Hi, I use Dovecot 2.3.9.2 as IMAP proxy for other mail server and configure it with imapc_host/imapc_port/imapc_user options. All works fine exclude quota information. Although my IMAP server supported quota Dovecot does not relay it to users. As I read in docs/MailboxFormat.imapc.txt in Dovecot v2.2.30+ there is a way to relay quota data to end users: Quota ----- Using the "imapc" quota backend allows asking for the quota from remote IMAP server (v2.2.30+). By default it uses GETQUOTAROOT INBOX for getting the quota. There are also two parameters that can be used to control how the quota is looked up: * box=<mailbox>: Use GETQUOTAROOT <mailbox> * root=<name>: Use GETQUOTA <name> For example: ---%<------------------------------------------------------------------------- plugin { quota = imapc:root=User Quota } ---%<------------------------------------------------------------------------- The above example is not clear. Please advise how to configure Dovecot in IMAP proxy mode with quota support. -------------- next part -------------- An HTML attachment was scrubbed...
