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.

 

Thanks mate!!
Just swapped servers and also changed to dovecot from courier.
Thunderbird could not delete or rename folders, saying something like 'cannot renaming not supported across conflicting directory permissions'.
Your script fixed it.
I noticed before maildir permissions were drwxrws--- and now drwx--S---
Is this what dovecot expect to be the maldir? Should I remove the setid setgid bit?
Best regards, and thanks again!!!!
