I'm trying to understand the quota-status service, but I can't find complete documentation. The quota-status service is mentioned here: http://wiki.dovecot.org/Quota And an example configuration is shown: service quota-status { executable = quota-status -p postfix inet_listener { port = 12340 # You can choose any port you want } client_limit = 1 } But I can't find any information on quota-status. "man quota-status" returns nothing. I am unable to find a "quota-status" file on my machine. Where is the executable located? What does the "-p postfix" option do? Are there any other command line options? The above wiki page shows three quota_status_* options in use: quota_status_success = DUNNO quota_status_nouser = DUNNO quota_status_overquota = "552 5.2.2 Mailbox is full" Where are their meanings documented? What are the allowed values? Are there other quota_status_* options? Thanks in advance. Thanks, Michael
