[K12OSN] Users' Maildir directories

[Michael Blinn]

I've had an issue with users trying to "clean out" their home 
directories and they inadvertantly remove postfix/dovecot's Maildir 
directory containing all their email. Does anyone know of any downsides 
to changing this to .Maildir to prevent this from happening in the 
future? Or perhaps are there other methods of fixing the problem?
Cheers,
