Administrator Logging - Able to track deleted aliases?

[omegainstitute]

We had a mysterious event occur yesterday, in that a bunch of our aliases "disappeared" off our Zimbra installation. Is there a logfile I can parse to see if an admin had removed the alias?

I took a quick look through the Wiki and it only mentions MTA logging and statistical logging.

Thanks for your time,

Rob

I don't know of this off hand but...

Can you create an alias for testing, then delete it, then grep all of the /opt/zimbra/log files to see what (if any) entries are made in the logs?
