Sendmail problem

In root, when checking email in usermin I get this message:

Code:

The original message was received at Fri, 6 Feb 2004 22:18:55 GMT
from localhost.localdomain [127.0.0.1]

   ----- The following addresses had permanent fatal errors -----
<trivia@webbuild-online.com>
    (reason: 550-Verification failed for <root@localhost.localdomain>)

   ----- Transcript of session follows -----
... while talking to webbuild-online.com.:
>>> DATA
<<< 550-Verification failed for <root@localhost.localdomain>
<<< 550-unrouteable mail domain "localhost.localdomain"
<<< 550 Sender verify failed
550 5.1.1 <trivia@webbuild-online.com>... User unknown
<<< 503 valid RCPT command must precede DATA

Can anyone help me out there, I would be very happy

In any case, the problem seems to be that you don't have a valid hostname configured, and thus the recieving host doesn't want to accept the mail (since it can't verify that the sending address is valid).

How is this computer connected to the internet, and how does your network look, etc.? Do you have a registered domain name that you want to use or anything?
