Or you can use a dummy backend. It's a backend which always says « OK
» when you try to write in it, and always says « not in db » when you
read in it. This backend was never committed into cyrus-imapd... Here
is an up-to-date version.
Then add this in imapd.conf :
duplicate_db: dummy
Ken, Bron : do you plan to include this backend into cyrus-imapd ?
It's very handy when we don't want to use a database (here we often
use dummy for annotations).
