Hi All, I have tried enabling quota and plugins in dovecot.conf and the roundcube webmail still shows quota as unlimited. User maximum quota is stored in mysql. I tried configuring dovecot-dict-quota.conf also but failed to connect to sql. The sql database is from the ISPconfig 2. The user quota is located in "user_speicher" field. *******(contents of dovecot.conf is as below********** protocol imap { mail_plugins = quota imap_quota } dict { quotadict = mysql:/etc/dovecot-dict-quota.conf } quota = dict:user :: proxy::quotadict quota = maildir ****contents of dovecot-dict-quota.conf is as below******** driver = mysql connect = host=localhost dbname=db_ispconfig user=YYY password=XXXXX default_pass_scheme = PLAIN table = isp_isp_user select_field = user_speicher where_field = ?????? username_field = user_username Have anyone successfully setup the quota? Please let me know Tks in advance. Teddy.
