postfix-2.1.1,1 - Recipient address rejected: Access denied

[Edward Carmody]

I cannot receive email to local accounts from other mail servers (my other
accounts).  /var/log/maillog has (for example) multiple instances of:
---------------------------------------------------------------------------

---------------------------------------------------------------------------

My /etc/postfix/main.cf is so:
---------------------------------------------------------------------------
[root at oberon /root] # cat /etc/postfix/main.cf
queue_directory = /var/spool/postfix
command_directory = /usr/local/sbin

mynetworks_style = subnet
mynetworks = 192.168.X.X/24, 127.0.0.0/8
alias_maps = hash:/etc/mail/aliases
local_recipient_maps = proxy:unix:passwd.byname $alias_maps
#alias_database = dbm:/etc/mail/aliases
#mail_spool_directory = /var/spool/mail

---------------------------------------------------------------------------

I would want to be checking users against /etc/passwd, I guess.  Is there
something wrong with my local_recipient_maps statement?

Also, postconf -v mail_version reports "mail_version = 2.0.18", but pkg_info
shows "postfix-2.1.1,1".  Obviously, I upgraded, but didn't do something
quite right.

Any help greatly appreciated.  Thanks!
