildirsize file are ignored by Dovecot as long as you defined quota_rules. So don't bother looking at them.

Thanks, that explains why my expectations about its contents were not met.

It's again beginning to sound like deliver isn't doing a userdb lookup and getting the userdb_quota_rule.

Yes, I verified by looking at the time stamps that you are right. The userdb seems not to be reread when using deliver. From the debug mail log output I do see however that at least deliver is used to store the mail:

postfix/local[27389]: ... status=sent (delivered to command: /usr/libexec/dovecot/deliver)

It looks like something with my combination of postfix and dovecot is not working as I do expect it. I will check my configs again and hope to find the reason.

Does maildirsize file show any such deletions? Like lots of lines / large numbers in lines beginning with "-"?

I did a few tests and it seemed to work correctly. Also the Maildir++ quota code hasn't really changed since v1.1 (quota configuration structures changed somewhat though).

It seems my users need to log out and back in again to get the correct quota info displayed within Squirrel Mail

Hi Ralf, thats maybe by design of squirrel after all a refresh is a must have i think for new calculate quota as far i remember its the same with a courier install here
