I have set up a mail server at work using Linux and the internet as my guide. I am completely new to Linux but managed to get everything working somehow....
Now I get my daily LogWatch email from my email server and I the only error that I get is listed below. This error occurs a good bit, but does not seem to affect the function of the program. I searched for an answer on the net and there does not seem to be a consensus on what to do to fix it (or my not being able to understand a thing some of the posts said might have something to do with it too!) I just wanted to be able to fix it and clean up my log files some.
I am using Fedora Core 5 with Postfix, Spamassassin, Amavis, and ClamAV.
Here is the error section which shows up in the PostFix section. It goes on for pages, so I truncated it.
Since I am so fresh at this, I would appreciate any replies in "Step by Step for Dummies" format.

It also could be that your resolv.conf (the file containing your internal and external DNS resolution settings) could differ from the "jailed" postfix version of the file. If you see this practically constantly then there are other checks to perform, such as
egrep -i warning /var/log/mail/*
(provided your server is default setup to log to /var/log/mail)
In which case you should copy /etc/resolv.conf to /var/spool/postfix/etc/
Thanks Kblack,
I am not sure what "egrep -i warning /var/log/mail/" does, but I didn't get any errors when I ran it. (I always run commands that I don't understand...sometimes the results are interesting! ;-)
I did not have an etc folder under /var/spool/postfix/. I created one and copied my resolv.conf file to it. Will see what the log does tomorrow.
Thanks for the replies

Well if your mail is working, then I'd suggest that these are actually not server errors, but that the remote IP address is not delegated in DNS , or perhaps is spoofed.
(If nothing is broken, I wouldn't worry about it too much. You should probably check that it's not an open relay with http://www.abuse.net/relay
As you can see, at least two of the above addresses will not look up on other NS servers as well, indicating this is not isolated to your box.
