Correct. so you add addresses and/or regexps in the box, one per line,
and the data are posted to the CGI script which converts them to the
value of the list attribute acceptable_aliases which happens to be a
string which is the list of addresses separated by newlines.

It is more the translation of the entry in a web page text box into the
actual value of the list attribute.

What is in the input to config_list must be syntactically valid Python
that assigns values to list attributes. In this case, the value is a
single string consisting of the addresses/regexps separated by

There are two ways to do this in Python

- as a single-quoted string, all on one line, with newlines represented
as \n as in

acceptable_aliases = "aaa at example.com\nbbb at example.com"

- as a triple-quoted string with literal newlines as in

acceptable_aliases = """aaa at example.com
bbb at example.com"""

(note the actual quote character in either single or triple quoted
strings may be either ' or ".)

I don't know what you might think a "user friendly" format for this
might be, but it probably isn't syntactically correct Python that says
what it needs to.

Note also, that not all list attributes are represented in this way. As
another example, the owner attribute is an actual Python list of
addresses as in

owner = ['owner1 at example,com', 'owner2 at example.com']

so you have to look at an actual config_list output and emulate what
you see there for the form of each attribute you want to change.
