.lan is very like your, and that alias works
here. And I can send to [email protected]

A remaining difference I can think of is that I'm using DNS as I described a while ago.
You are using a DNS (for outside users) and your hosts files, for computers
in the same domain. This is a setup I mostly avoid. I do do that for, and incoming email addressed to addresses in that
domain get relayed inside my home network to another system, and for that I
need my own DNS with different information from the public DNS.
There is *no* incoming mail or outgoing mail, I read my mail elsewhere
by connecting to a remote system using ssh.  All I want is to be able
to see mail sent to root on the local system so I can monitor it.
This doesn't prevent it from being confused.
I prefer postfix, I find it easier.

When I ran a mail server on this system I too used postfix, *much*
easier to configure.  But now I don't want any sort of mail server
except to get the local delivery of root mail.
Please run this test and post the results:
telnet 25
ehlo fred

Where from?  It's not going to work from most places because the
firewall doesn't allow connections on port 25, this system isn't
intended to accept any mail from outside.
Whereever it works. It will tell us sendmail's idea of the host name.

Like this:

[[email protected] mail]# telnet 25
Connected to
Escape character is '^]'.
220 potoroo.demo.lan ESMTP Sendmail 8.14.1/8.14.1; Mon, 12 Nov 2007 20:50:08 +0900
ehlo potoroo.demo.lan
250-potoroo.demo.lan Hello localhost.localdomain [], pleased to meet you
250 HELP
221 2.0.0 potoroo.demo.lan closing connection
Connection closed by foreign host.
[[email protected] mail]#

If this happens,
[[email protected] mail]# telnet potoroo.demo.lan 25
telnet: connect to address Connection refused
[[email protected] mail]#

then telnet as in the first example.
