[MM3-users] Saving settings of non-members does not work

I just experienced, that saving the settings of a list's non-member does not work with Postorius 1.3.13

You would need to look into the Postorius code that handles preferences. I'd start here: postorius/src/postorius/views.py, because it's not obvious to me that a non-member would even have (list-based) preferences.
