That's no problem either. The question is: Are you looking for an automated process or does "cp -a template_maildir/ /srv/mail/newuser/" the job?
It should be automated. A possible solution would be a cronjob, which checks every few minutes if there is a new user without a maildir. But this requires that the user hasn't logged on before the cronjob is executed. Another approach is to check every maildir for an existing .Spam folder and a .dovecot.sieve file and create both if they don't exist. If dovecot couldn't do this by itself, I'm going to realize it with a cronjob.
Why not just do this with a post-logon script? http://wiki.dovecot.org/PostLoginScripting -- Best regards, Charles
