I've recently setup a new backup server and have configured sendmail with a smart_relay_host
Except every email from the command line doesn't go anywhere. From mail.log:
Oct 3 14:32:52 **back01 sm-mta[16570]: p93DWqtC016568: to=<
[email protected], ctladdr= (0/0), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=120762, relay=10.2.30.60, dsn=5.1.2, stat=Host
unknown (Name server: 10.2.30.60: host not found)
Oct 3 14:32:52 ***back01 sm-mta[16570]: p93DWqtC016568: p93DWqtC016570: DSN: Host
unknown (Name server: 10.2.30.60: host not found)
DNS is working correctly on this box. I can do forward and reverse lookups.
I can also telnet to the mail relay and send a message that way.
I'm stumped, any suggestions?
