You can change post_id (not post-id). It won't break anything.

Two ways to set post_id are bin/withlist and bin/config_list. With
either method, you need to set post_id to a floating point value.
E.g., if you want to set it to 237, you need to set it to 237.0. This
can be done by putting the single line

mlist.post_id = 237.0

in a file and running

bin/config_list -i /path/to/file listname

You can also set post_id in an interactive withlist session. E.g., for
a list named test

$ bin/withlist -l test
Loading list test (locked)
The variable `m' is the test MailList instance
>>> m.post_id
>>> m.post_id = 237.0
>>> m.post_id
>>> m.Save()
Unlocking (but not saving) list: test

The last input following the m.Save() input is a control-D (end of
