several questions about zimbra mail queue management:
1. i found we got several queues whose destination email address are wrong, for instance, "yahoo.cim" while it's expected to be : yahoo.com. or "school.eud" which it's expected to be "school.edu".
these kind of queues will be kept in postfix queues for maximum lifetime (5 days) and is it possible to just reject (or delete directly) such emails in the early beginning?
2. how many concurrent mail queues and queue sizes should be considered a critical case ?
any advice ? Thanks.
