holding local delivery

[Vernon A. Fort]

I have a setup where the local deliver using cyrus-imapd is located on 
an encrypted volume.  When the server is rebooted, we will manually 
mount the volume and start the cyrus application.  However, until we 
start cyrus, how can i configure postfix to accept email but defer or 
hold the local deliver indefinitely?

we do have the maximal_queue_lifetime set to 1 day.  I have set the 
defer_transports = local, soft_bounce = yes but when i setup the 
maximal_queue_lifetime to say 30 seconds, the message does get bounced 
back.  Any suggestions?
