I run Mandrake linux on comcast cable.
Here are the chamges I made for my LAN.
wb.home is my web browsing box where postfix is running.

Some Mail Transport Agents (MTA) will not accept incomming mail
unless the originator eamil id is a vaild email address at the relayhost.
To solve that problem I created the sender_canonical file to
replace my bittwister id with my  email id at comcast.net.

My change is the < line
the original is  > line
68 is line number in main.cf 67 is line number in main.cf_orig

diff main.cf main.cf_orig
68d67
< myhostname = wb.home
77d75
< mydomain = home
306c304
< relayhost = smtp.comcast.net

To test
postfix stop
postfix start

check your logs in /var/log/mail
