[Dovecot] v1.1 QUOTA and inbox quota

[Kristian Vlahovicek]

My mail agent is postfix and by default it imposes the INBOX size of 50
meg. I would like my imap mail clients (I'm using Thunderbird) to "see"
this and warn me when my inbox fills up. I tried doing it with the old
quota system but wasn't successful. With the new quota rule system it
looks like per-mailbox quotas are possible, however when I do this:

  quota = maildir
  quota_rule = INBOX:storage=50000

I get an error in the log:

Sep 28 02:18:31 discworld dovecot: IMAP(kristian): open((null)) failed:
Bad address
Sep 28 02:18:31 discworld dovecot: IMAP(kristian): Internal quota
calculation error
Sep 28 02:20:04 discworld dovecot: IMAP(kristian): open((null)) failed:
Bad address
Sep 28 02:20:04 discworld dovecot: IMAP(kristian): open((null)) failed:
Bad address


is there any way to get the inbox quota to work properly? I guess many
systems use postfix and have 50M inbox limit so it would really be
helpful if this information is pushed somehow through imap to the client.

thanks, K
