You might want to work out what is using .lock file style locking in /var/mail

The current convention is to to use O_EXLOCK normally, not that old
style locking.

I'm just using a normal simple postfix as far as I know.

I think it is intending to skip over dot files, rather than lock files.   '.'
is a valid char in user names, even if not often used, so simply
omitting files containing dots would not be a good idea.   If we wanted
to allow for old style user.lock files it would want to be skipping file
names that end in ".lock" not ones that happen to contain a '.'
(and then probably not skip, but validate that the xxx in xxx.lock is
owned by xxx)
