Virtual Users And Domains With Postfix on Debian Lenny: localhost.localdomain

First of all hello to everyone since this is my first post here!

I have a question about the localhost.localdomain address that the tutorial mentions. I have installed a debian lenny system and my default value in the /etc/hosts file is 127.0.0.1 localhost.

Should I change that to 127.0.0.1 localhost.localdomain localhost ? What is this used for?

Thanks for your help & regards

 

I recommend to add localhost.localdomain because some services might use localhost.localdomain instead of localhost, and if localhost.localdomain isn't listed in /etc/hosts, then the system doesn't know which host is localhost.localdomain.

 

Thanks for the quick reply.

I read in some threads ( http://lists.debian.org/debian-devel/2005/10/msg00387.html ) that using:

instead of:

or plain:

is not a good practice. Can this change cause any problems to other services that depend on 127.0.0.1 returning localhost?

Thanks

 

I don't see how this change can cause any problems.

 

Thanks falko.

One note that probably is missing from the tutorial:

By default the spamassasin daemon is disabled.

In order to enable it one should edit the file /etc/default/spamassassin
and change:
ENABLED=0
to
ENABLED=1
