[Dovecot] Dovecot and quota enforcement - only reporting?
I'm currently setting up postfix and dovecot with virtual users (mysql), imap, and quotas. I'm setting the quotas using mysql.
I have quotas working correctly, and I can telnet into the imap server, and submit . getquotaroot inbox and get back valid quota information. I get a maildirsize file in the Maildir directory. Very cool.
When I delete mail and expunge it, the quota updates. However, inbound email doesn't appear to update the quota.
Two questions, probably related: What causes the quota (which I presume is the maildirsize file) to update? Is there any actual quota enforcement, or just reporting? Because if I send mail to an account, even if it currently reporting (via maildirsize or . getquotaroot) that the user is over quota, they still can send and receive email.
Thanks!

Just checking to see if there are any insights here.

How are you delivering your mails to mailboxes? If you don't use dovecot's deliver quota won't get updated (unless you use filesystem quota)

Wow, that clearly shows I'm not really sure what I'm doing, as I don't really understand the question.
I'm running Postfix, with Dovecot on top. Uses check mail via Outlook/IMAP, or Web/Squirrelmail.

Postfix is an MTA (Mail Transfer Agent). It has its own built in 'Delivery Agents' - LDA (Local Delivery Agent) and VDA (Virtual Delivery Agent). A barebones postfix install will use one of these.
Dovecot is a POP/IMAP server - it allows clients to access existing messages located on a filesystem somewhere.
'Deliver' is the act of the final placement of an email message to the final destination filesystem.
It sounds like you have some reading to do...
Here is the dovecot wiki page on dopvecots 'Deliver' program:

Still no answer to my original question of what exactly updates maildirsize? Is that also the dovecot LDA?

I'm using virtual delivery in postfix (mysql users). Postfix is running the default delivery agent: mailbox_command =
So the only way to get quota enforcing with Dovecot is to have Postfix use the dovecot LDA?
And from the wiki it indicates:
dovecot_destination_recipient_limit = 1 virtual_mailbox_domains = your.domain.here virtual_transport = dovecot
but I'm currently running multiple domains. How does virtual_mailbox_domains configure to handle that?

- Dovecot LDA for newly delivered mails
- Dovecot IMAP for messages saved/copied via IMAP client

Yes, the only way to enforce quota for newly delivered mails is to deliver mails via LDA capable of enforcing the quota. :)
(It doesn't have to be Dovecot LDA though, there are other LDAs that understand Maildir++ quota too. Dovecot LDA is recommended though.)

Thanks, that perfectly explains why I haven't been able to figure out what makes maildirsize update.

Excellent. Now off to figure out whether I'll break anything by changing it! :-) Is it different between virtual users (mysql using a dovecot-mysql.conf file) and local users?
