Hi Zhang,

We got similar issue as the post, users cannot receive any mail even for local delivery but send out is ok.
http://www.iredmail.org/forum/topic2534 … error.html

Error: dict sql lookup failed: Table 'vmail.used_quota' doesn't exist
Error: Internal quota calculation error

failed to store into mailbox 'INBOX': Internal error occurred. Refer to server log for more information.

location=maildir://var/vmail/vmail1/yelites.com/peter//Maildir/:INDEX=//var/vmail/vmail1/yelites.com/peter//Maildir/

IMAP Error: Could not save message in Sent in /var/www/roundcubemail-0.8.4/program/steps/mail/sendmail.inc on line 704 (POST /mail/?_unlock=loading1355151051523&_lang=undefined?_task=mail&_action=send)

BTW, I found there is no "vmail.used_quota" table, is it generated by dovecot or should be original part of iredmail install? If that, how may I recreate it?

urgent waiting, Thanks Zhang!
