I'm trying to configure dovecot to handle quota limits.

I have followed a guide and configure the right steps. I even compared them with our current mailserver.

The problem is, Dovecot doesn't write to the quota2 table in our database. I have checked both the mysql logs and the maillog file (dovecot log location), but I don't see any errors about the quota. All other queries are working perfect. The quota in the users table is also fetched.

Does anyone have a clue? What am I missing?

Dovecot -n output:

UPDATE 2 (thanks to Fox): The quota is updating. However, the mail doesn't seem to block when I am over my limit. Current limit is 10kb, which I exceeded after I sent a couple of messages. Missing any setting?

  • Try to set mail_debug to yes and post the output here. See wiki2.dovecot.org/Logging

A little guess based on comparing your configuration to my.

CONCAT('maildir:storage=',quota) AS quota should rather be CONCAT('maildir:storage=',quota) AS quota_rule

I think you are overriding the quota= setting from configuration, by per-user entry. (But I am no expert, so really just a guess)

Do not remember why, but my quota query is concat('*:storage=', quota) as quota_rule, should that help somehow ...

Edit: I think it gets delivered, because you are using lmtp, but do not have quota enabled for lmtp. You need something like I have: 

protocol lmtp {
  mail_plugins = quota fts fts_solr sieve
}
