Permissions & Attributes /var/vmail recursively with dovecot

Just wanted to post this little script here, it's very useful if you're migrating users' Maildirs into an ISPConfig system under /var/vmail,
it also adds the Junk folder subscription if it wasn't already there.

Code:

#!/bin/sh

chown vmail:vmail /var/vmail/ -R
cd /var/vmail
find . -type d -name Maildir -exec chmod 700 -R {} \;
find . -type f \( -name '.sieve' -o -name '.sieve.svbin' \) -exec chmod 644 {} \;
find . -type f \( -name 'dovecot-uidlist' -o -name 'dovecot-uidvalidity' -o -name 'dovecot.index*' -o -name 'maildirsize'  \) -exec chmod 600 {} \;
find . -type f \( -name 'dovecot-uidvalidity.*'  \) -exec chmod 444 {} \;
find . -type f \( -name 'subscriptions' \) -exec chmod 744 {} \;
find . -type f \( -name 'subscriptions' \) -exec sh -c 'echo "Junk" >> "$1"' -- {} \;

exit 0

Save it as vmail.sh and run it.
