dovecot - Apr 2013 - How to prevent delivery to mailboxes over quota at SMTP-time

Hi!

I wrote a little something about how to prevent delivery to mailboxes
over quota while still being in the SMTP dialogue:

Hi Ralf,

played around with it a bit. There is another thread here which indicates people
couldn't get it to work. With the latest and greatest it seems to have some
query issue:

[...]
Apr 12 09:22:04 spectre postfix/smtpd[18355]: warning: access table
inet:127.0.0.1:10027 entry  has empty value
[...]

Regards
Thomas

Cool, thanks for posting that.  I guess I'll have to upgrade, I think
we're dovecot 2.0.

After some mails have been accepted it starts to reject like this:
