Any idea how they get out of synch?  I hadn't created a new list for awhile 
when it started screwing up.  Here are some observations after reading the 
info at the link above:

1.  Regarding the ownership of aliases and aliases.db, mine are "reversed" -

aliases - Owner = www-data, Group = list
aliases.db - Owner = list, Group - www-data

I don't know if that's how they used to be or not.

Permissions for both files is 0660.

Would you suggest that I change both to owner = list and group = www-data 
and then run bin/genaliases?

The aliases file only has information for 2 of my lists - The 2 that work 
BTW!

I tried running genaliases yesterday, but I think it didn't work correctly 
due to permissions mismatch.
