As a diagnostic tool, you can:

    $ telnet localhost smtp

You are greeted with an inital message; now type:


    HELO your.host.name
    MAIL FROM: user@domain.that.failed
    RCPT TO: user@your.mail.domain
    DATA
    From: Your Name <you@mail.domain>
    To: Your Name <you@mail.domain>
    Subject: Testing

    This is a test
    .
    QUIT


For each command, you get a response.  In particular, check the
response to the "MAIL FROM:" and "RCPT TO:" lines.  They should give
you a clue.



Now, using 'eximconfig', make sure you do the following:

   - Set visible name to a domain name with a valid mail exchanger
     (MX) record.  For instance, if you do 'nslookup -q=mx linux.org', 
     you will see that there are hostnames associated with it.
     "linux.org" is therefore a valid "visible name".

   - To the question:
        Does this system have any other names which may appear on
        incoming mail messages, apart from the visible name above (slett.net)
        and the system's hostname (tor.slett.net) ?

     You should answer 'localhost'.  Especially if you also are using
     'fetchmail' to retreive mail via POP3 to this machine.

   - "Networks on local machines that you want to relay mail for"
     should include 127.0.0.0/8, otherwise you will not be able to
     send mail from e.g. Netscape.   Also include the network/subnetmask
     of your network, such as 192.168.1.0/24 in the case of a typical
     IP-masqueraded network.  Your answer to this question would in
     this case be:   
                    127.0.0.0/8 192.168.1.0/24
