[Dovecot] Migrate courierimapsubscribed to subscriptions

[Alessio Cecchi]

Hi

here's a little trick to migrate from courierimapsubscribed to subscriptions:

create a file /usr/local/bin/courier-dovecot-subscribe-migrate like this:

#!/bin/sh
# WARNING: Be sure to use mail_drop_priv_before_exec=yes,
# otherwise the files are created as root!

if [ -e ~/Maildir/courierimapsubscribed ]
then
	cat ~/Maildir/courierimapsubscribed | sed -e 's/INBOX\.//' > 
~/Maildir/subscriptions
	mv ~/Maildir/courierimapsubscribed ~/Maildir/courierimapsubscribed-VIA
fi
# This is for imap, create a similar script for pop3 too
exec /usr/libexec/dovecot/imap

remember to chmod 755 /usr/local/bin/courier-dovecot-subscribe-migrate

after in your dovecot.conf add:

mail_drop_priv_before_exec=yes
mail_executable=/usr/local/bin/courier-dovecot-subscribe-migrate

reload dovecot and now on the first IMAP login (like via webmail) your 
subscriptions folders will be migrate to dovecot format.

Ciao
