I was messing around with making this work, and I almost got it, but ran 
into a problem.  I changed the line in main.cf to:

mailbox_command = /usr/local/libexec/dovecot/deliver -n -m "$EXTENSION"

Now, in my logs it displays this:

Apr 16 17:02:34 apple postfix/local[5990]: 3BFF77B8F24: 
to=<jeff+Dad at stikman.com>, relay=local, delay=0.06, 
delays=0.01/0.03/0/0.02, dsn=2.0.0, status=sent (delivered to command: 
/usr/local/libexec/dovecot/deliver -n -m "$EXTENSION")

and tries to save the message in the dad folder.  The only problem is 
the dad folder is listed as "Dad" and no matter what I put in the e-mail 
address, capital "D" or lowecase "D", it always tries to save it do 
"dad" which does not exist.

deliver(jeff): msgid=<49E7C710.7060702 at stikman.com>: save failed to dad: 
Mailbox doesn't exist: dad

Do I have to change all of my folder names to lowercase, or is there a 
easier fix I am missing?

Also, a different problem in regards to this also.  Now I am getting the 
following lines in my maillog file:

Apr 16 17:02:34 apple dovecot: deliver(jeff): sieve runtime error: Keep: 
Generic
  Error
Apr 16 17:02:34 apple dovecot: deliver(jeff): 
sieve_execute_bytecode(/home/jeff/sievec) failed

This only started after I changed the deliver line in main.cf.  If I can 
get + addressing working, I don't need the sieve script so I will remove it.

Thanks,
Jeff
