Server side is configured in policyd config file, not stored in SQL.

Just want to let you know, we achieved both per-domain and per-user sender/recipient throttling today.

You can now manage per-domain and per-user throttling in account profile page, under "Throttle" tab. With throttling, you can control:

• Max message size of single outgoing email

• Number of max outgoing emails per time unit

• Total size of outgoing emails per time unit

• Number of max incoming emails per time unit

Domain setting has higher priority by default, but you can check "Override domain setting" box in user profile page to orverride domain setting.

You can test it in our demo site: http://www.iredmail.org/admin_demo.html (Choose development edition). Feedback, suggestions and feature requests are always welcome.
