Hello all! I am currently running a very small instance of Zimbra (OS version) for my spouse and I and I have a question that I can't seem to find on the forums:

How big should I expect the index directory to get (/opt/zimbra/index)?

Currently I am supporting 5 mailboxes with around 400M of mail, but my index dir is at 5.2G! Is this normal? How fast should I expect it to grow? Do I need to ne managing the index in some way? Compressing it? Expiring data from it? Purging it?

Thanks in advance for the assistance...
