I have (control over) a bunch of computers, and they're not all configured the same. The machine I believe you refer to is this one: wooledg@wooledg:~$ hostname wooledg wooledg@wooledg:~$ hostname -f wooledg This is a dual-boot Windows/Debian workstation on my desk at work. Here's the /etc/hosts: wooledg@wooledg:~$ cat /etc/hosts 127.0.0.1 localhost 127.0.1.1 wooledg # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters The hostname is defined in DNS (originally I just let it have a dynamic IP address and dealt with that, but later I arranged for it to have a non-changing IP address, for reasons beyond the scope of this email; but in all cases, DNS always had a working "A" record). It looks like this one is running exim: wooledg@wooledg:~$ ps -ef | grep exim Debian-+ 949 1 0 Nov14 ? 00:00:00 /usr/sbin/exim4 -bd -q30m wooledg 10865 2007 0 07:53 pts/4 00:00:00 grep exim I never saw any errors like the one you showed, perhaps because exim used my default search domain (from /etc/resolv.conf) and found a sane DNS configuration, or perhaps because this machine is in a very simple "send to smarthost only" mode. I don't really know exim very well. I have other systems that run qmail (locally installed), and even one that runs sendmail (part of the hosting provider's original image, and I never bothered to replace it). The only major MTA with which I have absolutely no experience at all is postfix.
