can we configure postfix in our laptop running linux?

hello all,

I have centos installed in my laptop and i want to play arounf with postfix so is it possible for me to configure postfix there without any valid hostname?

Or is that mandatory?

Hello,

Yes, you can set up Postfix on your laptop to try it out with a configuration for a local domain. The only basic thing a domain does is point to an IP, so you can configure 'whatever' you want on your computer, for example mypostfix.local. Have a look at the Postfix Standard Configuration Examples.

Kind regards,

Eric

then can i give sarah.in in the hostname? i thought we required fully qualified domain name..

Hi,

sarah.in or sarah.local for example are also valid hostnames. Just make sure that you put them in your /etc/hosts file pointing to the correct IP (127.0.0.1 if on the localhost) and make sure that in the /etc/nsswictch.conf file the hosts order lists files first so that your DNS doesn't try to resolve the domain name.

Code:

hosts: files dns

Kind regards,

Eric
