I used to have a sieve filter that copied all incoming email and put it into a folder (called Clone). It was a simple sieve 'if true.. copy' which ended up copying each email for safe keeping (disk is cheap).
I'd like to replicate that with Zimbra.
I don't think the GUI filter interface will let me do this- what is the best way to manipulate the underlying filter mechansim?
thanks for any ideas you may have.
