I’m usually a postfix guy. That’s what I run on my servers and it’s the configuration I understand. So when someone asked me to take a look at an issue on a server running sendmail, I was a bit befuddled.
The problem was that any messages sent from the command line, were arriving with a from address of root@localhost.localdomain. This was a bit of a problem. To test and confirm I ran the following:
view sourceprint?
1
echo "Who will this message be addressed from? The world may never know." | mail -s "Testing sendmail" alex
And sure enough, I get an email address from root@localhost.localdomain. I end up Googling combinations of ‘root@localhost.localdomain’, ‘localhost.localdomain’ and ‘sendmail’. The options were pretty much useless. Too much noise about changing the sendmail configuration options.
In the end, I stumbled upon the real way to fix it….

Open /etc/hosts and change add the host’s name before the localhost.localdomain entry on the first line.

127.0.0.1 host.foobar.com host localhost.localdomain localhost

::1 localhost6.localdomain6 localhost6

Turns out, sendmail looks for the first hostname in the hosts file for the loopback address and uses that in the from field when a from address isn’t specified by the mail client.
