The quota configuration doesn't really work the way you think it works.

dovecot: Aug 04 15:47:03 Info: IMAP(dario.a): Quota rule: root=  
mailbox=* bytes=209715200 (0%) messages=0 (0%)
dovecot: Aug 04 15:47:03 Info: IMAP(dario.a): Quota rule: root=  
mailbox=.mbox bytes=10485760 (0%) messages=0 (0%)


The second quota rule matches to a mailbox called .mbox. If you  
wanted it to match INBOX, you should have used INBOX there. Quota code  
sees only the virtual mailbox names, not the physical file/directory  
names.


Secondly, you can't reduce the quota for specific mailboxes. With the  
above configuration you're giving .mbox mailbox 10 MB of more space  
(so 210 MB total).


Sounds like what you want to do is change your MTA configuration not  
to allow incoming mails larger than 10 MB.

[Dovecot] Quota does not apply.

[Dario Ale]

Hello list:
I am try to run quota plugin but only works a part.

The users are virtual and his homedir and mbox are in NFS server, INDEX files 
are in local disk.

Quota only is applied to global home, if I configure a low global quota and 
sent an mail to my e-mail, quota works fine, mail is temporally deferred.

But, if I configure a high global quota and a small quota for INBOX, sent a 
mail that is more big that quota for INBOX, then quota is not applied and the 
mail is delivered to INBOX.
  
IMAP log and LDA log are equals, why I only pasted IMAP log:

But in my home I have 175M (included 13M of INBOX).

In quota table, my relared rows are:

| dario.a | quota/storage  | 183393060 |
| dario.a | quota/messages |   335 |
  
My Dovecot configuration is:

Others configurations are:

Thanks for the time and sorry for my bad english.
