You're specifying the list of IP addresses in an external file:

That file seems to expect expansion of "$main_dot_cf_parameter"
variables, which best I can tell/recall is not supported in such
external files.
Variable expansion in most main.cf parameters happens *before*
they are used. By the time the parameter is split into tokens
and some are interpreted as file names to read, ... all the
expansions are already done, and no further variable expansion
takes place.
