What, you're using maildir after all? Then you should remove this
setting:

mail_privileged_group = mail

If you're using Maildir, there's almost no chance of UIDLs changing. You
could of course manually log in and check:

telnet localhost 110
user foo
pass bar
uidl

Save the output -> look at it again after user redownloaded mails ->
compare the output to see if it had changed (besides the intentional
message deletions and new messages).
