Regarding Zimbra Message Lifetime

[Ranjithravi]

We want our users to maintain 6 months mails only, so we found the below command to purge the mails older than 6 months.

But the issue is, it processing mailboxes one by one with time interval of 1 minute. so its taking lot of time.

In order to reduce the time, we want to purge mails older than 6 months in all mailboxes at a time. Please let us know the solution.
