I changed the mydestination variable in /etc/postfix/main.cf to:

mydestination = localhost, $myhostname, localhost.$mydomain, $myhostname.$mydomain

and now mail to root/root@localhost is correctly forwarded to me. Thanks
for the suggestion. I am surprised this wasn't in the Postfix FAQ.

Another thing I noticed in my logs is the following postfix-related
message:

Jun 29 21:52:57 phoenix postfix/local[2536]: warning: biff_notify: Connection refused

What is biff_notify() and how can I disable this so that this message
doesn't fill up my logs ?

Lastly, is there anything else that can/should be done to secure Postfix
on a dialup system ? I have already closed my system to any outside
access using tcp_wrappers. Should I be concerned with any smtp-relaying
issues since Postfix is running on my system ?

Thanks.
