Postfix Config on Arch Linux

I was following this guide & noticed that during the section I was to modify my /etc/postfix/main.cf file, do I not need to add a mydomain = mydomain.tld?

For example:

Code:

# Domain settings
myhostname = mail.mydomain.tld
[B][COLOR="Red"]mydomain = mydomain.tld[/COLOR][/B]
myorigin = mydomain.tld
mydestination = $myhostname, localhost.$mydomain, localhost

The guide tells you to reference $mydomain parameter under the "mydestination =" section however we are never instructed to enter this parameter according to the link above. Should we add the "mydomain =" parameter or is it not necessary and only clutter?

 

What are the outputs of

Code:

postconf -d | grep mydomain

and

Code:

postconf -n | grep mydomain

?

 

Code:

[root@mail ~]# postconf -d | grep -i "mydomain"
append_dot_mydomain = yes
mydestination = $myhostname, localhost.$mydomain, localhost
mydomain = localdomain

[root@mail ~]# postconf -n | grep -i "mydomain"
append_dot_mydomain = no
mydestination = $myhostname, localhost.$mydomain, localhost

 

Anyone?

 

The default setting currently is mydomain = localdomain. If you want to change it, run

Code:

postconf -e 'mydomain = mydomain.tld'

and restart Postfix.
