Quota tables are used for quota *tracking*. To specify quota for a user, you need to use quota_rules. You can returns these from userdb, as quota_rule=, quota_rule2=... etc. as documented in https://wiki.dovecot.org/Quota/Configuration

Hello,

I'm running Dovecot on a FreeBSD system with Postfix in a virtual user setup, with Mysql. I am trying to understand the quota configuration.

I've got a Mysql database with an accounts table with a quota field. I've also got two other tables one quota (currently has nothing in it an empty set), and quota2 messages and bytes which has one entry. My goal is to have different quotas for each user so say one user has a 512MB quota I put 512 in the accounts quota column, while another user might have 256MB, put 256 in the accounts quota column. These are just examples. I'm assuming messages in the quota2 table track how many messages are under that user's is it inbox or all folders in the account? And bytes is that the space being taken up again by inbox or by all messages in the account?

I'm also trying to have a separate quota for my public folders, which is not working.

If anyone could take a look at this configuration see if it looks good and maybe where public is not happening i'd appreciate it.

Thanks. Dave.
