Okay, so I got a little further.  I modified the local_reciepient_maps
value as such:
local_recipient_maps = hash:/private/etc/postfix/shared_folders

So now it stops bugging me about not being able to find the shared_folders.db,
but now I can't send mail to anyone on our test system, and sending to
"Conference+News@<domain>" eventually comes back with an "I'm sorry I couldn't
deliver" message, saying:

Final-Recipient: rfc822; Conference+News@<domain>
Action: Failed
Status 5.0.0
Diagnostic-Code: X-Postfix; data format error. Command output: Conference+News:
Mailbox does not exist

I realize this is more of a postfix problem than a Cyrus one, but does anyone
have any further suggestions?
