Hi, I'm directly connected to the Internet via a router. After the router is a Linux box with 3 network adapter. eth0 is connected to the router, eth1 is connected to the mail server and eth2 is connected to the local LAN with a private IP addresses (10.x.x.x) through a switch. The mails are not able to get to the users. I could see that the mails are not appended in the /var/spool/mail/(USERS) file. Instead they go to the mqueue directory to return to senders with a fatal error message, "Host Unknown". When I tested "host aa.bb.cc", I received the right response. The log file has this: incoming mail: May 26 23:39:17 mail sendmail [24922]: delay 00:00:00, xdelay 00:00:00, mailer=relay, relay=No, stat= Host Unknown (Name server: no: no data known) internal mail: May 26 23:40:18 mail sendmail [28041]: XAA28041: from=<[EMAIL PROTECTED]> size=0, class=0, pri=0, nrcpts=0, proto=ESMTP, relay=[10.50.80.70] outgoing mail: May 26 23:40:25 mail sendmail [28042]: NOQUEUE: Null connection from [10.50.80.70] What can be wrong? Any help is greatly appreciated. Danny - To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to [EMAIL PROTECTED]
