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

}

This is how I have configured it.

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"

The way I understand it is, this Quota service was built specifically for postfix. (I only have postfix, have not used any other MTA) The "quota-status" executable is in you libexec directory. ( I compiled my dovecot instance, hence is is not in "regular" directory) The "quota_status_*" are responses to postifx. AFAIK, these are the only 3 possible options.

Please see ( https://sys4.de/en/blog/2013/04/08/postfix-dovecot-mailbox-quota/ ) for a detailed info on this

When Postfix MTA is "inline" with the sender, and if you have correctly configured the quota service, it will check if the recipient's mailbox can accept mails. If the recipient is able to accept mail dovecot responds with "DUNNO" (as configured in "quota_status_success" ) to let postifx continue with its sender checks. if the recipient's mail box is unable to accept mails, the dovecot responds with "552 5.2.2 Mailbox is full" (as configured in "quota_status_overquota"), this will prevent postfix from accepting mail and will respond with 552 status . All this is documented in that blog.

Please also see: http://www.postfix.org/SMTPD_ACCESS_README.html

Where are their meanings documented?

What are the allowed values?

Are there other quota_status_* options?

Thanks in advance.

Thanks,

Michael

Hope this was helpful
