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? __________________________________________________ Do You Yahoo!? Tired of spam?
