Hey guys, I have a fresh installation of RH9 but I can't get it to work with sendmail. The setup is this: - RH9 running 2 NIC, it's primary roll is firewall and intranet mail. When the firewall is running it sends out all the mail that should be local, let's say that I have a domain fundekom.org (which is hosted by a third party) and the Intranet server/firewall is intra.fundekom.org the user names for fundekom.org are firstname.lastname@xxxxxxxxxxxx and the users for the Intranet are flastname@xxxxxxxxxxxxxxxxxx the problem is that users sending mail to flastname@xxxxxxxxxxxxxxxxxx get error messages from MAILER-DAEMON@xxxxxxxxxxxx with the message "<flastname@xxxxxxxxxxxx> Sorry, no mailbox here by that name." But when the firewall is not running it works fine. I had the same setup when I was running RH8 and everything worked fine. Do you know about any change in the default installation of sendmail from one version to the other (RH8 > RH9) ?? Thanks.
