Cyrus deliver temporary failure (quota not full)

[Hardi Gunawan]

Hi,

I have a peculiar problem with Postfix and Cyrus. 
Somehow cyrus returns a temporary failure to Postfix,
with no other detailed information.

I've checked that the users affected have their
mailbox not overquota.  In fact, they can receive
emails at nearly the same time (around 1-2 seconds
difference) as the temporary failure.

It seems that when there is a Cc, some of the users
experience this, but when a direct one-to-one email to
the users, they can receive.

I tried to find out how to increase the log level for
cyrus' deliver, but I can't find one...

Can anyone help me?
