Postfix Question

Hello.

In the following command where it says .$mydomain what does this literally mean?

Does it mean to use this spelling exactly as is or does this mean to insert your own domain name such as XYZ.

postconf -e 'myhostname = server1.$mydomain'

Thanks

Quotation from /etc/postfix/main.cf

Quote:

# The mydomain parameter specifies the local internet domain name.
# The default is to use $myhostname minus the first component.
# $mydomain is used as a default value for many other configuration
# parameters.
#
#mydomain = domain.tld

You uncomment this line, then assign a value to mydomain. Later, when the value if recalled, it is addressed as $mydomain.

To give an example, if, as bigrigdriver suggests, you had a line that said

mydomain = domain.tld

Then the line

myhostname = server1.$mydomain

in main.cf assigns the string server1.domain.tld to variable myhostname.

Simply put, mydomain is used throughout main.cf, and doing things this way means you only have to set your domain name in one spot - the original definition of mydomain.
