<chop> Fallback.nl.uu.net is rejecting the e-mail because the MTA on your nagios box, not nagios itself, is claiming to be called localhost.localdomain, which is an unverifiable name. It's very reasonable that they would do that. You need to configure the MTA on your nagios box to use a real hostname that can be found in the DNS. This may be as simple as adding the hostname to your DNS and editing your /etc/hosts file on your nagios box, changing the 127.0.0.1 entry to something like -- 127.0.0.1 yourhost.yourdomain.foo localhost.localdomain You'd need to restart your MTA if it's running as a daemon after making that change. If that doesn't work, you'll need to specifically configure the MTA that you're using to masquerade as that host or domain. You can do this for Sendmail by setting the MASQUERADE_AS macro. Under Postfix I believe it's the myorigin variable. -- Marc ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
