I am running Linux with a small local network. But there's a problem with sendmail when I want to send mail to another machine. The following line comes from the mail-log (/var/log/mail):
Jun 25 07:23:25 pc8 sendmail: SAA00404: to=<firstname.lastname@example.org>, ctladdr=<email@example.com> (500/100), delay=1+13:16:20, xdelay=00:00:00, mailer=esmtp, relay=pc1.woodnet., stat=Deferred: Name server: pc1.woodnet.: host name lookup failure
(I want to send mail from pc8.woodnet to pc1.woodnet)
I think I have installed sendmail with a standard config for use with a DNS (which I don't have). But as a rookie I don't know what's the right way to do it...
Would be nice, if someone could lend me a hand! ;)
