Okay.... here you go:

$ postconf -n
alias_maps = hash:/etc/postfix/aliases
command_directory = /usr/sbin
daemon_directory = /usr/lib/postfix
debug_peer_level = 2
default_destination_concurrency_limit = 10
default_privs = nobody
inet_interfaces = all
local_destination_concurrency_limit = 2
mail_owner = postfix
mail_spool_directory = /var/spool/mail
mailbox_command = /usr/bin/procmail -a $DOMAIN -d $LOGNAME
mydestination = $myhostname localhost.$mydomain www.$mydomain
myorigin = $mydomain
queue_directory = /var/spool/postfix
smtpd_banner = $myhostname ESMTP $mail_name

And some info on my setup...

Basically the box is meant to be the sole mail server for a very small
network. All of the mail for my domain (nondot.org) is supposed to go
there... and mail is supposed to come from xxxnondot.org.

Any more info I can help with? I really appreciate the help... I wish I
knew more about mail systems in general, because I never appreciated the
complexity and available options before!
