Migrate maildirs from Courier to Dovecot

Got courier-dovecot-migrate.pl from http://wiki.dovecot.org/Migration/Courier

Old structure of maildirs was domain/user/.maildir I needed to convert that to domain/user with the script below

#!/bin/bash
./courier-dovecot-migrate.pl --to-dovecot --recursive --convert domaindirectory
for f in `find -name .maildir`; do
  PARENT=`dirname $f`
  mv $f/* $f/.[^.]* $PARENT
done

Bulk rename files

Rename all en. to et. in files down the tree with find:

find -type f -exec rename -v -n 's/en\./et\./' {} \;
