We are looking at switching our entire company from sendmail to zimbra. Our customers require that we be able to follow a DoD approved method for wiping sensitive emails (multi-pass wiping). I have just gone in to /opt/ximbra/store/0/<id>/msg/0/ and ran bcwipe on a .msg file. I can not longer find the file anywhere on the server but when I log into my Zimbra account the email is still sitting there. Is this message cached somewhere else?
