I'm having problems with sending emails to root on my machines at work.
My mail setup is a little strange, I suppose, but not too weird, I think
:-)

I defer all sending of email. Postfix uses a relayhost of
localhost:2300 and my user has a cronjob that sets up an ssh tunnel to a
remote host, my.remote.host, that I use to actually send the email.
(This setup is to avoid the exchange mail server that is used at the
office. I've had A LOT of problems with it and its administrators.)
The current setup works fine for sending to external addresses, but not
for sending to local ones, e.g. to root.

% /usr/lib/sendmail root << EOF
Subject: hello

hello
EOF
% mailq
2B62F4B9DD 335 Fri Sep 29 15:07:41 magnus@xxxxxxxxxxxxxx
(deferred transport)
root@xxxxxxxxxxxxxx

This is how I've configured it:

% cat /etc/mailname
my.remote.host
% egrep '^root' /etc/aliases
root: magnus
% hostname -f
my.local.host

My /etc/postfix/main.cf contains the following:

myhostname = my.local.host
myorigin = /etc/mailname
mydestination = my.local.host, localhost

How do I configure this so that emails for root are sent to
magnus@xxxxxxxxxxxxx rather than root@xxxxxxxxxxxxxx?
And, why are mails sent by the user magnus recorded as sent from
magnus@xxxxxxxxxxxxxx?

Oops, just realised that the magnus@xxxxxxxxxxxxxx is what's stuck in
the From header (different from the From: header) and that this is what
I desire. Since a lot of servers on the internet does a lookup on the
domain part I need my.remote.host there... so, just disregard the second
question.
