since parameters can be user defined, i think it would be good if the
documentation stated this, maybe in postconf(5)? it would alleviate
guessing games.
possibly something like:
Postfix main.cf file format
[...]
• A logical line starts with non-whitespace text. A line that starts
with whitespace continues a logical line.
• Parameter names are limited to the character set [a-zA-z0-9_].
• A parameter value may refer to other parameters.
